German tank t 3 sizes. Jobs for the crew of the tank Pz.III

Modern battle tanks Russia and the world photo, video, pictures watch online. This article gives an idea of ​​the modern tank fleet. It is based on the classification principle used in the most authoritative reference book to date, but in a slightly modified and improved form. And if the latter in its original form can still be found in the armies of a number of countries, then others have already become a museum exhibit. And all for 10 years! Follow in the footsteps of Jane's handbook and not consider this combat vehicle (very curious in design and fiercely discussed at the time), which formed the basis tank park the last quarter of the 20th century, the authors considered it unfair.

Films about tanks where there is still no alternative to this type of weapon ground forces. The tank was and probably will remain for a long time modern weapons due to the ability to combine such seemingly contradictory qualities as high mobility, powerful weapons and reliable crew protection. These unique qualities of tanks continue to be constantly improved, and the experience and technologies accumulated over decades predetermine new frontiers of combat properties and military-technical achievements. In the age-old confrontation "projectile - armor", as practice shows, protection from a projectile is being improved more and more, acquiring new qualities: activity, multi-layeredness, self-defense. At the same time, the projectile becomes more accurate and powerful.

Russian tanks are specific in that they allow you to destroy the enemy from a safe distance, have the ability to perform quick maneuvers on impassable roads, contaminated terrain, can “walk” through the territory occupied by the enemy, seize a decisive bridgehead, induce panic in the rear and suppress the enemy with fire and caterpillars . The war of 1939-1945 became the most difficult test for all mankind, since almost all countries of the world were involved in it. It was the battle of the titans - the most unique period that theorists argued about in the early 1930s and during which tanks were used in large numbers by almost all the warring parties. At this time, a "check for lice" and a deep reform of the first theories of the use of tank troops took place. And it is the Soviet tank troops that are most affected by all this.

Tanks in battle that became a symbol of the past war, the backbone of the Soviet armored forces? Who created them and under what conditions? How did the USSR, having lost most of its European territories and having difficulty recruiting tanks for the defense of Moscow, be able to launch powerful tank formations on the battlefield already in 1943? This book, which tells about the development of Soviet tanks "in the days of testing ", from 1937 to the beginning of 1943. When writing the book, materials from the archives of Russia and private collections of tank builders were used. There was a period in our history that was deposited in my memory with some depressing feeling. It began with the return of our first military advisers from Spain, and stopped only at the beginning of forty-three, - said the former general designer Self-propelled guns L. Gorlitsky, - some kind of pre-stormy state was felt.

Tanks of the Second World War, it was M. Koshkin, almost clandestinely (but, of course, with the support of "the wisest of the wise leader of all peoples"), who was able to create that tank that, a few years later, will shock German tanks th generals. And what’s more, he didn’t just create it, the designer managed to prove to these stupid military men that it was his T-34 that they needed, and not just another wheeled-tracked “highway”. The author is in slightly different positions that he formed after meeting with the pre-war documents of the RGVA and RGAE. Therefore, working on this segment of the history of the Soviet tank, the author will inevitably contradict something "generally accepted". This work describes the history Soviet tank building in the most difficult years- from the beginning of a radical restructuring of the entire activity of design bureaus and people's commissariats as a whole, during a frantic race to equip new tank formations of the Red Army, the transfer of industry to wartime rails and evacuation.

Tanks Wikipedia the author wants to express his special gratitude for the help in the selection and processing of materials to M. Kolomiyets, and also to thank A. Solyankin, I. Zheltov and M. Pavlov, the authors of the reference publication "Domestic armored vehicles. XX century. 1905 - 1941" because this book helped to understand the fate of some projects, unclear before. I would also like to recall with gratitude those conversations with Lev Izraelevich Gorlitsky, the former Chief Designer of UZTM, which helped to take a fresh look at the entire history of the Soviet tank during the Great Patriotic War Soviet Union. Today, for some reason, it is customary to talk about 1937-1938 in our country. only from the point of view of repressions, but few people remember that it was during this period that those tanks were born that became legends of the wartime ... "From the memoirs of L.I. Gorlinkogo.

Soviet tanks, a detailed assessment of them at that time sounded from many lips. Many old people recalled that it was from the events in Spain that it became clear to everyone that the war was getting closer to the threshold and it was Hitler who would have to fight. In 1937, mass purges and repressions began in the USSR, and against the backdrop of these difficult events, the Soviet tank began to turn from a "mechanized cavalry" (in which one of its combat qualities protruded by reducing others) into a balanced combat vehicle, which simultaneously had powerful weapons, sufficient to suppress most targets, good cross-country ability and mobility with armor protection, capable of maintaining its combat effectiveness when shelling a potential enemy with the most massive anti-tank weapons.

Large tanks were recommended to be added to the composition only special tanks- floating, chemical. The brigade now had 4 separate battalions of 54 tanks each and was reinforced by the transition from three-tank platoons to five-tank ones. In addition, D. Pavlov justified the refusal to form in 1938 to the four existing mechanized corps three more additionally, believing that these formations are immobile and difficult to control, and most importantly, they require a different organization of the rear. The tactical and technical requirements for promising tanks, as expected, have been adjusted. In particular, in a letter dated December 23 to the head of the design bureau of plant No. 185 named after. CM. Kirov, the new chief demanded to strengthen the armor of new tanks so that at a distance of 600-800 meters (effective range).

The latest tanks in the world when designing new tanks, it is necessary to provide for the possibility of increasing the level of armor protection during modernization by at least one step ... "This problem could be solved in two ways. Firstly, by increasing the thickness of the armor plates and, secondly," by using increased armor resistance". It is easy to guess that the second way was considered more promising, since the use of specially hardened armor plates, or even two-layer armor, could, while maintaining the same thickness (and the mass of the tank as a whole), increase its durability by 1.2-1.5 It was this path (the use of specially hardened armor) that was chosen at that moment to create new types of tanks.

Tanks of the USSR at the dawn of tank production, armor was most massively used, the properties of which were identical in all directions. Such armor was called homogeneous (homogeneous), and from the very beginning of the armor business, the craftsmen strove to create just such armor, because uniformity ensured stability of characteristics and simplified processing. However, at the end of the 19th century, it was noticed that when the surface of the armor plate was saturated (to a depth of several tenths to several millimeters) with carbon and silicon, its surface strength increased sharply, while the rest of the plate remained viscous. So heterogeneous (heterogeneous) armor came into use.

In military tanks, the use of heterogeneous armor was very important, since an increase in the hardness of the entire thickness of the armor plate led to a decrease in its elasticity and (as a result) to an increase in brittleness. Thus, the most durable armor with other equal conditions it turned out to be very fragile and often pricked even from bursts of high-explosive fragmentation shells. Therefore, at the dawn of armor production in the manufacture of homogeneous sheets, the task of the metallurgist was to achieve the highest possible hardness of the armor, but at the same time not to lose its elasticity. Surface-hardened by saturation with carbon and silicon armor was called cemented (cemented) and was considered at that time a panacea for many ills. But cementation is a complex, harmful process (for example, processing a hot plate with a jet of lighting gas) and relatively expensive, and therefore its development in a series required high costs and an increase in production culture.

Tank of the war years, even in operation, these hulls were less successful than homogeneous ones, since for no apparent reason cracks formed in them (mainly in loaded seams), and it was very difficult to put patches on holes in cemented slabs during repairs. But it was still expected that a tank protected by 15-20 mm cemented armor would be equivalent in terms of protection to the same, but covered with 22-30 mm sheets, without a significant increase in mass.
Also, by the mid-1930s, in tank building, they learned how to harden the surface of relatively thin armor plates by uneven hardening, known since the end of the 19th century in shipbuilding as the "Krupp method". Surface hardening led to a significant increase in hardness front side sheet, leaving the main thickness of the armor viscous.

How tanks shoot videos up to half the thickness of the plate, which, of course, was worse than carburizing, since despite the fact that the hardness of the surface layer was higher than during carburizing, the elasticity of the hull sheets was significantly reduced. So the "Krupp method" in tank building made it possible to increase the strength of armor even somewhat more than carburizing. But the hardening technology that was used for sea armor of large thicknesses was no longer suitable for relatively thin tank armor. Before the war, this method was almost never used in our serial tank building due to technological difficulties and relatively high cost.

Combat use of tanks The most developed for tanks was the 45-mm tank gun mod 1932/34. (20K), and before the event in Spain, it was believed that its power was enough to perform most tank tasks. But the fighting in Spain showed that the 45-mm gun can only satisfy the task of fighting enemy tanks, since even the shelling of manpower in the conditions of mountains and forests turned out to be ineffective, and it was only possible to disable a dug-in enemy firing point in the event of a direct hit. Shooting at shelters and bunkers was ineffective due to the small high-explosive action of a projectile weighing only about two kg.

Types of tanks photo so that even one hit of a projectile reliably disables an anti-tank gun or machine gun; and thirdly, to increase the penetrating effect of a tank gun on the armor of a potential enemy, since, using the example of French tanks (already having an armor thickness of the order of 40-42 mm), it became clear that the armor protection of foreign combat vehicles tends to be significantly increased. There was a right way to do this - increasing the caliber of tank guns and simultaneously increasing the length of their barrel, since a long gun of a larger caliber fires heavier projectiles at a higher muzzle velocity over a greater distance without correcting the pickup.

The best tanks in the world had a large caliber gun, also had a large breech, significantly more weight and increased recoil reaction. And this required an increase in the mass of the entire tank as a whole. In addition, the placement of large shots in the closed volume of the tank led to a decrease in the ammunition load.
The situation was aggravated by the fact that at the beginning of 1938 it suddenly turned out that there was simply no one to give an order for the design of a new, more powerful tank gun. P. Syachintov and his entire design team were repressed, as well as the core of the Bolshevik Design Bureau under the leadership of G. Magdesiev. Only the group of S. Makhanov remained at liberty, who from the beginning of 1935 tried to bring his new 76.2-mm semi-automatic single gun L-10, and the team of plant No. 8 slowly brought the "forty-five".

Photos of tanks with names The number of developments is large, but in mass production in the period 1933-1937. not a single one was accepted ... "In fact, none of the five air-cooled tank diesel engines, which were worked on in 1933-1937 in the engine department of plant No. 185, was brought to the series. Moreover, despite the decisions on most upper levels about the transition in tank building exclusively to diesel engines, this process was hampered by a number of factors. Of course, diesel had significant efficiency. It used less fuel per unit of power per hour. Diesel fuel is less prone to ignition, since the flash point of its vapors was very high.

Even the most finished of them, the MT-5 tank engine, required reorganization of engine production for serial production, which was expressed in the construction of new workshops, the supply of advanced foreign equipment (there were no machine tools of the required accuracy yet), financial investments and strengthening personnel. It was planned that in 1939 this diesel engine with a capacity of 180 hp. will go to production tanks and artillery tractors, but due to investigative work to find out the causes of tank engine accidents, which lasted from April to November 1938, these plans were not fulfilled. The development of a slightly increased six-cylinder gasoline engine No. 745 with a power of 130-150 hp was also started.

Brands of tanks with specific indicators that suited the tank builders quite well. Tank tests were carried out according to a new methodology, specially developed at the insistence of the new head of the ABTU D. Pavlov in relation to combat service in wartime. The basis of the tests was a run of 3-4 days (at least 10-12 hours of daily non-stop traffic) with a one-day break for technical inspection and restoration work. Moreover, repairs were allowed to be carried out only by field workshops without the involvement of factory specialists. This was followed by a "platform" with obstacles, "bathing" in the water with an additional load, simulating an infantry landing, after which the tank was sent for examination.

Super tanks online after the improvement work seemed to remove all claims from the tanks. And the general course of the tests confirmed the fundamental correctness of the main design changes - an increase in displacement by 450-600 kg, the use of the GAZ-M1 engine, as well as the Komsomolets transmission and suspension. But during the tests, numerous minor defects again appeared in the tanks. Chief designer N. Astrov was suspended from work and was in custody and under investigation for several months. In addition, the tank received a new improved protection turret. The modified layout made it possible to place on the tank a larger ammunition load for a machine gun and two small fire extinguishers (before there were no fire extinguishers on small tanks of the Red Army).

US tanks as part of modernization work, on one serial model of the tank in 1938-1939. the torsion bar suspension developed by the designer of the Design Bureau of Plant No. 185 V. Kulikov was tested. It was distinguished by the design of a composite short coaxial torsion bar (long monotorsion bars could not be used coaxially). However, such a short torsion bar in tests did not show good enough results, and therefore the torsion bar suspension during further work did not immediately pave the way. Obstacles to be overcome: rises not less than 40 degrees, vertical wall 0.7 m, overlapping ditch 2-2.5 m.

Youtube about tanks work on the production of prototypes of D-180 and D-200 engines for reconnaissance tanks is not being carried out, jeopardizing the production of prototypes. 10-1), as well as the amphibious tank version (factory designation 102 or 10-2), are a compromise solution, since it is not possible to fully meet the requirements of the ABTU.Variant 101 was a tank weighing 7.5 tons with a hull according to the type of hull, but with vertical side sheets of case-hardened armor 10-13 mm thick, because: "Sloped sides, causing serious weighting of the suspension and hull, require a significant (up to 300 mm) broadening of the hull, not to mention the complication of the tank.

Video reviews of tanks in which the power unit of the tank was planned to be based on the 250-horsepower MG-31F aircraft engine, which was mastered by the industry for agricultural aircraft and gyroplanes. Gasoline of the 1st grade was placed in a tank under the floor of the fighting compartment and in additional onboard gas tanks. The armament fully met the task and consisted of coaxial machine guns DK caliber 12.7 mm and DT (in the second version of the project even ShKAS appears) caliber 7.62 mm. The combat weight of a tank with a torsion bar suspension was 5.2 tons, with a spring suspension - 5.26 tons. The tests were carried out from July 9 to August 21 according to the methodology approved in 1938, with special attention paid to tanks.

Having started World War II with the invasion of Poland, Germany had only about a hundred Panzer III tanks, so in the Polish campaign and battles with the French and British armies in the west, this tank was not so noticeable among the mass of more outdated tanks, which at that time were armed with tank troops Germany. But by the beginning of the Wehrmacht's eastern campaign, the Pz.III had already become the main tank of the German army. On June 22, 1941, there were 965 Panzer III tanks on the Soviet borders.

Description

The development of the Panzer III medium tank has been carried out since 1934 by such well-known German concerns as Friedrich Krupp, MAN, Daimler-Benz and Rheinmetal Borsing. Each of the manufacturers presented their tank sample. As a result, the military preferred the Daimler-Benz project. The tank was put into production in 1937 and received its final name - "Pz.Kpfw.III". The first modification "Panzer III Ausf.A" had only bulletproof armor - 14.5mm and a 37mm gun. The tank was quickly improved and refined. Modifications A, B, C, D and E were released in small batches. The first large batch (435 units) produced the tank "Panzer III Ausf.F". Most of the F modification tanks were already armed with the 50 mm KwK 38 L/42 cannon. Reinforced frontal armor was now 30mm. The tank continued to be improved, making various design changes, increasing armor and strengthening weapons. So, the frontal armor of the "Panzer III Ausf.H" was already brought up to 60mm. For the late 30s, early 40s, it was a very good anti-shell armor. Work on the tank
continued during the first major victories of the Wehrmacht in the West, and then during the war with the Soviet Union, where the "Panzer III" was already the main tank of the German army. The combat value of the "Pz.III" of the most massive productions can be compared with the Soviet medium tank "T-28" in terms of firepower and armor, since after the Finnish war the 30-mm armor of these Soviet tanks was brought up to 50-80mm. Light tanks of the Red Army, such as the T-26 and BT-7, could fight the Pz.III on equal terms only under very favorable conditions, such as sudden fire from an ambush from a very close range, but as a rule, the trio outnumbered the light Soviet tanks at the expense of the best performance characteristics, primarily armor and guns, and also thanks to excellent guidance devices, excellent optics and the division of duties of crew members of five people, each of whom went about his own business, while, for example, Soviet crews of three on the T-26 were overloaded work. Comfortable conditions the work of the crew increased seriously increased the effectiveness of the "Pz.III" in battle. And yet, with all its advantages, the troika could not fight absolutely on an equal footing with the new types of Soviet combat vehicles - the T-34 and KV. Only at a very close range was the fire of the "Pz.III" cannon on these tanks effective - a weak gun at that time became the most serious drawback of this excellent combat vehicle. Soviet tanks, on the other hand, had the ability to penetrate Panzer III armor while being at a sufficiently large distance outside the effective zone of destruction of the latter. The only thing that prevented Soviet tankers from fully realizing their advantages in battle was the lack of radio communications, problems with the transmission of the T-34 and especially the KV, as well as poor visibility from the tank. In this, the "troika" had advantages, but these shortcomings on the "T-34" were eliminated during the war, which completely reduced some of the superiority of the "Pz.III" to nothing. The "Panzer III" was assigned the role of the main tank in the Eastern Campaign of 1941, and an unpleasant surprise for the Germans was its poor maneuverability in the conditions of the war against the USSR - too wide caterpillar tracks made it difficult for the tank to move along the Russian impassability. The commander of the third German tank group, Herman Goth, noted that the lack of roads prevented the advance of his tanks, which moved through Belarus to Moscow, almost more than the Soviet armies.
Assessing the latest modifications of the "Panzer III" tank, namely "Ausf.J", "Ausf.L" and "Ausf.M", it is worth saying that in the late 30s, early 40s it would have been just an excellent tank, however at the time of the deployment of truly mass production of these tanks of the latest series, Germany's opponents already also possessed good samples armored vehicles, in no way inferior, and in a number of characteristics even superior to the German tank. The British could oppose the German Pz.III with their Matilda with 78mm frontal armor, as well as the well-armored Valentine infantry tank. The Soviet Union mass-produced T-34 medium tanks, and the Americans began sending M4 Sherman tanks to their allies under Lend-Lease. The ultimate potential of the Panzer III design was achieved when the L and M modifications were developed. It was not possible to further strengthen the armor and install a more powerful gun on the Troika. The Soviet Union, Britain and the United States continued to improve the characteristics of their combat vehicles and it was no longer possible to hold out the "Panzer III" to their level. By that time, Germany had long ago had a more advanced tank - the "Panzer IV", on which it was finally finally decided to bet after the obvious impossibility of further modernization of the "Panzer III".

Official designation: Pz.Kpfw.III
Alternative notation:
Started work: 1939
Year of construction of the first prototype: 1940
Completion stage: three prototypes built.

The history of the medium tank Pz.Kpfw.III began in February 1934, when the Panzerwaffe had already entered the phase of actively filling their armored fleet with new types of military equipment. Then no one could have imagined how successful and eventful the career of the famous “troika” would be.

And it all started quite prosaically. As soon as the light tanks Pz.Kpfw.I and Pz.Kpfw.II were put into mass production, representatives of the Armaments Service of the Ground Forces formulated requirements for a combat vehicle of the type ZW (Zurführerwagen)- that is, a tank for company commanders. The specification stated that the new 15-ton tank should be equipped with a 37 mm gun and 15 mm armor. The development was carried out on a competitive basis and in total 4 companies took part in it: MAN, Rheimetall-Borsig, Krupp and Daimler-Benz. It was also planned to use a Maybach HL 100 engine with a power of 300 hp, an SSG 75 transmission from Zahnradfabrik Friedrichshafen, a Wilson-Cletrac type turning mechanism and Kgs.65/326/100 tracks.

In the summer of 1934, the Ordnance Department issued orders for the manufacture of prototypes, distributing orders among four firms. Daimler-Benz and MAN were to produce chassis prototypes (two and one sample, respectively). At the same time, Krupp and Rheinmetall were ordered to provide a similar number of towers.
The Armaments Directorate gave its preference not to the Krupp machine, which later became known under the designation MKA, but to the Daimler-Benz project. Although this decision then looked somewhat controversial, because the prototype from Krupp was built back in August 1934. However, after testing the chassis Z.W.1 and Z.W.2 Daimler-Benz received an order for the delivery of two more improved prototypes under the designations Z.W.3 and Z.W.4.

The new tank, developed by Daimler-Benz engineers, could rather be attributed to the light class. The first option, designated Vs.Kfz.619(experimental machine No. 619), in fact, was a pre-production machine, on which numerous innovations were tested. Undoubtedly, it favorably differed from the "ones" and "twos" with more powerful weapons and the best conditions crew work (due to a more massive hull), but then the combat value of the "troika" was not estimated as highly.

The design was based on a completely new chassis of the original configuration. Applied to one side, it consisted of five dual track rollers with coil spring suspension, two small support rollers, a front drive wheel and a rear guide wheel. The small-scale caterpillar consisted of steel single-ridge tracks.

The hull of the tank was designed with the expectation of a more spacious fighting compartment and the installation of a powerful engine capable of providing the required driving performance. At the same time, German designers actually abandoned the practice of installing armor plates at rational angles of inclination, preferring the best manufacturability of the design.

The layout of the case was close to the classical one. In front of the mechanical transmission was located, which included a 5-speed gearbox, a planetary rotation mechanism and final drives. To service its units, two large rectangular hatches were made in the upper armor plate.

The transmission included a five-speed Zahnradfabrik ZF SGF 75 synchronized mechanical gearbox. The torque from the gearbox was transmitted to the planetary turning mechanisms and final drives. The engine was connected to the gearbox by a cardan shaft passing under the floor of the fighting compartment.

Behind the transmission compartment placed places for the driver (left) and gunner-radio operator (right). The middle part of the hull was occupied by a fighting compartment, on the roof of which a hexagonal three-man tower with an upper inclined armor plate was installed. Inside it were places for the commander, gunner and loader. In the rear of the tower, a high observation tower was installed with six viewing slots and an upper double-leaf hatch. In addition, a periscope device was installed on the roof of the tower, and there were viewing slots with armored glass on the sides.

In general, starting with the "troika", the Germans paid great attention not only to good visibility, but also to ways to leave the tank in emergency situations - in total, the tower received three hatches: one upper and two onboard. At the same time, on the prototype and tanks of the first modifications, there were no hatches for the driver and gunner-radio operator.

In the aft part of the hull was the engine compartment. A Maybach HL108TR 12-cylinder V-shaped gasoline engine was installed here, which developed a power of 250 hp. at 3000 rpm. The cooling system is liquid.

The armament of the tank consisted of one 37 mm 3.7 cm KwK cannon with a barrel length of 46.5 calibers. According to the tabular values, an armor-piercing projectile 3.7cm Pzgr weighing 815 grams developed an initial speed of 1020 m / s and could penetrate a vertically mounted armor sheet 34 mm thick at a distance of up to 500 meters. But in fact, the armor penetration of 37-mm shells turned out to be much lower, which subsequently forced German designers to constantly look for ways to strengthen weapons. Additional small arms consisted of three 7.92 mm MG34 machine guns. Two of them were mounted in a mask to the right of the gun, and the third was in the frontal hull plate. Ammunition for the 37-mm gun was 120 armor-piercing and high-explosive fragmentation rounds, as well as 4425 cartridges for machine guns.

The first order for 25 "zero series" tanks was issued in December of 1935. At the same time, it was planned to start deliveries from October 1936, so that by April 1, 1937 the entire batch would be transferred to the troops.

After a relatively successful trial on April 3, 1936, the tank received the official designation Panzerkampfwagen III (Pz.Kpfw.III), while according to the end-to-end notation adopted in the Wehrmacht, it was designated as Sd.Kfz.141.

A total of 10 tanks of this modification were produced, which bore the original designation 1.Serie/Z.W.(subsequently) and were the development of Z.W.1. Due to the tight deadlines, a number of temporary measures and solutions had to be taken, which did not allow them to be considered full-fledged combat vehicles. As a result, two tanks had non-armored steel hulls. In addition, the armor protection of the first tanks was too modest. The forehead, sides and stern (both hull and turret) had a thickness of only 14.5 mm, the roof - 10 mm, the bottom - 4 mm. Soviet light tanks T-26 and BT-7 of the 1936-1937 model had similar performance, with more powerful cannon armament.

Almost all built Ausf.As were distributed between the 1st, 2nd and 3rd Panzer Divisions, where they were used primarily for crew training. In the winter of 1937-1938. they participated in large winter maneuvers of the Wehrmacht and showed themselves on the good side. Of the significant defects, only an unsuccessful suspension design was noted, which was corrected on other modifications of the tank.

The first combat operation involving the Pz.Kpfw.III Ausf.A was the Anschluss of Austria and the annexation of the Sudetenland in the spring of 1938. Several tanks in September 1939 were involved in the invasion of Poland, although this was, for the most part, a forced measure, since the tank regiments and divisions had to be completed to the maximum.

In addition, the units of the power plant were improved, primarily the turning mechanism and final drives. Other improvements included a redesign of the power compartment vents and exhaust system. At the same time, a new type of commander's turret was introduced, the same as on the Pz.Kpfw.IV Ausf.A tank, and five smoke bombs could be mounted in special pockets in the stern. The antenna mount was also moved a little further aft. In total, the improvements carried out made it possible to increase the maximum speed to 35 km / h, although the combat weight increased to 15.9 tons. Deliveries of tanks Pz.Kpfw.III Ausf. In the army began from mid-1937 to January 1938. The next batch of 15 tanks of the “zero series”, with chassis numbers from 60201 to 60215, was called 2.Serie/Z.W.(subsequently Pz.Kpfw.III Ausf.B) and was a development of the prototype Z.W.3. The main difference of this modification was the new chassis, instead of the five-roller one on vertical springs that did not justify itself. Apparently, Daimler-Benz engineers decided to carry out a kind of unification of the individual elements of the Pz.Kpfw.III and the future Pz.Kpfw.IV - now there were eight road wheels on each side, which were blocked in pairs into carts. Each of the carts was suspended on two groups of leaf springs and equipped with hydraulic shock absorbers of the Fichtel und Sachs type. At the same time, the design of the driving and steering wheels remained the same. The upper part of the caterpillar was now supported by three support rollers. The length of the bearing surface of each of the caterpillar chains was reduced from 3400 to 3200 mm.

Modification 3.Serie/Z.W, which became better known under the designation , was also released in an amount of 15 copies. The differences from Ausf.B were minimal - in fact, an attempt was made to modernize undercarriage. The first and last bogies had short parallel springs, while the second and third had one common long spring. In addition, the design of the exhaust system was changed, the arrangement of planetary turning mechanisms, and a new type of tow hook was used. Another difference between the Ausf.C modification (as well as the Ausf.В) was the rounded hatches with hinges, which were located on the upper armor of the front of the hull and were intended for access to the steering. After all the modifications carried out, the mass of the tank was 16,000 kg. Ausf.C deliveries were carried out in parallel with Ausf.B until January 1938 inclusive /

In January 1938, the production of the last modification of the tank was launched ( 3b.Serie/Z.W), which still used a 16-roller chassis with leaf spring suspension. True, a new series of changes was made to its design: the front and rear springs were not installed in parallel, but at an angle. The list of other changes was no less impressive:

- New driving and steering wheels have been introduced;

- the shape of the stern and the armor of the power compartment have been improved (access hatches to the nodes are devoid of ventilation shutters);

— changed the shape of the stern;

— Modified side air intakes;

— modified front tow hooks;

— Rear tow hooks were installed in a new place;

- the capacity of the fuel tanks has been increased to 600 liters;

— Modified exhaust system;

- a new six-speed gearbox ZF SSG 76 has been introduced;

- the thickness of the hull and turret armor, in frontal and side projection, has been increased to 30 mm;

- the design of the commander's cupola has been changed (the wall thickness has been increased to 30 mm, the number of viewing slots has been reduced to five).

Thus, Ausf.D became a kind of prototype for many of the following modifications. All the improvements made have a positive effect on specifications, but the combat weight of the tank increased to 19800 kg. Apparently, in order to speed up production, several of the first tanks did not wait for 30-mm armor rolling and their hulls were made of 14.5 mm thick armor.

In practice, the introduction of a 16-roller chassis did not change anything for the better. In addition, the weak armor of the first modifications of the Pz.Kpfw.III was indicated. Not surprisingly, after the Polish campaign, it was decided to withdraw Ausf.B, C and D from the combat units. This process was completed in February 1940.

The tanks were transferred to training units, but after some time they were again in demand. Ausf.D modification tanks had a chance to take part in the Norwegian campaign as part of the 40th tank battalion, and in October 1940, five Ausf.B served as prototypes for self-propelled unit Sturmgeschutz III.

In 1936, Daimler-Benz developed medium tank T-3, which went into production in 1938 (combat weight 19.5 tons, speed 40 km / h, armament - 37mm semi-automatic cannon, 3 machine guns, hull and turret armor - 30 mm).

After the 1940 campaign, Hitler demanded that the T-3 tanks be re-armed with a long-barreled 50 mm cannon. This was a tribute to the thick armor of the English Matildas. But the weapons department arbitrarily installed a 42-caliber cannon with a low muzzle velocity on the tank (modifications F, G and H - the main tanks of the German army in 1941).

In the battles on the Soviet-German front, the weakness of the armament and armor of the T-3 was revealed. The attempts made to modernize the T-3 in order to equalize its combat qualities with the T-34 did not give the desired results. Using the screening method in 1941, the thickness of the frontal parts of the hull was increased to 60 - 70 mm.

Tanks of modification J (from December 1941) finally received a 50-mm cannon with a length of 60 calibers. Its armor-piercing projectile (muzzle velocity 835 m/s) pierced 75 mm, and the sub-caliber (1130 m/s) 115 mm armor at a distance of 500 m.

The last vehicles of modifications M and N were armed with the same short-barreled 75-mm gun that the T-4 tank used to have (660 of them were produced in 1942-1943). In 1943, 100 flamethrower tanks were produced on the basis of the T-3, which participated in the Battle of Kursk.

The T-3 tank was a good vehicle from a technical point of view. Many innovations have found application on it: individual torsion bar suspension of road wheels, control using servo drives and planetary turning mechanisms, etc. However, the high specific pressure on the ground and the low specific power were the cause of insufficient mobility and low cross-country ability.

These characteristics were not improved during the modernization of the tank, since the same 300-horsepower engine was installed on the tanks, and the mass grew from modification to modification. Since the tank had no design reserves for a major modification, in August 1943 its production (after the production of 5,700 vehicles of twelve modifications) ceased. The freed-up factory facilities switched to the production of assault guns based on the T-3.

The history of the creation of the tank

By the mid 30s. Wehrmacht command came to the final conclusion that the Third Reich needed two main types of tanks - light and medium. At the same time, the base of the armored forces was to be made up of light, maneuverable tanks armed with a 20-mm gun. Heavier and slower vehicles, protected by thicker armor, were assigned the role of the main force in close combat. It was assumed that light tanks would fight enemy military equipment and be used for reconnaissance purposes, while medium vehicles would focus on the task of destroying enemy anti-tank weapons in depth. However, the very first experience of hostilities made significant adjustments to these calculations. Firstly, the German light tanks that existed at that time did not justify the hopes placed on them. Weak armor and poor armament made these vehicles absolutely unsuitable for the role of the Wehrmacht's strike force. Secondly, none of the German tanks that existed at that time could claim to be a full-fledged medium tank.

On the agenda was the question of the immediate creation of a fundamentally new combat vehicle that would combine maneuverability light tank with enhanced armor protection and combat power of the medium. The new tank needed a gun capable of hitting most enemy combat vehicles and anti-tank guns. According to the plan of Heinz Guderian, the chief of staff of the inspection of the armored forces, a 50-mm long-barreled gun could become such a weapon, but the Armaments Directorate of the Ground Forces, referring to the accepted standards for infantry anti-tank guns, insisted on maintaining the 37-mm caliber. All Guderian's attempts to convince the command that the defeat of the thick armor of enemy vehicles required much more powerful weapons were in vain - the "father of German tanks" had to give in. The only thing he managed to insist on was to increase the radius of the turret. Thus, the basis for the future equipping of the tank with more powerful weapons was preserved.

It was also decided that the new medium tank (which from 1936 became known as the Zugfuhrerswagen - the platoon commander's fighting vehicle) (later this vehicle received a new name - the PzKpfw III medium tank) in all main parameters should resemble the heavier tank of the battalion commander ( Bataillonfuhrerswagen). This meant that the tank was originally designed for a five-man crew (commander, turret gunner, loader, driver, and radio operator serving the course machine gun). The commander was placed between the shooter and the loader in the tower, his place was slightly raised and equipped with battlefield observation devices. Communication with the rest of the crew was carried out using a special microphone connected to the tank radio.

In 1935, after the development of the basic project, the military-industrial concerns Friedrich Krupp AG, * Rheinmetall-Borsig, MAN, Daimler-Benz received an order for the production of a prototype of the future medium tank. A year later, according to the test results, a special commission selected the project of Daimler-Beitz AG / In 1936, the first modification of the new tank appeared - SdKfz 141 (PzKpfw III Ausf A) or 1 / ZW (Zugfuhrerswagen - platoon commander's vehicle). In the period between 1936 - 1937. Daimler-Benz AG produces 10 experimental tanks of this modification. "According to domestic sources. in 1936-1937, Daimler-Benz produced 15 tanks PzKpfw 111 AusF A of the so-called zero series. Panzer III. History of creation and application. M. Eastern Front. 1995.

The armament of the new combat vehicle consisted of the same 37-mm KwK L / 46.5 cannon and three machine guns - with two twin MG-34s located in the turret, and the third in the hull. If the design of the hull and turret as a whole remained unchanged, then the design of the chassis had a number of significant differences from previous models. The undercarriage (on one side) consisted of five double road wheels of large diameter, cast drive wheels were in the front of the hull, and guide wheels (sloths) with a caterpillar tension mechanism were in the rear. From above, the caterpillar lay on two supporting rollers. The Maybach HL 108 TR engine allowed the 15.4-ton tank to reach speeds of up to 32 km/h. The thickness of bulletproof armor did not exceed 15 mm. In 1936, these tanks were transferred to military trials in the 1st, 2nd and 3rd tank divisions, as a result of which they were rejected.

The second experimental batch consisted of 15 units and was produced by Daimler-Benz A G in 1937.

These tanks received the designation 2/ZW, or PzKpfw III B. They had a completely new suspension, this time consisting of 8 twin small road wheels (on board), grouped two by two into carts, sprung by two semi-elliptical springs. At the same time, the number of support rollers increased to three. The new undercarriage allowed the tank to develop a high speed - up to 35 km / h. Like the Ausf A tanks, these experimental "troikas" were tested in Poland, and in 1940 they ended their service in the army forever. PzKpfw III Ausf B were withdrawn from the line regiments and transferred to training tank units of the Wehrmacht.

On the next 15 experimental tanks 3/ZW, or PzKpfw III C, the chassis remained the same, but the suspension was significantly improved. Now eight road wheels were interlocked in pairs into four bogies, each of which was suspended on three semi-elliptical leaf springs. The first and last bogies had short parallel springs, while the second and third had one common long spring. In addition, the design of the exhaust system, the device of planetary rotation mechanisms was changed. Despite all the improvements, this tank also suffered the fate of its predecessors - all 15 Ausf C triples were withdrawn from tank units before the war with France.

The fourth experimental batch of Ausf D (3b / ZW) tanks consisted of 30 units ("According to domestic sources, Daimler-Benz produced 50 PzKpfw III Ausf D medium tanks in 1038. See The Forgotten Troika". M., 1994, PzKpfw III Ausf D differed from model C in that the small springs of the first and last bogies were installed with a certain slope, which made it possible to slightly increase their efficiency when driving along the armor of the hull and turret was also strengthened to 30 mm.In 1938, these tanks entered service with parts of the armored forces, managed to fight in Poland, after which they were transferred to tank schools as training vehicles. However, several combat "triples" Ausf D stayed in the army a little longer and took part in the occupation of Denmark and Norway as part of the 40th tank battalion.

The PzKpfw III E became the first model of the "troika" launched into mass production. 96 combat vehicles of this modification received reinforced frontal armor (up to 30 mm), a more powerful engine (Maybach HI-120 TR) and an improved chassis design.
parts with six rubber-coated road wheels with torsion bar suspension and a new Variorex gearbox SRG 328-145. In addition, the design of the ball mount of the MG-34 - Kugelblande 30 course machine gun has changed, and the entrance hatches located on the sides of the tower have become double-leaf. Thanks to these changes, the combat weight of the new medium tank reached 19.5 tons.
In September 1939, after military trials, the PzKpfw III tank of this modification was finally approved and recommended for mass production. At the same time, inspectors from the Army Ordnance Department had to make sure that Guderian's doubts about the 37-mm gun were fully justified - this gun turned out to be too weak to deal with heavy enemy tanks. I had to urgently switch to equipping the “triples” with 50-mm guns, sacrificing a third machine gun. Since the creation of a large-caliber tank gun took some time, the first PzKpfw III Ausf F tanks continued to be equipped with 37 mm guns, and only the last quarter of the 435 combat vehicles were armed with 50 mm 5 cm KwK 38 L / 42 guns. In addition, the manufacturers managed to convert some ready-made Ausf E and F triples to the new 50 mm KwK 39 L/60 tank gun.

At the same time, seven large tank-building enterprises - MAN, Daimler-Benz. Alkett, Henschel, Wegmann, MNH, MIAG received a government order for the production of 600 advanced Ausf G tanks. On these tanks, the thickness of the rear armor for the first time reached 30 mm, and later copies were equipped with an additional commander's turret, the same type as the turret of the PzKpfw IV medium tank.
In October 1940, mass production of Ausf IL triples was launched. These tanks had an improved turret design with enhanced armor protection, which greatly increased the weight of the tank, which, in turn, required radical changes in the transmission. The frontal armor of the hull and turret box of the tank was additionally reinforced with an armor plate 30 mm thick, which made the turret virtually invulnerable to enemy guns. An additional shell box was often attached to the rear wall of the tower, which was jokingly called the “Rommel chest” by the troops. Due to the increase in the combat weight of the tank to 21.6 tons, it was necessary to use wider tracks (400 mm, despite the fact that the width of the tracks on the PzKpfw III Ausf E-G was 360 mm), and in order to reduce their sagging, the front support roller was shifted and slightly forward . Among other changes, one can note an additional corner profile installed at the base of the tower and protecting it from enemy projectiles.

Next serial version The “troika” was the PzKpfw III Ausf J (SdKfz 141/1) tank. Much more of these vehicles were produced than all the previous ones - 266 units for the period from March 1941 to July 1942. Initially, tanks of this modification were armed
KwK 38 L / 42 gun, but, starting from December 1941, according to Hitler’s personal order, they began to install a new 50-mm KwK 39 gun with a barrel length of 60 calibers. About 1,000 of these improved tanks were produced. The new "triples" had more powerful 50-mm armor, improved observation systems for the driver (the Fahrerschklappc 50 viewing device and the KFF 2 binocular periscope) and a new type of installation of the MG-34 turret machine gun. The combat weight of the new tank was 21.5 tons.
From the second half of 1942, the production of PzKpfw III Ausf L tanks begins. In the period from June to December of this year, 650 such combat vehicles were created. Compared to the previous versions, the new tanks had enhanced forehead and hull armor, which were protected by additional 20 mm armor plates. In addition, the armor of the mantlet of the 50 mm KwK 39 tank gun was increased. All these changes significantly affected the mass of the tank, weighing it down by another 200 kg. Medium tanks PzKpfw III Ausf L were used to equip the tank regiments of the mobile divisions of the SS "Adolf Hitler", "Reich", "Dead Head", as well as the elite division "Grossdeutschland".

The last version of the "troika" with a 50-mm KwK 39 cannon was the Ausf M. The tanks of this model had minor differences from the previous model and were produced from October 1942 to February 1943. The initial order for this tank was 1000 units, but since At this point, the undeniable advantages of the new Soviet medium tanks over all German PzKpfw IIIs became obvious, and the order was reduced to 250 units. 100 new "triples" produced by MIAG had to be hastily transferred under a special order to the Wegmann plant for conversion into flamethrowing tanks and assault guns.
Tanks of the latest production model received the designation assault tank PzKpfw-III Ausf N (SdKfz 141/2). The production of these combat vehicles began in June 1942, but by that time it became clear that even an improved version of the old "troika" could not compete with the new ones. Soviet tanks. The Wehrmacht needed no longer a partial modernization of old machines, but the creation of a fundamentally new version. By this moment, a new heavy tank PzKpfw IV appears, which becomes the main offensive weapon of the armored forces. Under these conditions, the PzKpfw III Ausf N tanks are assigned a supporting role, so their armament was the 75-mm KwK 37 L / 24 short-barreled gun used on the PzKpfw IV Ausf A-F1 tanks. A total of 663 PzKpfw III Ausf N tanks were produced with a combat weight of 23 tons.

For a good example of the suspension of the PzKpfw III tank and their differences.

Description of the design of the tank PzKpfw III

“PzKpfw III is a cruiser-type tank. The combat weight is about 22 tons, the armament at the moment consists of a long-barreled 50 mm cannon (50 mm KwK L / 60) and an MG-34 machine gun coaxial with it, located in the turret, and another MG-34, installed in the right frontal tank parts. In addition, the tank has machine guns (submachine guns), hand grenades, a signal pistol, and each crew member is armed with a personal pistol.

The front of the tank

The interior of the tank is divided into three compartments. The front one is intended for the driver, it is located on the left side of the body, exactly opposite the control levers and foot pedals. The gearbox is located directly under the dashboard, the brake is to the left of the driver. Steering and brakes hydraulic or mechanical.

The driver has at his disposal a viewing slot made of triplex glass block, protected by an armored cover. With a closed viewing slot, the driver can use two observation devices installed in specially drilled holes in the frontal armor. If the driver uses a regular viewing slot, these two devices are closed from the inside with a special cover.

Behind the left shoulder of the driver is another viewing slot, covered with armored glass that can be easily removed if necessary.

In addition to the driver, on the right side of the control compartment there is a place for a gunner-radio operator. At his disposal was a course machine gun MG, mounted in a ball bearing.

The observation slot and the telescopic sight are installed in such a way that as soon as the shooter turns his head to point the machine gun, his gaze automatically concentrates on the center of the target.

The radio station is usually placed to the left of the radio operator, above the gearbox, but in some cases it is installed directly in front of the shooter, in a niche under the frontal slope of the hull.

Fighting compartment of the tank

The fighting compartment, limited by the turret body, is located in the center of the vehicle. There is no floor, the commander's and gunner's chairs are suspended from the inner wall of the tower. The seat for the loader is not provided, so he stands to the right of the turret gun and, like the rest of the crew members of the compartment, rotates with the turret as it rotates.

The shooter takes a place to the left of the 50-mm gun. Near it is a lever for manually turning the tower.

On the left side of the tower there is a special observation slot for the commander. The commander's seat is in the center of the turret, behind the gun. commander's cupola has six viewing slots with bulletproof bulletproof glass and armored covers. The hatch of the turret is double-leaf.

Near the loader, an auxiliary flywheel for manually turning the turret is provided, which allows, if necessary, to quickly rotate. Power steering is not provided.

The engine compartment of the tank PzKpfw III

The engine compartment is located in the center of the stern and is separated by a partition from the fighting compartment. The engine is located in the center of the compartment, the fuel tank and battery are located to the left and right of it.

Behind the engine are two radiators. The cardan shaft to the drive wheels is passed over the bottom of the tank, right under the "floor" of the fighting compartment. There are evacuation hatches on each side of the hull.

The commander and gunner in the fighting compartment are provided with special means for orienting and aiming guns, and the driver for this purpose is served by his own gyrocompass.

Radio equipment of the tank PzKpfw III

It is worth noting that German tanks, unlike the famous T-34s, were overwhelmingly equipped with radio stations, which gave a huge advantage for conducting combat operations as part of armored units. The standard radio equipment of medium tanks PzKpfw III was the FuG 5 transceiver, which consisted of two receivers and one transmitter. The radio station was located in the tower, in the fighting compartment of the tank. Both receivers were mounted to the left of the gunner - radio operator, above the gearbox.

The receiver was directly in front of the radio operator. All external contacts were grounded.

The radio station was powered by tank batteries. Of the five crew members, only the loader and the gunner remained without communication, although, starting with Ausf L triplets, tanks began to be equipped with a special intercom, with which the commander could give orders to the shooter. The other three crew members were supplied with a microphone and headphones, and the radio operator's headphones were somewhat different from the rest.

The commander did not have independent access to the radio and could not turn the radio on or off or tune in to the desired wave. All these operations were under the exclusive control of the radio operator. Communication between the commander and the radio operator was carried out by means of two signal lights - one was installed in the tower, and the second was next to the radio operator.

The bulbs were lit using two multi-colored (red and green) buttons. Subsequently, this complex system was replaced by a simpler and more efficient one.

Command tanks PzKpfw III

Command tanks (Pcmzer-befeblswageti) based on the PzKpfw III - a total of approximately 220 command tanks were produced based on the Ausf D, E, and H triples. These tanks had a fixed turret, a gun dummy to mislead the enemy, and a large a frame-type radio station mounted in the stern.

The tanks, called Panzerbefehlswagen III Ausf D1 (Зс / ZW), were produced in 3 versions - SdKfz 266, SdKfz 267 and SdKfz 268, which differed from each other in radio equipment.

However, these tanks did not take root among the troops, since the lack of a tank gun made the officers practically unarmed in front of the enemy.

They had to rely only on service weapons, which made command tanks a very ineffective tool. With these requirements in mind, two more command tanks with reinforced armor and a rotating turret were created.

The first batch of such Panzerbefehlswagen III tanks, armed with a 50-mm KwK L / 42 cannon, consisted of 81 vehicles, then another 104 tanks were produced.

They were followed by another 50 command vehicles armed with a 50mm KwK 39 L/60 cannon (these tanks are known as Pz Bfwg III Ausf K. with 5cm Kwk 39 L/60).

The large loop antenna was replaced with a simpler one, making the tank less visible and therefore less vulnerable on the battlefield.

Retired colonel German Rott at one time commanded the 5th tank regiment and was well acquainted with the commander's tank based on the "troika". Here is what he wrote about this car:

“The first commander’s “troikas” appeared at the headquarters of our regiment not earlier than the spring of 1941. These tanks, equipped with wooden mock-up guns and powerful antennas, were designed for five crew members - a commander, a communications officer, two radio operators and a driver. Outside, tin containers were installed on the armor for our personal belongings. Unfortunately, on the very first day of the invasion of the territory of the Soviet Union, our command tank was disabled by a direct hit in the engine compartment.

He caught fire. We managed to get out of the burning car and moved into a light reconnaissance tank, but the rumor about our death spread throughout the regiment. There is a sign that a soldier who is mistakenly declared dead will live to the very end of the war ... Apparently, this is the way it is. At least all five of us survived."

Combat use of tanks PzKpfw III

In the period 1935 to 1945, 15,350 chassis were produced for the PzKpfw III tank (originally called ZW - platoon commander's vehicle).

The first * triplets *. 98 vehicles thrown into Poland became those who took part in the hostilities. Of course, at that time they were only a small part of the huge force thrown to conquer the eastern neighbor of the Third Reich. According to domestic sources, in May 1940, the German army had 381 PzKpfw III tanks on the Western Front. Ausf A-E. However, already during the hostilities in France and the Netherlands, the total number of PzKpfw III in active units increased to 349 units "and continued to grow steadily. Since by this time the "ones" and "twos" had long exhausted their resources, and the few medium tanks PzKpfw IV up to for the time being they were used only as infantry escort vehicles, the "troikas" had to take the place of the main striking force of the German 6-tank troops, the main fighting vehicle of the Wehrmacht. However, the design flaws of the new tank did not allow it to successfully meet such high expectations. In order to become a truly main A Wehrmacht fighting unit, the PzKpfw III required much thicker armor and more powerful weapons.

And yet PzKpfw III still managed to fight in North Africa and in Eastern Europe. As expected, by this time he had lost his dominant position in the troops, giving way to the main offensive force, first to the medium PzKpfw IV, and then to the Panthers PzKpfw V. By the time the Panthers appeared, the Troikas finally switched to the role of auxiliary support and escort tanks . Brian Perret, the author of a monograph on the PzKpfw III tanks, wrote about it this way: “In the finest hour of the blitzkrieg, the PzKpfw III tanks were main force and the stronghold of the power of the Wehrmacht, and their role can only be compared with the Napoleonic grenadiers. The Troikas were not just witnesses, but the true creators of military history - they made it on the bridgehead from the English Channel to the Volga, from the Arctic coast to the deserts of North Africa. It was the PzKpfw III that nearly made Adolf Hitler's worst dreams come true."

Leaving the arctic snows alone, let's turn to the desert sands. There is a lot of evidence of the superiority of the firepower of the "triples" over the tanks of Germany's opponents. As you know, initially the Allies had no doubt that their rapid-fire 2-pounder gun and the American 37-mm anti-tank gun were far superior to the 50-mm guns of the Nazi "troikas".



Tutorials for Soviet soldiers to destroy T-III tanks

Even Liddell Hart himself, the author of an excellent monograph on the Second World War, at one time was convinced of the superiority of British armored vehicles. His conclusions, based on very convincing figures, were included in a fundamental British study on the fighting in North Africa in 1941-1943. It is characteristic, however, that in the corrected and supplemented edition of the same work, all the figures and conclusions of Sir Basil regarding the German "triples" were radically revised.

The new edition unequivocally proves the superiority of the PzKpfw III tanks, armed with long-barreled 50 mm KwK 39 L/60 tank guns. British generals, as well as later British military historians, were misled by the thesis about the fundamental superiority of their tank guns over any armor of German tanks. However, the authors of this thesis did not take into account the fact that since the end of 1941 the Germans have significantly strengthened the armor of their "triples". The frontal armor of the PzKpfw III, reinforced with additional armor plates, could easily withstand the fire of both British and American anti-tank guns(Of course, with the exception of a direct hit at close range). The British designers and military experts, until the very last moment, were convinced that the guns of their tanks were capable of turning any German vehicle into ruins, but this was not so.

Let us now turn to the testimonies of eyewitnesses. This time I want to give the floor to Major (later Colonel) of the American Army George B. Jarrett, who arrived in the Middle East in February 1942 and had a unique opportunity to get to know all the Allied and German tanks that existed at that time. According to Jarot , both British and American anti-tank guns were absolutely helpless against the armor of the German "triples" and "fours", while both of these tanks, armed with 50- and 75-mm KwK guns, easily disabled all combat vehicles allies, with the possible exception of the British infantry tank "Matilda". Jarrett claims that even at the maximum distance of 2000-3000 yards (1830-2743 m), German tank shells hit the tracks and undercarriage of the anti-fascist coalition tanks.

Of course, there were exceptions. One can imagine with what impatience the Americans, who landed in northern Tunisia at the end of 1942, were waiting for the first meeting with German troops. On November 26, 1942, several companies of the 1st Armored Division, which had at their disposal light tanks MZ "Stuart", surrounded six German PzKpfw IV and three PzKpfw III. “Having squeezed the enemy into a ring, the Stuarts, armed with 37-mm cannons, opened aimed fire on the sides and rear of the German tanks and disabled all the “fours” and one “troika” * ". However, the honesty of the official historian makes the author after the description brilliant victory to make the following addition: "However, we owed this victory solely to quantitative superiority and not to superiority in technology. "In addition, in this battle, the Allies lost 50% of their tanks. It was the number that ultimately determined the victory of the Allies in Northern Africa It is worth noting that the Allies often ambushed or hunted German vehicles.

The scale of Allied armor deployed to the African front grew steadily. A huge number of new American medium tanks MZ "Grant" and M4 "Sherman" put the Germans in a stalemate, despite the fact that somewhere in the middle of 1942 Rommel began to receive help from Germany. To Africa, in addition to the "tropical" PzKpfw III models. PzKprw III Ausf J were deployed, with enhanced armor protection and a long-barreled gun, and in mid-June several PzKpfw IVs with a new 75-mm KwK40 long-barreled gun were sent there. whose projectiles had a high muzzle velocity. "This gun was an ominous harbinger of the imminent appearance of the merciless Panther."

From the many memoirs of the crew members of the legendary "troika", I have chosen for this book the story of Eustace-Wilhelm Ockelhauser, cited in his book of military memoirs "Zogett in das Feld". I want to introduce you to an episode related to the combat path of the "troikas" in the Soviet Union.

“A new commander arrived in our company - a reservist, a teacher of the profession. The poor fellow was unlucky with growth - the dimensions of our tank were clearly small for him. First of all, the new commander ordered us to find and recapture a staff car with three officers, which went on reconnaissance and stumbled upon a Russian ambush. Judging by the radio signal we received, the car was somewhere outside the city. It was decided to send two tanks, but since the long lieutenant did not yet have his own car, he took command of tank No. 921. It just so happened that it turned out to be my tank.

I sent the loader away and took his place between the cannon and the shell box. Finally set off. Not even a quarter of an hour had passed since the moment we left our company, through a narrow observation slot I saw the disguised location of the Russian infantry. The Russians were only a few meters away from us in a small clearing. The lieutenant, apparently, did not notice the dark silhouettes of the foot soldiers and continued to serenely survey the surroundings, leaning out to the waist from his hatch. I hit him under the knees with all my strength and dragged him inside. "What's the matter, nerd?! Damn you!" he yelled, looking at me furiously. There was no time for an explanation. The next second, burning oil poured into the tower, and the poor lieutenant screamed wildly in pain. I knew well what it was. The Russians threw a "Molotov cocktail" into the open hatch ", and the burning mixture, flowing from the lieutenant's back and neck, poured into the tank.

My first move was to immediately jump out of the burning tower, but I knew perfectly well that the Ivans were just waiting to finish off the pass on the ground. Damn it! Frantically looking around, I suddenly saw a fire extinguisher attached to its bracket. I pulled it off the wall. Thank God! The fire extinguisher was full, although I can't remember the last time I saw such a miracle in a tank. I tore off the seal and directed the foaming jet into the flame.
At this time, Run, our gunner, with all his strength, held the legs of the idiot lieutenant, who howled in pain and tried to jump out of the tank. Finally, he lost consciousness and slid down helplessly. I thoroughly treated it with foam, extinguishing the remnants of the fire. Pushing the lieutenant's unconscious body with difficulty, I climbed into the commander's seat and immediately heard the roar of flames from above. Two grenades exploded at the stern, bullets pounded on the sides like a hail. Our tank was moving at top speed. I was completely unoriented and could not give any instructions to the driver, because something was lying on the tank's hull, blocking the viewing slots. The manhole covers were open. Damn that lieutenant! I always kept them closed. A cloudless summer sky floated overhead.

Rune handed me an object. I took a closer look and recognized the half-burned headphones of the lieutenant. Fortunately for us, the radio worked, and I heard the excited voice of Sergeant Major Reitz, the commander of the tank following us, in my headphones. "Stop!! he yelled. - 921, stop! Stop! Where are you going, damn you? Are you blind? It's full of Russians! We are in ambush. Turn around, but be careful. We have two Russians lying in front of the tower, and another one is sitting on the tower. Close the hatch immediately before he throws a grenade inside! Don't worry, I'll try to sleep them. Slowly turn around and let's go."

The situation was critical. The Russians sitting on the armor tightly blocked both viewing slots - both mine and the driver's. Our blinded tank was moving straight into the Russian position. Headphones worked, but I didn't have a microphone. Pushing the lieutenant, who was moaning in unconsciousness, I began to make my way into the compartment to the driver. Rune wasted no time either - I saw him shoot one machine gun belt for another. When I got to Logo, our driver, I tapped him on the left shoulder. He instantly realized what was happening and began to turn left. The roar of the engine drowned out any words, it was necessary to "talk" with the help of gestures. Suddenly, the view in front of the driver became free. I realized that the Russian blocking it had to hide behind the turret to escape the machine-gun fire that Reitz was spraying on our tank. The sergeant-major’s voice in the headphones dispelled the last doubts: “Great, guys! Take it cooler - take it easy, don’t rush. Now straight ahead. Don’t fly, otherwise you’ll run into. ".

Do it yourself ... At first I thought about the fans, but the danger that their fragments could get into the ventilation holes in the engine compartment made this option unacceptable. Finally came up with. He carefully removed the bulletproof glass from the viewing slot and fired a pistol at the dark mass blocking the opening. Two, three, four shots. Shot the whole clip. The dark mass stirred and froze. But I didn't have time to take a breath, as someone's body blocked the open hatch. It became completely dark in the tank. Right in front of my face, I saw first a sleeve, then a dirty palm, and then a brown shoulder and part of a head. What to do? The store is empty. I rushed down and yelled at the top of my lungs, "Run." The gunner did not hear, carried away by shooting. His eyes were glued to the optical sight. In desperation, I threw away my gun and grabbed my flare gun. Aimed up and fired. The rocket hissed out of the barrel. That was all... *I couldn't kill him, I thought. - He just got mad. Now he will take out his Molotov cocktail and throw it here ... Or he will use a couple hand grenades-". Preparing for the worst, I huddled in the farthest corner of the loader's position. I was shaking. The hatch was still dark, and death did not come. I don't remember how much time has passed. During his
jump, I lost my headphones and now I'm left without a connection. All that was heard was how the machine gun was pounding on our armor.
Suddenly someone pulled me by the leg. I turned around and saw the pale face of the radio operator right in front of me. He handed me a loaded gun. Thank God! I put my hand through the hatch again and squeezed the trigger. Now the damned Russian must free our hatch! Shot... Another one. Two more. No changes. The same darkness. And then the tank suddenly stopped. What else happened?! I got up and looked up. Warm blood dripped onto my face. The Russian was dead.
It didn't take me much effort to move it off the hatch. What a joy to see the sky above again!
The fire outside has subsided. I quickly stuck my head out of the turret and stared straight into the two black machine-gun barrels of the Reitz tank. It turns out that the tower of a hundred tanks was only three meters from ours! A dead Russian was lying on the stern, I myself threw the second from the tower. Damn it - next to him were two bottles of Molotov cocktails and a bunch of hand grenades! The third Russian disappeared without a trace. Reitz stepped back carefully and picked up his headphones, which meant that he wanted to contact us immediately. I climbed into the commander's seat, but awkwardly stepped on the chest of the lying lieutenant. Rhun was still on his machine gun, turning the turret around every now and then. I noticed that he managed to shoot another machine-gun belt into the forest. I shouted to the radio operator to look for my headphones, but he, of course, did not hear. I had to knock him on the back with an empty pistol. It worked - the radio operator finally turned around and guiltily handed me headphones and even a microphone. Finally, I can talk to Reitz!

The sergeant-major said that his tank was completely intact and ready to continue fulfilling the order. Unfortunately, I could not boast of the same and said that we must immediately return to the company's position, since the lieutenant needed urgent medical attention. Reitz agreed and we turned around in the opposite direction. Since I decided to bandage the lieutenant, I ordered my driver to simply follow the Reitz tank.

There was a terrible stench in the tower - it smelled of gunpowder, foam and burnt meat. When a quarter of an hour later we arrived at our own, I jumped out of the tank on the move and rushed into the bushes. I just turned inside out. There I lay, choking on vomiting, when our doctor, Rubenser, found me. Without saying a word, he left somewhere, then returned with a large pot in which we cooked food and heated water for washing. Doctor washed me cold water like a baby, and bandaged his burned hand. When he finished bandaging my burns, I forced a smile, but the doctor said: "The commander is waiting for you. Go, report on the results."

Karl was sitting between the tracks of the tank. There was a stretcher next to him. In a long body wrapped in white bandages, I recognized our lieutenant. I saluted and reported what had happened.

Why didn't you follow the order? I think you were sent to look for a staff car with officers? It's easier to turn back. If you ever want to be in command of a tank again, you will have to learn to follow orders no matter what the circumstances. It's time to get used to the fact that the execution of orders is always accompanied by difficulties. War cannot be like a ballroom dancing class.
- I obey, mister lieutenant!
- Are you seriously injured?
- No, sir lieutenant!
“In that case, you and Reitz will immediately go on a mission. Now you know where to look for a car. Try to follow orders this time.
- I obey, mister lieutenant! I saluted and turned around. Tears filled my eyes. God, why am I being sent back to hell again?!
Two tanks were already waiting for us. Reitz waved at me in greeting. I silently grabbed the muzzle of the gun and climbed into the hatch. The motor blew. I discreetly wiped my face with a bandaged hand and took a few deep breaths. It seems to have let go.^ Now I could get in touch with Reitz without shame.

What's with the radio? - the first thing he asked. Why is there a squelching noise in my headphones? I had no choice but to remain silent.

We returned to the same place. I gave the order to fire both machine guns. Pouring fire on the forest, we cautiously approached the place where our staff car was parked. There were no Russians around. Something gray was lying in front of the car ... nearby, in the grass, I saw a dead non-commissioned officer. We drove closer. Reitz climbed out of the tank, carefully approached the body, and turned him over on his back to remove the medallion. Then he looked at me and shrugged his shoulders in bewilderment. The officers disappeared without a trace. I carefully examined the dense greenery of the bushes through binoculars. Then I turned my gaze to the village and tried to put myself in the place of the officers. Where would I take cover if I were surrounded? Having chosen a suitable place with my eyes, I slowly sent my tank there. The way it is! All three lay in a shallow ditch. Dead. Colonel, major and boy lieutenant. We put the corpses on the hull and drove to the location of the unit.

I went to report, the rest took care of the dead. The commander was still there, near the tank. The stretcher with the lanky lieutenant disappeared - the poor fellow was transported to the central evacuation point. Carl listened to me in silence, without interrupting. When I finished, silence reigned ... I still remember his words:
- If you had carried out the order and had not returned halfway, these four would be alive now.
I had nothing to answer. The commander was right.
