The decisive influence on the shaping of the organization and tactics of the German infantry before the outbreak of World War II was, on the one hand, the experience of the previous World War, but also theoretical works created in the 1920s and 1930s, which often emphasized the need to perceive the German infantry as a tool waging an offensive war. This affected both the equipment and the organization of the German infantry division, which during the September campaign of 1939 consisted of 3 infantry regiments, each of which was divided into 3 infantry battalions, an artillery company and an anti-tank company. In addition, there were numerous support units, including: an artillery regiment with 4 artillery squadrons (including one heavy), an anti-tank battalion, a sapper battalion and a communications battalion. In total, the so-called infantry division In the first mobilization wave, there were approximately 17,700 people and had a significant artillery component, but also was abundantly equipped with machine guns. It also had modern and efficient - for those times - means of communication and command. In the course of the war, infantry divisions underwent transformation - in 1943 some of them were transformed into armored grenadier divisions. However, from 1943, the standard division of the "traditional" infantry consisted of approx. 12,500 men (and not approx. 17,700 as in 1939), and its artillery component - especially heavy artillery - was also reduced in it, while its anti-tank defense was significantly improved. It is assumed that during the entire Second World War, about 350 infantry divisions served in the Wehrmacht.
The T-34 was a Soviet medium tank from the Second World War and the post-war period.
The first prototypes were built in 1937-1940, and serial production in the USSR was carried out in 1940-1957. About 84,000 vehicles of this type were built in its course, which makes the T-34 one of the most produced tanks in history! The drive was provided by a single engine V-2-34 with a power of 500 hp. The length of the car - in the T34 / 76 version - was 6.68 m, with a width of 3 meters. The armament consisted of a 76.2 mm F-34 gun and two 7.62 mm DT machineguns. The main armament in the T-34/85 version was the 85mm ZIS-S-53 gun.
The T-34 is undoubtedly one of the most famous tanks in the history of both World War II and military in general, representing a specific symbol of Soviet victory in the war with the Third Reich. The vehicle was developed for the needs of the Red Army as a successor to the so-called pursuit tanks from the BT series (BT-5 and BT-7), but also the T-26 tank. Work on the car started in 1937 in a special design office at the Steam Engine Factory in Kharkiv. Initially, the works were managed by Eng. Adolf Dik (he also made the first sketches of the new car), and after his arrest by the Soviet security authorities, Mikhail Koszkin managed the work. Initially, the vehicle was designated as A-20. However, a second prototype (A-32) was quickly built, with a main armament in the form of a 76.2 mm cannon and much thicker frontal armor. It was the latter prototype that was finally adopted for production. It can be assumed that when it was introduced into service, the TT-34 was a very successful tank in many respects. It was characterized - as in 1940 - with a very strong weapon, it had a well-profiled armor based on sloped armor plates, as well as very high mobility and off-road driving properties. The disadvantages include the very poor ergonomics of the car or the poor optics used in the first production batches. Despite these shortcomings, when the T-34 appeared on the Eastern Front, German troops were greatly surprised by it. The high overall rating of the T-34 and its combat values determined its mass production and making it the basic tank of the Red Army during the fights in 1942-1945. They also resulted in further improvements to the structure, e.g. in 1942 a new hexagonal tower appeared, improving the quality of work of crew members with the commander's cupola. The engine and gearbox were also improved. However, in 1944, the T-34/85 model was introduced into service, with a completely new three-man turret and the main armament in the form of an 85 mm cannon. The T-34 tank fought in virtually all major battles fought between the Red Army and the Wehrmacht on the Eastern Front in 1941-1945: starting at the Battle of Moscow, through the battles of Stalingrad and Kursk, Operation Bagration, and the capture of Berlin. After 1945, the T-34 tank was still in service, it was also widely exported outside the USSR to countries such as Czechoslovakia, Poland, East Germany, Hungary and Syria.
The IS-2 is a Soviet heavy tank from the Second World War. The first prototypes of this vehicle were built in 1943, and it entered service in the same year. 3400-3600 vehicles of this type were manufactured in the course of production. The combat weight of the tank was up to 46 tons. The drive was provided by a single W-2-IS diesel engine with a power of up to 520 HP. The basic armament consisted of the 122 mm D-25T gun and 3-4 machine guns: 1 12.7 mm DSzK rifle and 2-3 7.62 mm DT rifles.
The IS-2 was developed as a development of the IS-1 tank, and the main difference between the two turrets was the use of a much more powerful armament in the IS-2, i.e. the 122mm gun. It allowed the IS-2 to engage in a fairly equal fight with the German PzKpfw vehicles. V and VI, as well as to effectively support the attack of own infantry. Already in the course of World War II, the basic version of the IS-2 was modernized, bearing the designation IS-2M, which was characterized by the use of, among others: a semi-automatic wedge lock, improving the rate of fire, as well as changing the front armor plates on the hull. The IS-2 tanks proved to be very useful heavy tanks with high combat value in the period 1943-1945. It is worth adding that they were formed almost exclusively into separate Guard heavy tank regiments.
The Pz.Kpfw VI (Sd.Kfz.181) Tiger is a German heavy tank from World War II, one of the most famous combat vehicles of that time. The command of the German Panzerwaffe had the idea of creating a heavy tank from the beginning of the war, but the first attempts in the form of the centuries-old Neubaufahrzeuge tank turned out to be unsuccessful. In 1939 and 1940 they were conducted ineffectively, but after the clash with the T-34 and KW-1 on the eastern front, work on the new heavy tank sped up. On April 20, 1942, the prototype of the new tank, under the designation VK 4501 (H), underwent field trials in the presence of Adolf Hitler and was put into mass production shortly after. The first production versions were designated Pz.Kpfw VI Ausf.H1 (later Ausf.E). In the course of production, in the years 1942-1945, the tank was systematically modified by, for example, adding Feifell dust filters, different placement of headlights, modernization of optical equipment, changes to the commander's turret, etc. The drive was provided by a Maybach HL230 P45 12-cylinder carburetor engine with a capacity of 700 HP. The Pz.Kpfw VI tank, although it did not have such a contoured front hull as the T-34 or Pantera, was a heavily armored vehicle (frontal armor up to 120mm), armed with a very effective KwK 36 L / 56 88mm gun, which earned the reputation of being the most effective tank of the Second World War. It was a vehicle much better than the Allied M4 or Churchill and the Soviet T-34/76. He could also easily fight the IS-2 or M-26, surpassing them with the effectiveness of the main armament. On the other hand, the Pz.Kpfw VI had some disadvantages - first of all, it was extremely time-consuming to produce and had a very complicated suspension. In the later period of the war, the quality of the Tiger's armor also deteriorated, which resulted from the lack of access to the molybdenum deposits by the German economy. Despite these drawbacks, the Tiger on the battlefields proved to be a very effective weapon. He successfully fought in Tunisia, the Kursk Arch, Normandy and on the Eastern Front. Technical data: length (with a barrel): 8.45m, width: 3.7m, height: 2.93m, engine power: 700KM, weight: 56.9 t, range (on the road): 100km, maximum speed (on the road) ): 38 km / h, armament: 1 88 mm KwK 36 L / 56 gun, 3 7.92 mm MG 34 machine guns.The ZIS-3 is a Soviet 76.2mm cannon known under the designation "76.2mm gun wz.1942". Although the gun entered service in 1941, it was officially entered in the Red Army in February 1942, hence the designation. Over 50,000 jobs were created in the course of serial production. pieces of this weapon, widely considered to be one of the best cannons in its class during the Second World War. The ZIS-3 served multiple functions: from supporting infantry operations, through counter-batter fire, to the role of an anti-tank gun. She did very well in all of them. For the first time on a large scale, the ZIS-3 was used in the Battle of Stalingrad (1942/1943). In 1942, a very effective sub-caliber ammunition was introduced, which was used on a mass scale near Kursk in 1943. The ZIS-3 was also used as a capture weapon by the Third Reich and Romania, which even launched the production of this gun after it had been recalibrated! The ZIS-3 was also the primary weapon of the SU-76 and SU-76M vehicles. Technical data: barrel length: 3169 mm, range: 13290 m, caliber: 76.2 mm, combat weight: 1200 kg, initial velocity: 680 m / s, rate of fire: 25 spins / min.
In the 1920s and - especially - in the 1930s, the Red Army underwent a rapid development in terms of increasing its posts, as well as increasing saturation with technical weapons, primarily armored weapons. Still, the infantry was the primary and numerically largest element of the Red Army. The intensive quantitative development of this type of weapon began at the turn of 1929/1930. In 1939, even before the aggression against Poland, the Soviet infantry was formed into 173 divisions (so-called rifle divisions), most of which were grouped in 43 corps. It is worth adding that after the September campaign in 1939, this number increased even more. The Soviet rifle division in 1941 consisted of three rifle regiments (three battalions each), an artillery regiment, after an anti-tank and anti-aircraft artillery division, as well as reconnaissance and communication battalions. In total, it numbered about 14,500 people. However, by 1945 this position underwent significant changes, leading to a division of approximately 11,500-12,000 people, consisting of three infantry regiments, an artillery brigade consisting of three regiments, a self-propelled artillery squadron and many support units, including anti-tank, anti-aircraft weapons or communications. The saturation of infantry units with machine weapons has also increased significantly - for example with the submachine guns APsZ 41, and later APsZ 43.
