The T-70 is a Soviet light tank from the Second World War. The first prototypes of this vehicle were built in 1941-1942, and serial production lasted from 1942 to 1943. About 8,250 vehicles of this type were created in its course. The weight of the tank in the basic version was up to 9.2 tons. In the basic version, the drive was provided by two GAZ-202 engines with a capacity of 70 HP each. The armament of the vehicle consisted of a 45 mm 20K wz.1938 gun and 1 DT 7.62 mm machine gun.
The T-70 light tank was developed as, in essence, a far-reaching modification of the T-60. The new vehicle mainly uses a completely new power unit, slightly lengthened the hull and the suspension of the tank was interfered with. The T-70 also had a new turret and improved armor. Cars of this type were manufactured mainly in plants located in the cities of Gorki, Kirowa and Sverdlovsk. One major modernization of the T-70 vehicle, designated as the T-70M, was completed. It was characterized by an improved chassis, the use of new tracks and the use of a larger number and better quality battlefield observation devices for the driver-mechanic and the vehicle commander. It is worth noting that the successful SU-76 and SU-76M self-propelled guns were created on the T-70 chassis.
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.
