BT-7 is a Soviet light tank of the interwar period and the initial phase of World War II. The first prototypes of this car were created in the early 1930s, and serial production lasted from 1935 to 1940. In its course, probably about 5300-5500 cars of this type were created. In the basic version (BT-7), the drive was provided by one M-17T engine with a capacity of 450 hp. The main armament consisted of a 1932 model gun of 45 mm caliber and 1 DT machine gun of 7.62 mm caliber. The BT-7 belonged to the family of high-speed (high-speed) tanks developed in the USSR on the basis of imported chassis and chassis by Walter Christie. This allowed these tanks to move both on tracks and on wheels. Of course, when driving off-road, the maximum speed of BT family cars was very high - significantly exceeding the capabilities of tracked vehicles. The BT-7 tank also had this option. It was created as an evolutionary development of the BT-5 car. However, it had a larger body than its predecessor. Since 1937, a new tower was installed on it, the suspension was also strengthened and the transmission was improved. At the end of 1939, the BT-7M model went into production, equipped with a more powerful W-2 engine and a completely new turret. BT-7 tanks were used in combat during the aggression against Poland in September 1939, as well as at the initial stage of the German-Soviet war in 1941.
