The T-28 is a Soviet three-turret medium tank, developed and put into production in the pre-war period, which took part in active hostilities in a number of local wars and the initial stage of the Great Patriotic War. The T-28 tank was adopted by the Red Army in August 1933 and was produced at the Kirov plant in Leningrad until 1940. A feature of the T-28 was the presence of three rotating turrets with weapons. Despite its relatively heavy weight, the tank had good maneuverability. Captured T-28s were used by the Finnish troops, which remained in service until 1951.
