Soviet Tank T-28 (Red Army)

"....The T-28 was the first Soviet medium tank to enter mass production. Designed between 1931 -- 1932. It's principal battlefield role was to support infantry and other ground troops against enemy strong points. The armament was housed in three turrets, following the then prevailing views amongst tank designers of the time, which favored the multi-turret concept. The main turret was armed with the KT-28 (76.2 mm) gun, which was specifically designed for this tank to devastate enemy strong points and armor. The two remaining small turrets were each armed with a DT (7.62 mm) machine-gun which was used mainly against infantry and light-armor.

The production line was located in the Kirov factory, Leningrad and the tank was produced in several series from 1938 onwards. The new L-10 (76.2 mm) long barrel gun became the standard armament later. All in all, a total of 503 tanks were built between 1938 -- 1940.

The T-28 passed its first baptism of fire during the Winter War, between the USSR and Finland. It was also used on all fronts during the first two years of WWII. In the Soviet Union, its last reported action was in helping to break the blockade of Leningrad during the winter of 1943 --1944. .....""
