T-24

The T-24 was a Soviet medium tank built in 1931. Only twenty-four were built, and none saw combat. This was the first tank produced at the KhPZ factory in Kharkov, which was later responsible for the very successful BT series, T-34 and T-54 Soviet tanks. The T-24's suspension was used successfully in the Soviet Union's first purpose-built artillery tractors.
The T-24's main armament was a 45 mm gun. It had a ball-mount 7.62 mm DT machine gun in the hull, another in the turret, and a third in a secondary turret atop the main turret. The tank was well-armoured for its time, but the engine and transmission had problems.
