T-26-4 Artillery Tank
The T-26 light tank was the Soviet version of the Vickers 6-ton tank. The final model T-26 had a 45 mm gun and a 7.62mm MG although there were many other conversions.
Following the modification of the T-26 with the A43 turret and a 76mm gun, the T-26-4 was developed in 1932. It featured a larger turret and was fitted with a KT cannon and one or two DT machine guns. The same turret design was subsequently used in the BT-7A Artillery Tank.
