The most numerous and famous tank in the world’s history was the Soviet T-34.
T-34 with 76,2 mm F-34 gun was the main Soviet medium tank up to the end of 1944.
In April 1944 the State Defense Committee decided on the creation and serial production of a tractor based on the T-34-76 tank. According to this order, the production of tractors based on the T-34 tank was to be launched at tank repair plants in the amount of 50 units per month. For the production of tractors, it was required to use the T-34 tanks coming in for major repairs with towers and weapons unsuitable for restoration.
