IS-2 Joseph Stalin Heavy Tank

The IS-2 Stalin was a development of the basic KV heavy tank with the same engine as the KV but with the idlers, sprockets and rollers lowered to allow the superstructure to overhang the chassis and allow for a larger turret. This larger turret housed a 122mm gun which was upgunned from the original IS-1A and IS-1B with 85mm and 100mm guns respectively.
