NOTES
1Soviet nomenclature is unclear. These Desig­nations are usually found in references to the vehicle specified here. However, there was also a postwar modernization of the IS-2 which the Soviets formally designated the IS-2M.
2This is an estimate of IS-2 Model 1944 production during the noted production period. Production continued after this period. Higher estimates seem to include IS-1 and early IS-2 production.
3It is assumed here that three 90 liter tanks are used for fuel.
