At the request of Terry here is a Russian Tank Poll

Huh? No BT2?
T-34
You are missing an interesting option; the US Sherman! The Soviets received THOUSANDS of M4A2 medium tanks - 75mm early hull, 75mm late hull, 76mm versions, and even the M4A2E8 with wide tracks. These were in many units all the way to Berlin and into Manchuria. You might be able to get Figarti interested in an M4A2. The diesel M4A2 was not a standard tank in US Army service but the 75mm version was used by the British, by the USMC, the Soviets and by the Free French.
