tank #2 = IS-2….naaa release to late in the war to get a real impact.
I don’t know where on earth you guys are getting this: it’s simply not true! (Are you guys still confusing the IS-2 with the IS-3?) The KV series was off of the battlefied for the second half of the war, for the most part, and replaced by the IS-2! More IS-2’s were produced than either KV-1 or KV-2’s (or stop-gap measures such as the KV-85 for that matter) and the Soviet counter-offensive that really won the war on Germany was spearheaded by twice as many IS-2’s as Germany ever produced Tigers!
