The Russian tanks were also superior to the Nazi Panzer tanks. As well, defeat was not an option for Russia, and Stalin knew that, and if he had to kill his own soldiers to defeat the Germans, then he was prepared to do so. And finally, Soviet tanks and soldiers greatly outnumbered the Germans, which was another major factor. In fact, Hitler once said "If I had known that they had 10 tanks for each of our tanks, I would have reconsidered invading the USSR." Well, that's not a direct quote, but he said something like that. The point is, the USSR defeated two thirds of the Nazi Army, and they were a major factor in the defeat of the Third Reich.
