I was watching this video which makes a case that the major reason for poor Soviet performance in 1941, was its reorganization in the face of blitzkrieg 1939-1940. And so the Red Army was in a major state of flux and disorganization when the Nazis hit them.
Now in theory it made sense to reorganize towards more mechanized tank armies after the success of blitzkrieg. But given that it was not carried out in time, it probably ended up doing much more harm than good. So what if the USSR had kept their mixed infantry armor divisions instead? Do you think cohesive organization would have made up for the benefits of organized armored corps and the Red Army would have performed better?
