Be careful with this "what if" talk on other forums, I did it on a UK site and almost got banned for "wanting" the nazi's to win the war???!!!.....My theoryis the kv1 really shook up the german army. The soviets could park a KV1 in an important crossroads in 41 and those crossroads were more or less closed till they could get an airstrike or they could bring up an 88.IMO this left a lasting impression on the german army and as a result they produced a whole list of overweight underpowered really hard to produce tanks.I really like to understand history, one of the tools I use to try to understand history is to run a whole bunce of "what if's" through my head.....
