I pose the question that had it not been for the disastrous Soviet attack on Finland, they may well have lost the Eastern Front. I say this after reading a chapter on the Soviet Army. I would suggest that: 1. It showed how impractical their early armour was. 2. It made the soviets really consider winter clothing (a surprise to me) 3. It showed up serious flaws in their command after the Stalin purges (I read that they needed to scape the prisons to find competent officers). 4. It taught them valuable lessons in logistics. After reading the chapter, I felt that a Soviet army would not have held Moscow if not for the lessons learnt from the Finnish war.
