If you havent already, u need to pick up Hitler's war, by heinz magenheimer. It provides the best statistics, using recently released soviet information. But it is not an 'alternate' history, or a , he should have done this, or done that. Or a monday morning quarterback(not sure if the euros will understand that expression, ill explain later). It just gives the facts, and shows the options germany had at the time, and gives you pros, cons, of the potential stratgies. This is a great book. Although read with a weary eye when he talks about the reason for war with the soviet union. Your eyes and ears(or the thing in your eye and your earache) CVM
