I do think you forget one thing, a TON of their strategies were always turned upside down by Hitler.
Allies Generals stated (after the war) that the ideas that some of his Generals had (Axis) would have given Hitler europe, but he thought he was a military genius, not just a political genius (I hate giving compliments to that bastard).
BUT in defense of Rambo's post , they were stupid enough to follow his dumbass tactics even if they knew it was a lost cause.
NOTE: Many of the combatants on both sides had WW1 experience, best xp you can have.
