Hi Keebler
Sorry - have to say - I'm not completely convinced by your history lesson. There was nothing magic about the German army in 1939 - they used a combination of new tactics, single minded purpose and an economy on a war footing that was set to go broke if they didn't start the war when they did.
I think the early victories were more due to an ill prepared enemy and incompetence on the part of the British, Russians and the French. (The French collapsed with more tanks in the field than the Germans) When the German army met a throughly prepared (tactically and in terms of weapons) enemy they often came unstuck.
The classic example of this is the Battle of Britain - the fiction is that a few plucky British (and commonwealth) pilots managed to defeat a technically superior enemy through pluck and and the magic abilities of the Spitfire. In fact a tactically ill prepared (albeit with with better individual fighter tactics) airforce met a truly modern air defence system (central control, radar, air sea rescue boats etc etc) and got put through a meat grinder.
If you're interested check out these books - A Very Dangerous Enemy and The Wages of Destruction on Amazon. They're the best history books I've ever read.
Subs - Mind you I wouldn't be to surprised to find we've (the English) always been more worried about the French than the Russians !
