Oh, and Rick, my education in WWII far exceeds yours, you read a topic and glam on to the first blurb written on it. There are many views and many disections of events, sometimes the actual answer is none of the above but all. Might I suggest a rather stimulating board game, if still avail. called "Kursk", Avalon Hill used to make it I think. Get good at that and move up to a "Strategy and Tactics" version, you will need an 8'X8' floor to play it properly as it goes down the the individual units.
