Anything by David Glantz. If you have the money, his books on Deep Battle and Soviet operational art/armored manoeuver are worth it.
Goering was an idiot, I never heard anything bad about him other than the blunder at the at the outskirts of Stalingrad. The Red Air Force shot down most of the airdrops. and the ones that fell mostly got into the hands of Red Army soldiers. I've heard of some of them using MG42's. Fill me in on details.P.S. Update, Try reading Russia's War by Alexander Werth. It's pretty long, but very informative. I have a very old copy, many of the maps in my book are missing:( Hope it doesn't happen to you if you get a copy.
