My World of Tanks addiction succeeded in pushing me to getting started with my Eastern Front project. I binged on the first season of Greatest Tank Battles , picked up a few Perrin 10mm tanks to practice on as well as a pair of books about the battle for Kursk: FIFTH GUARDS TANK ARMY AT KURSK: 12 July 1943 (Visual Battle Guide) and Das Reich Division at Kursk: 12 July 1943 (Visual Battle Guide)
They are both a bit like super-sized Ospreys. Although they focus on Kursk, there's some introductory material about the lead up to the battle, and tons of info on the actual regiments, their equipment and tactics involved in the battle. I've only flipped through and read a few bits, but it's looks to be the type of nitty gritty wargamey minutia that most folks wouldn't care about ("how many reconnaissance motorcycles did the flakpanzer battalion have at Kursk?") but I really dig.
After asking on TMP I also got a number of other recommendations for books and films to check out to get a handle on everything from the Winter War to the fall of Berlin.
