This has been asked other places - but I'll ask it here too! I think it's fun to discuss.
My own personal top three (no comments on the Cold War yes I like the Cold War stuff):
Heroes Of The Gap - The LNL tie into the WAW world (CAN'T WAIT!!!)
Limited Contingent of Soviet Forces in Afghanistan (Soviet 79 - 85 vs. Muhajadeen) - emphasis on VDV and Spetznaz.
Red Dawn (a bit silly I know) - U.S. Irregulars versus Cuban Paratroopers and Soviet Occupation Forces
