<< Guess I'm a fan of the classics:
Tora! Tora! Tora!
Kelly's Heroes
Full Metal Jacket
Cross of Iron (not well-known but incredible East Front battle scenes for its time...had real T-34 tanks!)
Dr. Strangelove (Hmmm...can it count as a WAR movie though?)
The Big Red One
Das Boot
Patton
Oh...and I'll add some TV shows I LOVED as a kid:
Combat! (caught it in re-runs)
Rat Patrol (the A-Team of its day )
Hogan's Heroes >>
It's about time someone said Das Boot!
