OK - I may be giving a repeat or not:
Battleground Battleground (1949) - IMDb
Tuskegee Airmen The Tuskegee Airmen (TV Movie 1995) - IMDb
Midway Midway (1976) - IMDb
And while its more a light-hearted look at the Cold War
The Russians Are Coming, the Russians Are Coming The Russians Are Coming the Russians Are Coming (1966) - IMDb
And I know its a stretch but
The Invisible Agent (with Peter Lorre as a Japanese intelligence officer)
The Bunker - a really thrilling horror movie (2001) The Bunker (2001) - IMDb
If Starship Troopers makes the cut, I think Aliens should be on the list too.
Some of these are borderline, but it looks like we’re using a wide border

Has All Quiet on the Western Front (1931) been mentioned yet? 
A military courtroom drama: Town without Pity with Kirk Douglas and a scrumptious Christine Kaufmann. :o
Another tangentially military courtroom drama: Anatomy of a Murder, one of the best movies ever made. Jimmy Stewart, George C Scott, Ben Gazarra (whose character was an Army lieutenant), Lee Remick, Arthur O’Connell. Directed by Otto Preminger. They just don’t make 'em like that any more!
Another Preminger war flick: *** In Harm’s Way***. John Wayne, Kirk Douglas, Patricia O’Neal.
Have ***Sink the Bismarck ***and ***The Dam Busters ***been mentioned yet? 
Cockleshell Heroes
Went The Day Well? - Doughty British villagers take on a German advance invasion force…
The Password Is Courage - Would be ludicrous if the exploits of the inappositely named Charles Coward weren’t true…
A Matter of Life and Death AKA ‘Stairway To Heaven’ - Not a war film as such, but set in the war. I always seem to get something in my eye when I watch it…
The Hill
I remember a film I watched quite a few years back about German POWs in a Scottish prison camp, some eventually escaping on a U Boat. Great film, but the title escapes me. Does anyone know it?
The MacKenzie Break, starring Brian Keith of ***Parent Trap ***and Family Affair fame.
Crossbow and Overcast, about the Allied campaign against Germany’s V-weapons.
The McKenzie Break - The title popped into my head as soon as I pressed ‘submit’…
Edit: Thanks Terentii… too quick for me!
A somewhat obscure movie, but one well worth watching: Battle of the Bulge with Henry Fonda and Robert Shaw. This scene alone makes it worthwhile:
The dude in the grey uniform with the overseas cap was a German in just about every war movie made in the '60s, including The Great Escape and Kelly’s Heroes.
This movie was my introduction to classical music:
To this day, I can’t listen to Tannhauser without thinking about it!
King of Hearts with Alan Bates
Cross of Iron with James Coburn and Maximilian Schell
Fail Safe with Henry Fonda, Walter Matthau, and Larry Hagman
I love this movie, but unfortunately my suspension of disbelief is rocked every time I see the 50-star US flag hanging in Larry Hagman’s office. (Yes, you CAN tell the difference, even when the flag is folded!)
Of all the stellar performances in this movie, my favorite will always be Donald Pleasance as Heinrich Himmler. I knew he was just an actor playing a role, but he still scared the crap out of me! :eek:
