1. Band of Brothers - This needs no explanation
2. Enemy at the Gates - A great niche film in the war genre
3. Patton - A great epic in its own right.
4. We Were Soldiers - This one really gets to me
5. Black Hawk Down - A enligtening movie to say the least
6. Bridge Over The River Kwai - Dark but not unfairly anti-war picture of POW life under the Japanese
7. Tora! Tora! Tora! - Truly a classic, but it can be a bit draggy...
8. The Great Escape - Love that theme. Not as good as Kwai though.
9. Gettysburg - Great reenactments, acting, and of course, the history is incredible
10. Full Metal Jacket - Dark, but a classic
11. The Longest Day - good solid retelling of D-Day, but a bit optimistic about the realities of war.
12. Saving Private Ryan - One truly great scene, a bunch of 'meh'
13. Apocalypse Now - Same problem as SPR...rather, it was good, but only one scene was 'war movie' -- only on the list because of Killgore's attack on the beach.
14. Master and Commander - not really a 'true' war movie, but I'll lump it in.
I stole a bunch from PurdueRY's list, but it got out of hand. 😛
