Holy shit! Those are a lot of suggestions...
To add some more, here is a best/worst war movie list from the NY Daily News (by critic Joe Neumaier)
http://www.nydailynews.com/entertainment/movies/galleries/the_top_15_best__worst_war_movies/the_top_15_best__worst_war_movies.htmlBest:
"Apocalypse Now" (1979)
The phantasmagoria and trippiness of war, told with mystery and mist-enshrouded madness. Forget about Brando's size — it's the size of the movie here that counts.
"Saving Private Ryan" (1998)
Steven Spielberg's drama of identity and comradeship gets better and feels more classic with age. Trim away its unnecessary book-ending sequence, and it's as taut and tense as any war film ever made.
"Pork Chop Hill" (1959)
The Korean War, so often second tier in Hollywood, gets the focus here in a drama about one of the major battles of that short conflict. Gregory Peck is the lieutenant whose leadership is ideal. It's directed by Lewis Milestone, almost three decades after he tackled the Great War in 'All Quiet on the Western Front.'
"Paths of Glory" (1957)
Stanley Kubrick's drama about soldiers in World War I put on trial for refusing to take part in a suicide attack. An early scene of commanding officer Kirk Douglas walking through the trenches is like a short tour through Hell.
"Full Metal Jacket" (1987)
Kubrick's other film on this list is notable for its split approach; The training of soldiers, and some of their experiences in Vietnam. One of the many reasons it works so well is because, having seen them be conditioned to violence, we instinctively flinch as the camera catches them, helpless, in the midst of so much of it.
"Letters From Iwo Jima" (2006)
Clint Eastwood's far more accomplished companion film to the same year's 'Flags of Our Fathers' examines the Japanese war from the side of the enemy. Thoughtful, decent and beautifully acted, it doesn't matter whether this film is about the Allies or the Axis - it's about men in battle.
"The Hurt Locker" (2009)
Trip-wires, booby-traps, unfriendlies, exhaustion — Kathryn Bigelow's dissection of modern warfare is set in Iraq, but it's also about what war has become: Both external and internal, with explosions and tension that take victims in portions.
"Platoon" (1986)
Operatic and mythic, Oliver Stone's Oscar-winner seems split between youth and experience because that's how his protagonist — a version of himself — saw Vietnam. The schizophrenia in the movie is never explicit, but everything here has two sides.
"Sergeant York" (1941)
Famously noble and iconically heroic, Gary Cooper's title soldier has become World War I shorthand for the metamorphosis of war — here, its American outskirts to pacifist to sharpshooter to war hero.
"All Quiet on the Western Front" (1940)
Erich Maria Remarque's plaintive cry for Germany's lost youth in the First World War is grippingly filmed by director Lewis Milestone, in the first military epics of the sound era.
Worst:
"Pearl Harbour" (2001)
Michael Bay's attempt at serious, epic, 'Doctor Zhivago'-style love and war drama. Emphasis on the word 'attempt.'
"Midway" (1976)
Stodgy and gray, this Charlton Heston-Henry Fonda-Robert Mitchum drama about the turning of the tide in the Pacific is old-fashioned to a fault.
"Hamburger Hill" (1987)
One of the '80s war-film footnotes, John Irvin's Vietnam flick is notable mainly for a performance by the young Don Cheadle.
"A Bridge Too Far" (1977)
The '70s did disaster films really well. Yet even under those wide parameters, Richard Attenborough's massive undertaking is bloated.
"Heartbreak Ridge" (1986)
Clint Eastwood's mid-career military effort lacks punch and drive, and Eastwood's persona, oddly, is too distracting for a military movie. Its scenes of Marine Clint's domestic life clicks, though.
"Battle of the Bulge" (1965)
Another Fonda vehicle, here as a Lieutenant colonel hoping to have his men ready to invade Germany in 1944 — then Hitler takes Antwerp. History Channel documentaries have more punch than this dry exercise.
"Inchon" (1981)
Let's not talk about the absurd romantic subplot involving Jacqueline Bisset and Ben Gazzara. Let's just say Laurence Olivier as General MacArthur going to Korea is 'SNL'-quality parody. Only its serious.
"To Hell and Back" (1955)
Audie Murphy plays himself in this drama about Audie Murphy, the most decorated soldier of World War II. Note that's not 'actor,' that's 'soldier.' Based on the autobiography by — you guessed it — Audie Murphy.
"The Green Berets" (1968)
Okay, it has a great theme song. but the rest of this knee-jerk John Wayne vehicle is reactionary against what was happening in America instead of what was happening overseas.
"The Longest Day" (1962)
The story of D-Day, though the title says it all.
