Some more examples: Saving Private Ryan, All Quiet on the Western Front, The Deer Hunter.

Personally, I would also include Schindler's List.

Saving Private Ryan, while it does give a particularly realistic view of storming Omaha Beach, and some other scenes, is also generally heroic -- the "good guys save their buddy from the bad guys" -- which serves to glorify war, giving it a "higher purpose".

I suggest Grave of the Fireflies, which is entirely about children slowly starving to death.
