Wow! This could be a long list! In no particular order and trying to be brief. Gettysburg, Glory, Patton, Midway, Tora! Tora! Tora!, Run Silent Run Deep, In Harm's Way, Full Metal Jacket, Hamburger Hill, We Were Soldiers, Blackhawk Down, The Hunt for Red October, The Blue Max, The Bridge at Toko Ri, The Patriot, The Longest Day, Fat Man and Little Boy, Day One, The Hunley. I'm sure I've forgotten a bunch more.
