We Were Soldiers is one I like. I like how it doesn't shy away from the Americans mistakes during Vietnam (Not as much as Platoon, but at least it doesn't depict them as gods like most films) There's a scene where an American radio operator calls in a napalm strike but gets the co-ordinates wrong, and drops it on some US soldiers. It leads to another scene which is still one of the most fucked up scenes I've seen. A soldier finds his friend whose been completely fucked up from the napalm. He tries to carry him away but the skin on his legs peels away like wet paper.
