Band of Brothers:
1.
Lieutenant Speirs: We're all scared. You hid in that ditch because you think there's still hope. But Blithe, the only hope you have is to accept the fact that you're already dead. And the sooner you accept that, the sooner you'll be able to function as a soldier is supposed to function. Without mercy. Without compassion. Without remorse. All war depends on it.
2.
Lieutenant: The Germans are going to cut off the roads to Bastogne. You'll be surrounded sir.
Winters: We're paratroopers, Lieutenant. We're supposed to be surrounded.
"Killin,...what do you know bout killin?"

Full Metal Jacket is full of some greats too, but I don't even want to get started.

The best line from Band of Brothers:
"How do I feel about being rescued by Patton? I'd feel real peachy about it, except for one thing. We didn't need to be f'ing rescued by Patton, you got that."
