I'll jump in and list a few from "Full Metal Jacket"

"The dead know only one thing: it is better to be alive."

Private Joker: Are those... live rounds?
Private Gomer Pyle: Seven-six-two millimeter. Full. Metal. Jacket.

Gunnery Sergeant Hartman: The deadliest weapon in the world is a marine and his rifle. It is your killer instinct which must be harnessed if you expect to survive in combat. Your rifle is only a tool. It is a hard heart that kills.

Pogue Colonel: You write "Born to Kill" on your helmet and you wear a peace button. What's that supposed to be, some kind of sick joke?

Gunnery Sergeant Hartman: What's this weapon's name, Private Pyle?
Private Gomer Pyle: Sir, the private's weapon's name is Charlene, sir!
Gunnery Sergeant Hartman: Private Pyle, you are definitely born again hard. Hell, I may even allow you to serve as a rifleman in my beloved Corps.
Private Gomer Pyle: Sir, yes, sir!

Gunnery Sergeant Hartman: [chanting] This is my rifle.
Gunnery Sergeant Hartman: [grabbing their ?????????] This is my gun.

Gunnery Sergeant Hartman: I don't want no teenage queen
Gunnery Sergeant Hartman: I just want my M-14

Sgt. Hartman: Did your parents have any children that lived?!
"Gomer Pyle": Sir, yes, sir!
Sgt. Hartman: I'll bet they regret that.

Many other great ones. Most of which can't be printed here.
