From Full Metal Jacket
Gunnery Sergeant Hartman
[Hartman gives a speech to the graduating recruits
] Today, you people are no longer maggots. Today, you are Marines. You're part of a brotherhood. From now on until the day you die, wherever you are, every Marine is your brother. Most of you will go to Vietnam. Some of you will not come back. But always remember this: Marines die. That's what we're here for. But the Marine Corps lives forever. And that means YOU live forever.
