"Gunnery Sergeant Hartman: Today, you people are no longer maggots. Today, you are Marines. You're part of a brotherhood. From now, until the day you die, wherever you go, every Marine is your brother. And always remember this: Marines die, that's what we're here for. But the Marine Corps lives forever, and that means you live forever."
