Marine Corps Rifleman's Creed

This is my rifle.
There are many like it,
but this one is mine.
My rifle is my best friend.
It is my life.
I must master it
as I must master my life.
My rifle without me is useless.
Without my rifle, I am useless.
I must fire my rifle true.
I must shoot straighter
than any enemy
who is trying to kill me.
I must shoot him,
before he shoots me.
I WILL...
