US. Marine Prayer

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.
Without me my rifle is useless.
Without my rifle, I am useless.
I must fire my rifle true.
I must shoot straighter than my enemy who is trying to kill me.
I must shoot him before he shoots me.
I will.
