"The sooner you acccept the fact that you're already dead, the
more you'll be able to function as a soldier is supposed to
function. No mercy, no compassion, no remorse.." think that is not
very true, as once you accept the fact that you are already dead,
you get gung-ho and careless.
Think it is more of accepting the fact that you are a soldier, and
just doing the best to stay alive to kick ass, is more important.
Than you be on the ball and sharp . Good soldiers don't enjoy
combat, they are never eager for combat, they know when to fight
when to run. People who get eager for combat, generally in their
eagerness get careless and not logical and die.
