You ever heard of having a standing army bro? It means my country uses my taxes to pay people to be professional soldiers - a concept revolutionized by the Romans, and quite the hallmark of an advanced society.
If our soldiers have to root the Republican gaurd out of Bahgdad, that sucks. But that's what they VOLUNTEERED to do and get TRAINED and PAYED to do.
Kind of like Dru getting payed to spray on CC.com if you will.
