There's an old saying, "If you kill for fun, you're a sadist. If you kill for money, you're a mercenary. If you kill for both, you're a marine."
It's good to know that this charming piece of wit isn't just hyperbole.
Lt. Gen. James Mattis, at a public forum recently said, "Actually, it's a lot of fun to fight. You know, it's a hell of a hoot . . . it's fun to shoot some people."
It's unfortunate that the crusades of old didn't have soldiers like General Mattis. For if they had, there probably wouldn't be any Arabs left to fight.
