You don't seem to want to accept the fact
that you're dealing with an expert in guerrilla warfare. With a man who's the best. With guns, with knives, with his bare hands. A man who's been trained to ignore pain, ignore weather, to live off the land, to eat things that would make a billy goat puke.
In Vietnam his job was to dispose of enemy personnel. To KILL! Period! Win by attrition. Well Rambo was the best.
