You're dealing with an expert

Trautman: I don't think you understand. I didn't come to rescue Rambo from you. I came here to rescue you from him.
Teasle: Well, we all appreciate your concern Colonel, I will try to be extra careful!
Trautman: I'm just amazed he allowed any of your posse to live.
Teasle: Is that right?
Trautman: Strictly speaking, he slipped up. You're lucky to be breathing.
Teasle: That's just great. Colonel, you came out here to find out why one of your machines blew a gasket!
Trautman: You don't seem to want to accept the fact 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.
