M*A*S*H, Season 1

Hawkeye:
Three hours ago, this man was in a battle. Two hours ago, we operated on him. He's got a fifty-fifty chance. We win some, we lose some. That's what it's all about. No promises. No guaranteed survival. No "saints in surgical garb." Our willingness, our experience, our technique are not enough. Guns and bombs and anti-personnel mines have more power to take life than we have to preserve it. Not a very happy ending to a movie. But then again, no war is a movie.
