"Many celebrities and self-appointed authorities have returned from quick tours of war zones (some of them getting within hearing distance of the shooting) and have put out their personal theories to batteries of photographers and reporters. Some say the American soldier is the same clean-cut young man who left his home; others say morale is sky-high at the front because everybody's face is shining for the great Cause. They are wrong. The combat man isn't the same clean-cut lad because you don't fight a kraut by Marquess of Queensberry rules. You shoot him in the back, you blow him apart with mines, you kill or maim him the quickest and most effective way you can with the least danger to yourself. He does the same to you. He tricks you and cheats you, and if you don't beat him at his own game you don't live to appreciate your own nobleness. But you don't become a killer. No normal man who has smelled and associated with death ever wants to see any more of it. In fact, the only men who are even going to want to bloody noses in a fist fight after this war will be those who want people to think they were tough combat men, when they weren't. The surest way to become a pacifist is to join the infantry."
