It occurs that combat offers a new maturity. War is never a good thing but sometmes it is a necessary thing, especially when He Has Seen the Elephant.
Old soldiers in the Civil War coined a phrase for green troops who survived their first taste of battle: "He has seen the elephant."
This Army lieutenant sums up the combat experience better than many a grizzled veteran: "Well, I'm here in Iraq, and I've seen it, and done it. I've seen everything you've ever seen in a war movie. I've seen cowardice; I've seen heroism; I've seen fear; and I've seen relief. I've seen blood and brains all over the back of a vehicle, and I've seen men bleed to death surrounded by their comrades. I've seen people throw up when it's all over, and I've seen the same shell-shocked look in 35-year-old experienced sergeants as in 19-year-old privates.
