Ironically, though our society of affluence brings safety and stability, it doesn't bring psychological health. As wealth goes up, suicide and depression rates tend to go up. I read one study that compared women in North America with women in Nigeria, and the group with the highest rates of depression was urban North American women, which is the wealthiest. Now, there are obviously huge stresses that come with poverty, but the poorer the society, the more collaborative people have to be.

In my eyes Marlantes has become the pre-eminent literary voice on war of our generation. He is a natural storyteller and a deeply profound thinker who not only illuminates war for civilians, but also offers a kind of spiritual guidance to vets themselves. As this generation of warriors comes home, they will be enormously helped by what Marlantes has written. I’m sure he will literally save lives.

The army consists of the first infantry division and eight million replacements.

I had grown up during Vietnam. I had no connections to the U.S. military, and I had a pretty cynical default opinion about the U.S. military.

The only thing that makes battle psychologically tolerable is the brotherhood among soldiers. You need each other to get by.

Combat isn't where you might die -- though that does happen -- it's where you find out whether you get to keep on living. Don't underestimate the power of that revelation. Don't underestimate the things young men will wager in order to play that game one more time.

At 19, your brain hasn't finished wiring itself. So the first time you have a good friend die, most people don't go through that at 19. Soldiers do. They're facing life in this accelerated, compressed form, and a lot of times, they're not ready for it.
