“Here's what you need to know: some cliches are true, and war is definitely hell. It's being afraid all the time, and when you're not afraid it's because you're pumped full of adrenaline you could literally burst. It's watching people who you love- really profoundly love- get blown to pieces right next to you. It's seeing a leg lying in the ditch and picking it up to put it in a bag because no man- or part of a man, your friend- can be left behind. It's the dark night of the soul. There's no front line over there. The war is all around them, every day, everywhere they go. Some handle it better than others. We don't know why, but we do know this: the human mind can't safely or healthily process that kind of carnage and uncertainty and horror. It just can't. No one comes back from war the same.”
