Redeployment by Phil Klay:
When I asked him why he felt the way he did, I got a long list. Since the deaths of two of his friends six weeks before, he’d been having mood swings, angry outbursts. He’d been punching walls, finding it impossible to sleep unless he quadrupled the maximum recommended dosage of sleeping pills, and when he did sleep he had nightmares about the deaths of his friends, about his own death, about violence. It was a pretty complete PTSD checklist—intense anxiety, sadness, shortness of breath, increased heart rate, and, most powerfully, an overwhelming feeling of utter helplessness.
“I know I won’t make it out of combat alive,” he said. “Every day, I have no choice. They send me to get myself killed. It’s f*cking pointless.”
