After the sixth suicide in his old battalion, Manny Bojorquez sank onto his bed. With a half-empty bottle of Jim Beam beside him and a pistol in his hand, he began to cry.
He had gone to Afghanistan at 19 as a machine-gunner in the Marine Corps. In the 18 months since leaving the military, he had grown long hair and a bushy mustache. It was 2012. He was working part time in a store selling baseball caps and going to community college while living with his parents in the suburbs of Phoenix. He rarely mentioned the war to friends and family, and he never mentioned his nightmares.
He thought he was getting used to suicides in his old infantry unit, but the latest one had hit him like a brick: Joshua Markel, a mentor from his fire team, who had seemed unshakable. In Afghanistan, Corporal Markel volunteered for extra patrols and joked during firefights. Back home Mr. Markel appeared solid: a job with a sheriff’s office, a new truck, a wife and time to hunt deer with his father. But that week, while watching football on TV with friends, he had wordlessly gone into his room, picked up a pistol and killed himself. He was 25.
