"For decades the model for understanding PTSD has been 'fear conditioning': quite literally the lasting psychological ramifications of mortal terror. But a term now gaining wider acceptance is 'moral injury.' It represents a tectonic realignment, a shift from a focusing on the violence that has been done to a person in wartime toward his feelings about what he has done to others—or what he's failed to do for them."
From the darkness of a box in the Nevada desert, he watched as three men trudged down a dirt road in Afghanistan. The box was kept cold—precisely sixty-eight degrees—and the only light inside came from the glow of monitors. The air smelled spectrally of stale sweat and cigarette smoke. On his console, the image showed the midwinter landscape of eastern Afghanistan's Kunar Province—a palette of browns and grays, fields cut to stubble, dark forests climbing the rocky foothills of the Hindu Kush. He zoomed the camera in on the suspected insurgents, each dressed in traditional shalwar kameez, long shirts and baggy pants. He knew nothing else about them: not their names, not their thoughts, not the thousand mundane and profound details of their lives.
He was told that they were carrying rifles on their shoulders, but for all he knew, they were shepherd's staffs. Still, the directive from somewhere above, a mysterious chain of command that led straight to his headset, was clear: confirmed weapons. He switched from the visible spectrum—the muted grays and browns of "day-TV"—to the sharp contrast of infrared, and the insurgents' heat signatures stood out ghostly white against the cool black earth. A safety observer loomed behind him to make sure the "weapon release" was by the book. A long verbal checklist, his targeting laser locked on the two men walking in front. A countdown—three…two…one…—then the flat delivery of the phrase "missile off the rail." Seventy-five hundred miles away, a Hellfire flared to life, detached from its mount, and reached supersonic speed in seconds.
