Another night, there's McCarthy *****ing, the cherry of his cigarette bobbing in the dark, *****ing that he won't be on the assault team, that he's stuck as a turret gunner for the night. We'd been out since early that morning, came back for dinner, and are preparing to raid a weapons dealer. Our first real raid. I heave my body armor onto my shoulders, settling its too-familiar weight. Then the helmet and first-aid kit and maps and radio and ammunition and rifle and all the rest. Now I look like everyone else, an arm of this strange and destructive organism, covered in armor and guns. We crowd around a satellite map spread across a Humvee hood and trace our route. Wells, my squad leader, rehearses our movements. Get in quick. Watch the danger zones. If he has a gun, kill him. I look around the group, at these faces I know so well, and feel the collective strength, this ridiculous power. The camaraderie of men in arms plays a part, for sure. The shared misery and euphoria and threat of death. But there is something more: the surrender of self, voluntary or not, to the machine. Do I believe in the war? Not important. Put that away and live in the moment, where little is knowable and even less is controllable, when my world narrows to one street, one house, one room, one door.
