In Vietnam, he tried to pull off the deception that he had fellow soldiers, that he was one soldier among others, but his association with the Company, with CIA, was obvious. No one in the battalion impugned his courage, no one doubted he would fire his sidearm. But there was a vague sense that he was here electively: not a draftee, but not a volunteer either, something else. The men wouldn’t have said it this way, but they suspected he had other exits, and a place waiting for him in a boardroom somewhere with wainscoting and claret. Now, in Iraq, he tries to live in accordance with what he thinks is the truth: that he is not their fellow soldier, not one soldier among others, but a vile opportunist or craven functionary of some sort, of a sort much worse than they, and that his compromises set him apart. But these new men will not have it; cynics and hedonists and brothers, they embrace him as one of their own.
But Doc wouldn’t want to hear it. He’s not unimaginative, he’s got a greater ambit than short-sheeting or selling a “scorpion” in an empty matchbox, but he’s already let Milo know he has a short fuse for existential quailing and high mopery.
