When I was on the USS Dwight D. Eisenhower, one of the fellows who ate with us was the NIS agent assigned to the ship. He had been a policeman before working for NIS, and freely admitted that before that he had spent four years in the Air Force. To forestall any harassment, he made it quite clear that his time in the Air Force had been no picnic. In fact, he informed us, the whole time he was in boot camp, he was assigned a roommate that he couldn't get along with, and there was nothing he could do about it.
