DtG -- Not quite the same thing, is it? War on a battlefield is a bit different from a car bomb in London where there is no military advantage to be gained, where the only "combatants" killed are people going about their daily lives with no idea they're combatants till they're killed or maimed.
Good point about the bomber pilots. Maybe lumping military in the definition is a mistake. At least the pilots, presumably, would not bomb the civilian populations of nations with whom there is no war. (Yeah, I know. Nixon bombed Cambodia; I was and still am appalled by that. Didn't believe the domino theory of the day, so I was opposed to the war in Vietnam. I considered it asshole politicians — read Kennedy and Johnson — sticking their noses into something the didn't understand for reasons that didn't hold water.) I was in the military at the time (USAF, 1961-1966) and I just didn't believe the lines we were being fed. Even had some trouble over it, especially since I had a sign in my room that said "Stamp out witchhunts — abolish the HUAC" and, horror of horrors, a subscription to Sing Out magazine.
