GCM
Bill got in an answer before I saw the question, since I'm not in my office (where my computer lives) on Sat. I got one, as he did, for getting though an enlistment without being court-martialled. Never wore it and don't know where it is. When I came back to the U.S. on a troopship from Germany, my duffelbag got lost in the confusion and my dress uniform (with the GCM in the pocket) was in it.
