While serving on a joint staff in Europe, the AF pilots were constantly tremarking about the cool, non-PC squadron names and patches of the Navy and Marine units. Also liked the way we could wear (almost) any patches on our flight jackets. Its tough to beat names like the Jolly Rogers, Grim Reapers, and the classic, the Pukin' Dogs.
In our squadron the C.O. would sometimes hint to some of us JO's to "commemorate" an event or an action with a creative patch. Didn't mean much to outsiders, but was great for morale.
