First off, hard to call the Blackhawk the Ensign Eliminator, when there are no ensigns in the army (only the navy felt the need to rename all the officer ranks). Second, the majority of the flying in the Army is done by warrant officers anyway. Minor points, I know, but it's like calling the blackhawk a huey. It just ain't right.
And I agree, the Osprey has already earned itself the nickname of "Marine Killer." It's a shame it took the big heads so long to realize that it wasn't fit for service yet.
