I was always a decent shot with whatever I picked up but never in his league. I know how to direct a battleship's guns but I never got to shoot those either.
The biggest thing I ever shot was a 5"/50 ship's gun. Some army guys down at Ft Hood were nice enough to let a Navy guy shoot an M1 Abrams main gun. They wouldn't let me aim it but I did get to pull the trigger. It's a lot louder outside the tank than inside.
