-Frank Sheeran spent 411 combat days as an Army Rifleman in WWII. Fucking guy probably killed more people than the plague.
-Stevie Flemmi was a paratrooper in Korea. I think he was highly decorated too.
-Allen Dorfman was a Marine in WWII. He was at Iwo Jima and got a Silver Star
More recently Richard Greaves(Colombos) and Randy Pizzolo(Bonnanos) were both Marines.
