Nope, but I can guarantee he sure won't lunge forwards. I was on a tanker in the Gulf of Tonkin on that morning. I previously served in The Nation Guard and US Army, where I earned Expert Marksmanship with both the M1 and Carbine. I fired BAR's Thompsons, and grease guns, even Quad fifties when in the National Guard along with being a crew chief on an m19 gun carriage which sported twin 40's. So I have fired of a few rounds.
Twin 40’ gun captain here. (Heavy Cruiser - ‘46 — ‘47)
