Just a 12 gauge slug I suppose. Three inchers got some recoil from from a seven and a half pound gun. Next down would be a .50 AE Desert Eagle.
Thanks for your service!👊🏻🇺🇸
Got to love some 40mm trained with the M79 which I loved but later was issued the M16 with the M203.👊🏻🇺🇸I was gonna say a 40mm grenade, but I see I'm already beat.
One stormy day we were flying under the scud at about 800' or so, southbound feet wet in the general vicinity of Duc Pho. Out of the mist we came upon you guys just as you were firing a mission with the 16" guns, we were maybe a mile away, a very impressive sight for us, we of course stayed outboard of the ship.
