We had twin 50s on our boats in Nam. There’s not a tree in the entire I Corps that a 50 wouldn’t shoot straight through.
Ma Deuce. Accept no substitute. M2s are the shiznitz.
You served on swift boats? My older brother maned the twin 50’s .
I played with the M82 rifle when it was new. Our unit wasn’t TO&Eed for M2s, Weapons Platoon had M60s and 60mm mortars. Seen them, know the ballistics, hard to beat.
