as a gunner in the Navy I got to shoot the M-1,M-14,BAR, 30 air,
M-60 at the 500 yard targets.
Never got a chance to shoot the 50 cal sniper or the 106 recoiless
......just got to clen them......bummer.
However shoting the rear 5" on the back of the DE "White Russian" on manual control ,off the Catalina islands, made up for it.
Yep, iron sights , at six miles!!
