Talk about something that can make a man feel inadequate! Jeez.
We had something like that, though ours was mobile.
Three beltfed machineguns, a 90mm cannon, a couple of .45 greaseguns and a salvaged Thompson, an M79 and AK, sometimes an M14 and shotgun as well, plus a .50 M2 for the boss, and a lot of the time, there were three of us instead of four. M1911A1 .45 pistols for all, plus my Browning GP and my driver's .38 sixgun, plus ammo, 10,000 rounds just for the .30 caliber MG, and around 50 for that 90mm- High Explosive, HEAT, Canister and WP, among other possibilities. Called an M48A3, it was.
Well, sometimes we were mobile....
