Ray,
it's nice to see some images of often neglected details of Huey! Way to go :) But, to keep in spirit with the unusual...
First a couple of pics of HA(L)-3 UH-1M Seawolf 314 Army serial No. 65-09476 in 1971. It was armed with two M158 seven shot rocket launchers, a M2HB .50 Cal MG in the right door and a minigun in the left door. Also note the smilies on stores mount dust covers :)
Another shot of a HA(L)-3 Huey with ''Nighthawk'' Starlight Scope/Xenon searchlight rig:
Here's an interesting Army UH-1C in service with 116th AHC in 1968. It was fitted as a ''Smoke Ship''. Note the oil bladder under the seats and a door mounted minigun for heavy fire suppression-neccessary when flying those dangerous low & slow Smokey missions.
The last two photos show a USAF UH-1N of the 20th SOS ''Green Hornets'' in 1971. I know those M93 door mounted minis were standard on USAF gunship Hueys in Vietnam, but what is perhaps more interesting is the backup/personal weapons displayed in front of the UH-1N. Note the weapon to the left-its a XM174 40mm automatic grenade launcher carried by some gunners for backup if the minigun jammed. XM174s saw limited use during Vietnam war and were most commonly used by the USAF airbase security units.
Note the armored plate in the chin bubble of this 20th SOS UH-1N:
I did come across some reference claiming that 20th SOS UH-1N gunships were often equiped with a M93 door mounted minigun subsystem in one door and a XM94 M129 40mm automatic grenade launcher subsystem in the other. Now, all photos of 20th SOS UH-1N gunships I've seen only show M93 in both doors-does anybody have any images of XM94 armed 20th SOS UH-1Ns?
