AH1WSnake,
The Marine UH-1Es used ordnance systems and loadouts that were completely unique to the USMC. The UH-1E system was called TK-2 (temporary kit 2). TK-1 was put on the UH-34s. TK-2 was also called change 7 (because it was AFC 7). The system was basically two M-60 machine guns on each side mounted above the tally racks. It was a completely different setup than the twin 60 system the Army used (the model depicted in the 1/48 Monogram USMC version is wrong).
The Basic setup was the twin 60s and a pod on each side. The pods varied between 7 and 19 shot. In place of pods there were cases of firebombs being carried and the Helicopter Trap Weapon (HTW) - a 5inch zuni warhead on a parachute designed to clear booby traps from LZs. Some squadrons added door mounted M-60s and a nose-mounted twin 60 TAT-Emerson 101 turret.
Other systems used, though not necessarily weapons loads, included a big box of serachlights that filled up almost the entire cabin for "FireFly" missions and a system called a "Sniffer" that detected ammonia from urine and to locate camps (or waterbuffalo) under the jungle canopy.
