Vietnam War era US Army helicopter technical manual for three types of UH-1 Bell helicopters - YUH-1D, UH-1D and UH-1H.
"The Bell UH-1 Iroquois (nicknamed "Huey") is a utility military helicopter powered by a single turboshaft engine, with two-blade main and tail rotors. The first member of the prolific Huey family, it was developed by Bell Helicopter to meet a United States Army's 1952 requirement for a medical evacuation and utility helicopter, and first flew in 1956. The UH-1 was the first turbine-powered helicopter produced for the United States military, and more than 16,000 have been built since 1960. ... The UH-1 first saw service in combat operations during the Vietnam War, with around 7,000 helicopters deployed. ... During service in the Vietnam War, the UH-1 was used for various purposes and various terms for each task abounded. UH-1s tasked with ground attack or armed escort were outfitted with rocket launchers, grenade launchers, and machine guns." [Wiki].
A stalwart Army support aircraft, perhaps now best remembered by its appearance in Francis Ford Coppola's iconic 1979 Vietnam film starring Marlon Brando, Apocalypse Now.
