In 1956, the Iroquois, commonly known as the Huey, first flew as an Army replacement for the H-13 medevac helicopter of Korean War fame. By the end of the 20th century, Bell had produced more Hueys than any other American military aircraft, except for the Consolidated B-24. Superbly suited to the air mobility and medical evacuation missions in Vietnam, the Huey became an indelible symbol of that conflict.This UH-1 compiled a distinguished combat record in Vietnam from 1966 to 1970 with four units, including the 229th Assault Helicopter Battalion of the 1st Cavalry and the 118th and 128th Assault Helicopter Companies. Numerous patches on its skin attest to the ferocity of missions flown while operating as a "Smoke Ship," laying down smokescreens for air assault operations with the 11th Combat Aviation Battalion.
