The Bell UH-1 Iroquois - better know as the Huey - gained fame when it was used by the American forces in the Vietnam War of the sixties. It became an irreplaceable piece of modern battlefield equipment that saw rescue, troop transport and armed escort duty. When the heavy machine guns, rocket pods and nose mounted grenade launcher were introduced, the UH-1B and C received the nickname "Huey Hog". It was also flown by the Marine Corps as the UH-1E.
