<P> The Iroquois was originally designated HU - 1 , hence the Huey nickname , which has remained in common use , despite the official redesignation to UH - 1 in 1962 . The UH - 1 first saw service in combat operations during the Vietnam War , with around 7,000 helicopters deployed . The Bell 204 and 205 are Iroquois versions developed for the civil market . </P>
