Towards the end of 1969, the US Government announced the first steps toward the reduction of US forces and eventual pullout from Vietnam. The Huey became a vital part of this plan. The South Vietnamese Air Force was responsible for taking over combat operations with a goal of fielding 500 Bell UH-1s divided amongst 16 squadrons.
While President Nixon authorized a Cambodia incursion called Operation Toan Thang 43 in 1970, US troops continued to pull out of Vietnam. All Navy Hueys were out of Vietnam by January 1972 and Marine Hueys were out of the conflict shortly thereafter. The small number of helicopters flown by the US Air Force were out of the country by the end of the year.
