In the Vietnam War, the Mobile Riverine Force (MRF) (after May 1967), initially designated Mekong Delta Mobile Afloat Force, and later the Riverines, were a joint US Army and US Navy force that comprised a substantial part of the brown-water navy. The 9th Infantry Division's area of operations was in the rivers and canals of the Mekong Delta from 1967 to 1972. Operating deep within the Viet Cong (VC)–controlled Delta, the Division was charged with protecting the area and its population against VC insurgents and ensuring the success of the South Vietnamese government's pacification program.

"Pink teams" of scout and attack helicopters, such as OH-6 "Loach" or OH-58 Kiowa scout helicopters and the AH-1 Cobra attack helicopter during the Vietnam War. Hunter killer operations are prolonged operations conducted in irregular warfare by a unique and specifically organized force, in conjunction with an indigenous force, against irregular warfare adversaries by operating behind the lines or in hostile areas.

In 1965, the concept of helicopter-borne fighting forces was still new and largely untested, and units in Vietnam invented tactics on the spot. The U.S. Army began to use Bell OH-13 Sioux and Hiller OH-23 Raven helicopters, once artillery spotters, to scout ahead of UH-1D Huey formations in the moments before air assaults to gather information about landing zones and enemy locations.

The 16th flew combat missions in Southeast Asia where it was charged with attacking convoys on the Ho Chi Minh Trail, the defense of hamlets and fire bases, providing close air support to troops in contact with the enemy, providing convoy escort, and battlefield illumination, November 1968 – July 1974. In all 53 members of the 16 SOS were killed in action during the Vietnam War.

The 54th Artillery Group provided general support for II Field Force Vietnam Artillery and served at Xuan Loc. Later moving to Ben Hoa in 1968. On 18 May 1969 at 01:00 the 7th Battalion, 9th Artillery Regiment and the 2nd Battalion, 35th Artillery Regiment, 54th Artillery Group at the base were attacked by elements of the Viet Cong (VC) 5th Division. Some VC penetrated the perimeter, but were driven back by the artillerymen. The defenders were supported by helicopter gunships, air strikes and AC-47 Spooky gunships. As the action continued a unit of the 11th Armored Cavalry Regiment arrived and engaged the VC. Fighting continued until 06:00 resulting in 24 VC killed and 14 U.S. killed.

The concept of the door gunner originated during the Vietnam War, when helicopters were first used in combat in large numbers. The original personnel who served as early door gunners aboard CH-21, UH-34, and UH-1 helicopters in Vietnam, were enlisted men, with a designated and specially trained crew chief serving as both the aircraft's maintenance manager and a door gunner. Normally, a second enlisted soldier served as a second door gunner (such as on a UH-1, and UH-34, which both used two gunners – one on each side of the aircraft). Later, as the war progressed, the door gunner position sometimes used a non-aviation rated/trained soldier or marine, that volunteered for door gunner duties.
