Air assault is the movement of ground-based military forces by vertical take-off and landing (VTOL) aircraft, such as helicopters, to seize and hold key terrain that has not been fully secured, and to directly engage enemy forces behind enemy lines.[1][2] In addition to regular infantry training, air-assault units usually receive training in rappelling, fast-roping techniques, and air transportation. Their equipment is sometimes designed or field-modified to allow better transportation and/or carrying within aircraft.
The United States Army field manual FM 1-02 (FM 101-5-1) describes an "air assault operation" as an operation in which assault forces (combat, combat support, and combat service support), using the firepower, mobility, and total integration of helicopter assets, maneuver on the battlefield under the control of the ground or air maneuver commander to engage and destroy enemy forces or to seize and hold key terrain usually behind enemy lines.[3]
Due to the transport load restrictions of helicopters, air assault forces are usually light infantry, though some armored fighting vehicles, like the Russian BMD-1 are designed to fit most heavy lift helicopters, which enable assaulting forces to combine air mobility with a certain degree of ground mechanization. Invariably the assaulting troops are highly dependent on aerial fire support provided by the attack helicopters, armed helicopters, and/or fixed-wing aircraft escorting them. A concept called mounted vertical maneuver requires the ability to transport light, motorized, or medium-weight mechanized force by VTOL or super STOL aircraft.[4]
Air assault and air mobility are related concepts. However, air assault is distinctly a combat insertion rather than transportation to an area in the vicinity of combat.
Air assault units can vary in organization; using helicopters not only in transport but also as close air fire support, medical evacuation helicopters and resupply missions. Airmobile artillery is often assigned to air assault deployments. Units vary in size, but are typically company to brigade sized units.
Airmobile units are designed and trained for air insertion and vertical envelopment ("a maneuver in which troops, either air-dropped or air-landed, attack the rear and flanks of a force, in effect cutting off or encircling the force",[5] air resupply, and if necessary air extraction.
One specific type of air assault unit is the US Army air cavalry. It differs from regular air assault units only in fulfilling a traditional cavalry reconnaissance and short raids role. Britain's 16 Air Assault Brigade was formed in 1999 following an amalgamation of elements of 5th Infantry Brigade (5 Airborne Brigade) and 24 Airmobile Brigade, bringing together the agility and reach of airborne forces with the potency of the attack helicopter.[6] Similarly, the US 101st Airborne Division was originally classed as airborne, then airmobile and now air assault.
History
Air mobility has been a key concept in offensive operations since the 1930s. Initial approaches to air mobility focused on parachutists and the use of military gliders. During World War II many assaults were done by military gliders. The World War Two era German Fallschirmjäger, Brandenburgers, and the 22nd Air Landing Division glider borne paras laid the foundation for modern day air assault operations.[7][8] In 1941 the U.S. Army quickly adopted this concept of offensive operations initially utilizing wooden gliders before the development of helicopters.[7] Following the war, faster aircraft led to the abandonment of the flimsy wooden gliders with the then new helicopters taking their place. Four YR-4B helicopters saw limited service in the China Burma India theatre with the 1st Air Commando Group[9]
In 1943 the Germans conducted the Gran Sasso raid which implemented many aspects of the air assault concept. Another example was the German Brandenburgers' glider borne operation at Ypenburg during World War Two.[10]
In 1946, U.S. Marine General Roy S. Geiger observed the atomic bomb tests at Bikini Atoll and instantly recognized that atomic bombs could render amphibious landings difficult because of the dense concentrations of troops, ships and material at beachheads. During this time, The Commandant of the Marine Corps, Alexander Vandegrift, convened a special board known as the Hogaboom Board. This board recommended that the USMC develop transport helicopters in order to allow a diffused attack on enemy shores. It also recommended that the USMC form an experimental helicopter squadron. HMX-1 was commissioned in 1947 with SikorskyHO3S-1s.[11] In 1948 the Marine Corps Schools came out with Amphibious Operations—Employment of Helicopters (Tentative), or Phib-31, which was the first US manual for helicopter airmobile operations.[12] The Marines used the term vertical envelopment instead of air mobility or air assault. HMX-1 performed its first vertical envelopment from the deck of an aircraft carrier in an exercise in 1949.
American forces later used helicopters for support and transport to great effect during the Korean War showing that the helicopter could be a versatile and powerful military tool.[13]
First helicopter air assaults
The first helicopter airlift and helicopter sling load mission was conducted on September 13, 1951, during the Korean War.[14] "Operation Windmill I" was conducted by the United States Marine Corps in support of a battalion clearing the enemy from a series of ridges around a basin called "The Punchbowl." In total seven HRS-1 Marine helicopters made 28 flights that delivered 8,550kg (18,848 pounds) of supplies and evacuated 74 seriously wounded men.
The plan was to use the helicopters to drop No. 45 Commando at Raswa, to the south of Port Said, in order to secure two vital bridges. Last-minute concerns about their vulnerability to ground fire meant that they were replaced in this role by French paratroops who conducted a daring low-level drop on 5 November, securing one of the two bridges intact. Instead No. 45 Commando was landed the following day, disembarking close to the seafront in the aftermath of the seaborne landing that had secured the area. This first-ever operational use of helicopters to land troops during an amphibious assault proved successful. With their carriers lying nine miles offshore, the marines were landed far more quickly than could have been achieved using landing craft, and without the need to get their boots wet. However ... they landed the marines in much the same place that old style landing craft would have put them.[16]
In 1956, the United States Marine Corps executed the first Division-strength exercise of vertical envelopment when the 1st Marine Division was helicopter-lifted from converted WWII jeep carriers to landing sites at Camp Pendleton, CA, U.S. Marine Corps Base. One of the ships utilized for this exercise was the USS Thetis Bay. This exercise was the culmination of the Marines' developing strategy of vertical envelopment rather than amphibious assaults on heavily defended beaches. The maneuvers were well-covered by the media of the time, including LIFE Magazine. The Marine Corps subsequently adopted this method as standard operating procedure after proving that helicopters could be used to transport very large numbers of troops and large amounts of supplies in a timely fashion.[citation needed]
Operation Deep Water was a 1957 NATO naval exercise held in the Mediterranean Sea that involved the first units of the United States Marine Corps to participate in a helicopter-borne vertical envelopment operation during an overseas deployment.
The use of armed helicopters coupled with helicopter transport during the Algerian War for the French Army to drop troops into enemy territory gave birth to the tactics of airmobile warfare that continues today.[18]
The machines of the French Army Light Aviation carried out a considerable number of missions against Algerian insurgents between 1955, when the Groupe d’Hélicoptères No.2 (GH 2) was created, and 1962 when the French empire in Algeria finally came to an end. GH 2 was based at Sétif – Aïn Arnat in the east of the country, and it was equipped primarily with machines to undertake transport missions, though the Vertol H-21C, would soon join the unit owing to concerns about the lack of machines which could both defend themselves and carry out offensive missions against the insurgents. Acquiring these machines lay in the hands of the licensee Piasecki given France's urgent need to have them on account of the circumstances. Usually, the H-21 could carry up to 18 troops, yet local operating (as well as climatic) conditions decreed that the French army examples could carry only up to around 12 troops each. In two years, GH 2 received the vast majority of the H-21s acquired by ALAT, which consisted of five squadrons by the end of 1958. A sixth squadron from the French naval air arm, the Aéronautique navale, had operated with GH 2 for little more than a year.
From 1955 to 1962, GH 2 took part in the major battles, which occurred near the frontier between Algeria and Tunisia, including the battle of Souk-Ahras in April 1958. The helicopters, including types such as the H-21, the Alouette II, the Sikorsky H-19 and Sikorsky H-34, together aggregated over 190,000 flying hours in Algeria (over 87,000 for the H-21 alone) and helped to evacuate over 20,000 French combatants from the combat area, including nearly 2,200 at night. By the time the war in Algeria had ended, eight officers and 23 non-commissioned officers from ALAT had died in the course of their duties.

U.S. ArmyCH-21 helicopter transports arrived in South Vietnam on 11 December 1961. Air assault operations using Army of the Republic of Vietnam (ARVN) troops began 12 days later in Operation Chopper. These were very successful at first but the Viet Cong (VC) began developing counter helicopter techniques, and at the Battle of Ap Bac in January 1963, 13 of 15 helicopters were hit and four shot down. The Army began adding machine guns and rockets to their smaller helicopters and developed the first purpose built gunship with the M-6E3 armament system.
U.S. Marine helicopter squadrons began four-month rotations through Vietnam as part of Operation SHUFLY on 15 April 1962. Six days later, they performed the first helicopter assault using U.S. Marine helicopters and ARVN troops. After April 1963, as losses began to mount, U.S. Army UH-1 Huey gunships escorted the Marine transports. The VC again used effective counter landing techniques and in Operation Sure Wind 202 on 27 April 1964, 17 of 21 helicopters were hit and three shot down.
The 2nd Battalion 3rd Marines made a night helicopter assault in the Elephant Valley south of Da Nang on 13 August 1965 shortly after Marine ground troops arrived in country. HMM-361 commanded by LtCol Tom Ross. On 17 August 1965 in Operation Starlite the 2nd Battalion 4th Marines landed in three helicopter landing zones (LZs) west of the 1st VC Regiment in the Van Tuong village complex, 12 miles (19km) south of Chu Lai, while the 3rd Battalion 3rd Marines used seaborne landing craft on the beaches to the east. The transport helicopters were 24 UH-34s from HMM-361, HMM-261 and HMM-161 in relief, escorted by Marine and Army Hueys from VMO-2 and VMO-6 led by Maj Donald G. Radcliff, US Army who was killed in action. VC losses were 614 killed, Marine losses were 45 KIA and 203 WIA.
The need for a new type of unit became apparent to the Tactical Mobility Requirements Board (normally referred to as the Howze Board) of the U.S. Army in 1962. The Board met at a difficult time; the bulk of the military hierarchy were focused primarily on the Soviet threat to Western Europe, and perceived as requiring heavy, conventional units. The creation of new, light airmobile units could only occur at the expense of heavier units. At the same time, the incoming Kennedy administration was placing a much greater emphasis on the need to fight 'small wars', or counter-insurgencies, and was strongly supportive of officers such as General Howze who were embracing new technologies.[19] The Board concluded that a new form of unit would be required, and commissioned tests – but justified these at the time on the need to fight a conventional war in Europe.[20]
Initially a new experimental unit was formed at Fort Benning, Georgia, the 11th Air Assault Division on 11 February 1963, combining light infantry with integral helicopter transport and air support. Opinions vary as to the level of support for the concept within the Army; some have argued that the initial tests against the context of conventional warfare did not prove promising, and, despite opposition from the Joint Chiefs of Staff, it was primarily the Secretary of Defense Robert McNamara who pushed through the changes in 1965, drawing on support from within the Pentagon which had now begun to establish a counter-insurgency doctrine that would require just such a unit.[21] Others have put more weight on the support of newly appointed senior Army commanders, including the new Chief of Staff General Wheeler, in driving through the changes.[22] Nonetheless, the 11th Air Assault Division assets were merged with the co-located 2nd Infantry Division and reflagged as the 1st Cavalry Division (Airmobile), continuing the tradition of the 1st Cavalry Division. Within several months it was sent to Vietnam and the concept of air mobility became bound up with the challenges of that campaign, especially its varied terrain – the jungles, mountains, and rivers which complicated ground movement.
The first unit of the new division to see major combat was the 1st Battalion, 7th Cavalry Regiment, 1st Cavalry Division, led by Lieutenant ColonelHarold G. Moore. The 7th Cavalry was the same regiment that Custer had commanded at the ill-fated Battle of the Little Bighorn. On November 14, 1965, Moore led his troops in the first large unit engagement of the Vietnam War, which took place near the Chu Pong massif near the Vietnam-Cambodia border. It is known today as the Battle of Ia Drang Valley, and is considered to be the first large scale helicopter air assault.[17]

This battalion (vice "squadron," which would have been its nomenclature had it actually been a cavalry organization) gave common currency, albeit incorrectly, to the U.S. term "Air Cavalry." However, 1-7 Cav was in actuality an infantry formation carrying a "Cavalry" designation purely for purposes of lineage and heraldry. (True air cavalry organizations are/were helicopter-mounted reconnaissance units.) Light infantry-centric organizations (battalions, brigades, or divisions) that are trained, organized, and equipped to operate with organic (i.e., owned by the joint parent headquarters of both the light infantry organization and the supporting aviation organization) are classified as "Air Assault," previously designated as "Airmobile."
The Vietnam-era 1st Cavalry Division (Airmobile) was not an "air cavalry" division, per se, although it did contain air cavalry squadrons. The division was a new concept that probably was more akin to a modern version of "mounted rifles," owing to its helicopter "mounts," and, as did 1-7 Cav discussed above, carried the "Cavalry" designation primarily for purposes of lineage and heraldry, and not because of its then current mission or organizational structure.
On a practical level, virtually any light infantry formation can instantly become "airmobile" simply by dividing the assault elements into "chalks" (aircraft load designations pertaining to order of loading and type of aircraft), embarking them on the aircraft, transporting them to the objective/assembly area, and inserting/disembarking them into a landing zone, etc. However, true "air assault" organizations are specialized light infantry (much like airborne troops), who are trained, organized, and equipped specifically to perform the complex, rapid, and dynamic tasks inherent in air assault vice simply being transported by aircraft. Perhaps a rough comparison can be made between "motorized" and "mechanized" infantry. Any light infantry unit can be transported by truck (viz., "motorized"), however, "mechanized" infantry are specifically trained, organized, and equipped to conduct operations in close-coordination with tanks.
Southern African wars

The airmobile warfare tactics used by Portugal, Rhodesia and South Africa had many similar characteristics. The air forces of the three countries also used the same types of helicopters (mainly Alouette III and later, regarding Portugal and South Africa, SA 330 Puma), and there were military cooperation agreements and sharing of experience between the three powers, including the secret Alcora Exercise.
Portuguese, Rhodesian and South African airmobile tactics often involved air assaults done by small units of special forces or light infantry, transported in four or five Alouette III helicopters. Assaults were often supported by an Alouette III armed with a side-mounted 20mm MG 151autocannon. This helicopter was nicknamed Helicanhão (heli-cannon) by the Portuguese and K-Car by the Rhodesians. Variants of the air mobile warfare tactics used in Africa included the Rhodesian Fireforce and the Portuguese heliborne-horseborne forces cooperation.[23][24][25]

In the United States Army, the air assault mission is the primary role of the 101st Airborne Division (Air Assault).[26] This unit is a division-sized helicopter-borne fighting force.[26] 101st Airborne Division soldiers attend the Sabalauski Air Assault School.[2] Graduates are qualified to insert and extract using fast rope and rappel means from a hover in addition to the ordinary walk on and off from an airlanded helicopter.
In addition, all U.S. Marine Corps divisions are capable of, and routinely train for and perform, air assault operations. Forward-deployed Marine Corps infantry battalions/regiments (reinforced, organized, and designated as Battalion Landing Teams/Regimental Combat Teams, or BLTs and RCTs, respectively), form the Ground Combat Element (GCE) of a Marine Expeditionary Unit (MEU), or Marine Expeditionary Brigade (MEB). These MEUs and MEBs are capable of embarking aboard amphibious warships and include air assault as one of several means of conducting amphibious landing operations, supported by embarked Marine Corps tilt-rotor, helicopter, and STOVL fixed-wing strike aircraft.[27][28][29]
The 10th Mountain Division Light Infantry has a limited capability to perform air assault operations. On September 19, 1994, the 1st Brigade of the 10th Mountain Division conducted the Army's first air assault from an aircraft carrier, the USSDwight D. Eisenhower, as part of Operation Uphold Democracy.[30] This force consisted of 54 helicopters and almost 2,000 soldiers. This was the Army's largest operation from an aircraft carrier since the Doolittle Raid of World War II
The Battle of Antonov Airport was an operation during the opening days of the 2022 Russian invasion of Ukraine where the Russian Airborne Forces (VDV) attempted an air assault in order to capture Hostomel Airport, in order to use the airport to airlift troops and heavy equipment directly into Kyiv. The VDV was initially able to capture the airport, but without artillery or armored support they were not able to handle a counter-attack started by local Ukrainian forces.[31] The airport was captured only on the second day by a second air assault combined with an armored push from ground troops.[32]
A simultaneous air assault was attempted at Vasylkiv, where VDV paratroopers attempted to seize the Vasylkiv Air Base but the attack was repelled.[33]
A paratrooper or military parachutist is a soldier trained to conduct military operations by parachuting directly into an area of operations, usually as part of a large airborne forces unit. Traditionally paratroopers fight only as light infantry armed with small arms and light weapons, although some paratroopers can also function as artillerymen or mechanized infantry by utilizing field guns, infantry fighting vehicles and light tanks that are airdropped together into the combat zone.
Airborne forces are ground combat units carried by aircraft and airdropped into battle zones, typically by parachute drop. Parachute-qualified infantry and support personnel serving in airborne units are also known as paratroopers.
A division is a large military unit or formation, usually consisting of between 10,000 to 25,000 soldiers. In most armies, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps.
A brigade is a major tactical military formation that typically comprises three to six battalions plus supporting elements. It is roughly equivalent to an enlarged or reinforced regiment. Two or more brigades may constitute a division.
The 1st Cavalry Division is a combined arms division and is one of the most decorated combat divisions of the United States Army. It is based at Fort Cavazos, Texas. It was formed in 1921 and served during World War II, the Korean War, the Vietnam War, the Persian Gulf War, with the Stabilization Force in Bosnia-Herzegovina, in the Iraq War, in the War in Afghanistan as well as Operation Freedom's Sentinel and Operation Inherent Resolve. As of July 2023, the 1st Cavalry Division is subordinate to III Armored Corps and is commanded by Major General Thomas M. Feltey
The 11th Airborne Division is a United States Army airborne formation based in Alaska.
Light infantry refers to certain types of lightly equipped infantry throughout history. They have a more mobile or fluid function than other types of infantry, such as heavy infantry or line infantry. Historically, light infantry often fought as scouts, raiders, and skirmishers. These are loose formations that fight ahead of the main army to harass, delay, disrupt supply lines, engage the enemy's own skirmishing forces, and generally "soften up" an enemy before the main battle. Light infantrymen were also often responsible for screening the main body of a military formation.
In military organizations, a pathfinder is a specialized soldier inserted or dropped into place in order to set up and operate drop zones, pickup zones, and helicopter landing sites for airborne operations, air resupply operations, or other air operations in support of the ground unit commander. Pathfinders first appeared in World War II, and continue to serve an important role in today's modern armed forces, providing commanders with the option of flexibly employing air assets. There was a group of pilots who were also designated pathfinders. They flew C-47 (DC-3) aircraft and were the lead planes followed by paratroop transports, used for dropping paratroopers into designate drop zones such as on D-Day, the Normandy Invasion.
The Air Assault Badge is awarded by the U.S. Army for successful completion of the Air Assault School. The course includes three phases of instruction involving U.S. Army rotary wing aircraft: combat air assault operations; rigging and slingloading operations; and rappelling from a helicopter.
The Italian Army is the land force branch of the Italian Armed Forces. The army's history dates back to the Italian unification in the 1850s and 1860s. The army fought in colonial engagements in China, Libya, Northern Italy against the Austro-Hungarian Empire during World War I, Abyssinia before World War II and in World War II in Albania, Balkans, North Africa, the Soviet Union, and Italy itself. During the Cold War, the army prepared itself to defend against a Warsaw Pact invasion from the east. Since the end of the Cold War, the army has seen extensive peacekeeping service and combat in Afghanistan and Iraq. Its best-known combat vehicles are the Dardo infantry fighting vehicle, the Centauro tank destroyer and the Ariete tank and among its aircraft the Mangusta attack helicopter, recently deployed in UN missions. The headquarters of the Army General Staff are located in Rome opposite the Quirinal Palace, where the president of Italy resides. The army is an all-volunteer force of active-duty personnel.
16 Air Assault Brigade Combat Team, known simply as 16 Air Assault Brigade from 1999 – 2021, is a formation of the British Army predominantly based in Colchester, Essex. It makes up the Air Assault Task Force, a battlegroup held at high readiness, and is the only brigade in the British Army focused on operating via parachute, helicopter and air-landing.
The Rapid Deployment Joint Task Force (RDJTF) is an inactive United States Department of Defense Joint Task Force. It was first envisioned as a three-division force in 1979 as the Rapid Deployment Force (RDF), a highly mobile rapid deployment force that could be rapidly moved to locations outside the normal overseas deployments in Europe and Korea. Its charter was expanded and greatly strengthened in 1980 as the RDJTF. It was inactivated in 1983, and re-organized as the United States Central Command (USCENTCOM).
The Regimento de Paraquedistas, based in Tancos, Portugal, is a unit of the Portuguese Army and serves as the instruction center for recruitment and training of the Portuguese paratroopers. This unit includes an entire battalion, acting as support and reserve for airborne units which contains for example, military war dogs and airborne pathfinders and an instruction battalion responsible for the forming of new paratroopers.
Operation Delaware/Operation Lam Son 216 was a joint military operation launched during the Vietnam War. It began on 19 April 1968, with troops from the United States and the Army of the Republic of Vietnam (ARVN) moving into the A Sầu Valley. The A Sầu Valley was a vital corridor for moving military supplies coming from the Ho Chi Minh Trail and was used by the People's Army of Vietnam (PAVN) as a staging area for numerous attacks in northern I Corps. Other than small, special operations reconnaissance patrols, American and South Vietnamese forces had not been present in the region since the Battle of A Shau in March 1966, when a U.S. Special Forces camp located there was overrun.
In 2009, the United States and NATO International Security Assistance Force (ISAF) coalition, along with Afghan National Army forces, continued military operations against the Taliban in Afghanistan. 2009 marks the eighth year of the War in Afghanistan, which began late in 2001. And 75th ranger regiment is also in Afghanistan as of 2018
The 17th Aviation Brigade was a military formation of the United States Army. It was originally activated at Nha Trang, Vietnam, as the 17th Aviation Group (Combat) on 15 December 1965 under the 1st Aviation Brigade. Later it moved to Tuy Hoa in November 1970 and then to Pleiku in January 1972. The group had the mission of commanding and controlling all non-divisional assets in II Corps Tactical Zone, under I Field Force. The 10th, 14th, 52d, 223rd and 268th Aviation Battalions as well as the 7th Squadron, 17th Cavalry served with the group.
The 11th Expeditionary Combat Aviation Brigade is a Combat Aviation Brigade in the United States Army Reserve. The unit's lineage can be traced to the prior lineage and insignia of the 11th Aviation Group which was last headquartered in Illesheim, Germany in 2005. It is one of two aviation brigades of Army Reserve Aviation Command. The brigade consists of a headquarters company, two Black Hawk assault battalions, and one fixed wing battalion. The brigade was activated in its current formation on 16 September 2016.
Company E, 52nd Infantry, (LRP) was a 120 man-sized long-range reconnaissance patrol unit attached to the 1st Cavalry Division (Airmobile) in Vietnam in 1967-69. Its origin begins on January 1, 1967, as "LRRP Detachment G2," 1st Cavalry Division (Airmobile). It was then redesignated "Headquarters & Headquarters Company LRRP Detachment" in April 1967, and redesignated "Company E, 52nd Infantry (LRP)" on December 20, 1967.
The Division Daguet was a French Army division formed in September 1990 in Saudi Arabia as part of France's contribution to Operation Desert Shield. The French military contribution to the allied cause to liberate Kuwait from Iraqi occupation was named Opération Daguet and its ground part was subsequently named Division Daguet. In French "Daguet" is a young brocket deer.
