Air Assault
Overview
Air Assault (空中强襲) is a military operational concept in which ground forces, equipment, and firepower are rapidly inserted into the enemy's rear or key objective areas using rotorcraft such as helicopters and vertical takeoff and landing aircraft, then complete their mission by surprise and either withdraw or secure a foothold. Unlike traditional airborne operations that drop forces by parachute, its distinguishing feature is that aircraft can land and take off again, allowing flexible recovery of forces, reinforcement, and resupply. As a core pillar of modern maneuver warfare, it enables tactics that bypass enemy defensive lines through speed and vertical maneuver and concentrate combat power at decisive points.
Key Details
Concept and Difference from Airborne Operations
Whereas airborne operations have a strongly strategic character, dropping large forces by parachute all at once, air assault has a more tactical and operational character, in which units at battalion or brigade level and below use helicopter formations to land forces at landing zones (LZs) over multiple waves. In addition, while air mobility focuses on simple transport, air assault is distinguished in that it is a combat action premised on assault, surprise, and firepower integration. Recently, as the means have expanded to include tiltrotor aircraft and unmanned transport aircraft, the boundaries are becoming blurred.
Origins and History
Air assault's roots can be found in assault operations using gliders and small transport aircraft late in World War II and in helicopter medical evacuation and search operations during the Korean War. The concept was properly established in the 1950s when the U.S. Army reorganized the 101st and 82nd Airborne Divisions into an air mobility system. During the Vietnam War, the 1st Cavalry Division's "Air Cavalry" and the 1965 Battle of Ia Drang showed the prototype of large-scale helicopter assault. Later, U.S. air assaults in Grenada in 1983, Panama in 1989, the Gulf War in 1991, and the Iraq War in 2003 were used as key means of seizing the initiative in the early stages of operations. The Soviet Union and Russia also developed their own air assault doctrine centered on the Airborne Forces (VDV), and NATO countries such as the United Kingdom and France maintained helicopter assault brigades and regiments in their standing forces.
Organization and Equipment
A typical air assault unit consists of transport helicopters (UH-60, CH-47, NH90, etc.), attack helicopters (AH-64, Mi-24, etc.), light helicopters for reconnaissance and command, and the aviation battalion and ground maneuver battalions that control them. Forces are organized around lightly armed infantry and highly mobile mortars, anti-tank weapons, and anti-aircraft weapons, and because their organic firepower is limited, close integration with artillery, close air support, and unmanned reconnaissance is essential. Recently, tiltrotors (V-22, V-280) and medium unmanned transport aircraft are emerging as next-generation assault means.
Operational Procedure
Operations usually proceed in the following order: ① intelligence and weather analysis and selection of landing zones; ② opening air routes and fire preparation; ③ assault by the advance party; ④ assault and reinforcement by the main force; ⑤ defense of the foothold or strike on the objective; ⑥ withdrawal and resupply. To avoid enemy air defense threats along air routes, multiple air routes and dispersed landing zones are used, and infiltration at night or in bad weather increases surprise. Commanders use airborne command posts and digital operational maps to solve the command-and-control problem of existing simultaneously on the ground and in the air.
Vulnerabilities and Limitations
Air assault units depend absolutely on the survivability of helicopters. As threats diversify to include man-portable air-defense systems (MANPADS), heavy machine guns, and recently small drones, they can suffer great losses during the approach to landing zones. Bad weather, reduced payload in high-altitude and high-temperature environments, and limited organic firepower and resupply capability are also structural weaknesses. Accordingly, air assault is generally employed in a limited manner under conditions in which large-scale fire support and electronic warfare and air defense suppression are secured.
Air Assault in South Korea
The South Korean military has maintained air assault capabilities centered on the Army Aviation Operations Command, the 1st Airborne Brigade, and the Special Warfare Command. With the introduction of Surion (KUH-1) and Surion-series utility helicopters, CH-47D, and AH-64E Apache, it has strengthened transport and attack capabilities and has regularized combined maneuver training that combines air assault and airborne operations. The mountainous terrain and limited road network of the Korean Peninsula are evaluated as factors that increase the value of helicopter maneuver.
Latest Trends
The biggest change in 2024–2025 is that small drones and electronic warfare are changing the survivability calculus of air assault. In the Ukraine war, Russian airborne forces suffered great losses in the initial assault stage, and as FPV drones threatened landing zones and low-altitude air routes, countries are adopting dispersed landing, night maneuver, integration of electronic warfare and counter-drone systems, and unmanned prior reconnaissance as standard procedures. The U.S. Army selected Bell's V-280 in the Future Long-Range Assault Aircraft (FLRAA) program and named it MV-75 in 2025, pursuing a transition to a tiltrotor-based high-speed, long-range assault system, and in the Pacific theater, "dispersed maritime and island assault" training combined with distributed deployment and multi-domain operations concepts is increasing. The South Korean military is also pursuing both manned-unmanned combined air assault linked with drone-bot combat systems and the introduction of equipment to enhance helicopter survivability. Overall, air assault is trending toward redefinition from a "large-scale helicopter wave" to "dispersed, covert, unmanned-collaborative vertical maneuver."
