What does the term Air Assault refer to?

The term "Air Assault" specifically refers to the movement of forces by rotary-wing aircraft. This tactical method involves the use of helicopters to transport soldiers and equipment to the battlefield quickly, enabling swift responses to enemy activity, securing terrain, and providing support to ground units. It emphasizes the integration of aerial platforms and ground forces to achieve strategic objectives efficiently.

Air Assault operations are characterized by their speed, surprise, and the ability to rapidly project combat power into an area without the constraints typically associated with ground maneuvers. This capability is especially vital in modern warfare, where time and tactical flexibility can significantly impact the outcome of engagements.

The other options refer to different military concepts: using ground forces pertains to traditional ground combat strategies; engagement by airstrikes focuses on delivering ordnance from fixed-wing aircraft; and recovery operations post-battle deal with retrieving personnel and equipment after conflicts have occurred. Each of these options represents its distinct operation or tactic, separate from the specific definition of Air Assault.
