Which capability is associated with the rapid insertion and extraction of personnel?

The capability most closely associated with the rapid insertion and extraction of personnel is helicopter transport. Helicopters are specifically designed for such operations, allowing for swift movement of troops into or out of an area, often in challenging terrains where ground vehicles cannot easily operate. This agility and speed are crucial in situations requiring immediate tactical responses, such as during combat operations, search and rescue missions, or humanitarian assistance.

Helicopter transport also provides flexibility in various operational contexts, enabling forces to operate quickly and effectively across diverse environments. This capability is essential for operations that depend on speed, surprise, and the ability to operate in confined spaces. Other options, while related to various aspects of logistical support or troop movement, do not focus solely on the defined rapid insertion and extraction role that helicopter transport fulfills.
