Which term denotes rotary-wing aircraft designed to deliver close air support and attack roles?

• A. MAGTF
• B. Fixed wing aviation unit
• C. Riverine assault craft unit
• D. Attack helicopter

Answer: (D)

Focus on rotary-wing air power built for direct fire support. Attack helicopters are designed to accompany ground forces and deliver close air support and attack missions from the air, using weapons systems such as a cannon, rockets, and missiles, while able to hover and maneuver at low altitude to engage targets precisely where troops are operating. This combination of vertical takeoff and landing capability, battlefield mobility, and weaponry tailored for direct-fire support makes them the clear term for this role. The other options refer to organizational structures or non-rotary platforms (a Marine task force, fixed-wing airplanes, and riverine boats), which do not describe a rotary-wing system designed for CAS and attack missions.
