Which of the following is not a function of Marine Corps aviation?

Cargo delivery is an essential function of Marine Corps aviation, making it a key option as it pertains to logistical support and the movement of supplies and equipment. While close air support, reconnaissance, and personnel transport are integral roles, the primary focus of Marine Corps aviation is not typically categorized under cargo delivery in the same manner as supporting ground troops with air cover or providing intelligence through reconnaissance.

Close air support involves engaging enemy forces in direct support of ground troops, which aims to enhance the effectiveness of ground operations. Reconnaissance is crucial for gathering information about enemy positions and movements, allowing for informed tactical decisions. Personnel transport refers to the movement of Marines and equipment to and from operational locations, playing a vital role in mission readiness.

Cargo delivery, while important, is generally considered more associated with the logistical capabilities of support aircraft rather than the combat-focused objectives of Marine Corps aviation. This distinction highlights why this function does not align with the core mission objectives of Marine aviation.
