Which officer coordinates field and sustainment-level maintenance operations?

The officer who coordinates field and sustainment-level maintenance operations is typically the Aviation Material Officer. This role is focused on the management and oversight of aviation maintenance activities, ensuring that aircraft and aviation equipment are effectively and efficiently maintained. The Aviation Material Officer is responsible for coordinating resources, logistics, and maintenance support to sustain operations and readiness in the field. This includes overseeing maintenance schedules, supply chain requirements, and ensuring compliance with maintenance standards.

Other roles mentioned serve different functions within aviation and personnel management. The Master Gunner, for instance, is primarily focused on gunnery training and operations, while the Standardizations Officer concentrates on ensuring adherence to standards and procedures across the unit. The Flight Surgeon, on the other hand, is responsible for the health and medical readiness of aircrew and aviation personnel, rather than maintenance operations. Thus, the Aviation Material Officer is the key figure in coordinating maintenance efforts, making this the correct choice.
