What encompasses Major Command, Field Operating Agencies, and Direct Reporting Units in the Air Force?

The correct answer is the Department of the Air Force, as it serves as the overarching organization that includes all components of the Air Force, such as Major Commands (MAJCOMs), Field Operating Agencies (FOAs), and Direct Reporting Units (DRUs).

The Department of the Air Force is responsible for organizing, training, and equipping Air Force personnel and maintaining operational readiness. MAJCOMs are the primary organizational structure within the Air Force, focusing on specific missions, while FOAs and DRUs provide specialized capabilities and support directly under theAir Force structure. This creates a cohesive environment where various units can fulfill their roles effectively while supporting the overarching mission of the Air Force.

The other options do not specifically encompass these components. The Department of Defense pertains to the entire military establishment, which includes all branches of the armed services, not just the Air Force. The Military Department refers to the branch-specific organizations within the Department of Defense, and Air Force Headquarters mainly functions as the leading management and administrative body of the Air Force but does not include the broader structural components like MAJCOMs, FOAs, and DRUs in its scope.
