Which structure consists of the Secretariat and the Air Staff?

The structure that consists of the Secretariat and the Air Staff is the Headquarters of the Air Force. The Secretariat is responsible for formulating policies, plans, and programs related to the organization and functions of the Air Force. This includes overseeing personnel, budgetary matters, and overall administrative management.

The Air Staff, on the other hand, is composed of senior military leaders and is primarily tasked with advising the Secretary of the Air Force on military matters and implementing the policies set forth by the Secretariat. Together, these two components work to ensure the effective operation and strategic direction of the Air Force, making the Headquarters of the Air Force a pivotal element in the chain of command and operational readiness.

Other options like the Air Force Reserve, Air National Guard, and Combatant Commanders do not encompass both the administrative and operational leadership structures found within the Headquarters of the Air Force. Each of these alternatives plays a distinct role within the broader Air Force framework but does not include both the Secretariat and the Air Staff as part of their foundational structure.
