Who holds the position of military head of the Air Force?

The Chief of Staff of the Air Force is the military head of the Air Force, providing leadership and strategic direction to all Air Force operations and personnel. This position is the highest-ranking officer in the Air Force and is responsible for the readiness, training, and equipping of all Air Force members to fulfill their duties in service to the nation.

In contrast, the Secretary of the Air Force is a civilian position that focuses on overseeing the Air Force's administration and budgetary aspects. The Undersecretary of the Air Force serves in a supporting role and may act on behalf of the Secretary when needed but does not hold the highest military rank. The Chief Master Sergeant of the Air Force is the highest enlisted member, providing insight and guidance on enlisted issues but does not have the same command authority or responsibilities as the Chief of Staff.
