Which agency oversees the United States Air Force Services Program?

The Air Force Services Agency is the correct answer because it is specifically tasked with overseeing the United States Air Force Services Program. This agency is responsible for developing and managing policies, programs, and resources that support airmen and their families, enhancing their quality of life through various services, activities, and recreational opportunities. By focusing on the unique needs and requirements of Air Force personnel, the Air Force Services Agency ensures that the Services Program is effectively implemented across various installations.

The other agencies mentioned do play significant roles within the broader context of the military and support services, but they do not have the same direct oversight over the specific operations and policies related to the Air Force Services Program. For example, the Department of Defense oversees all branches of the military, including budget decisions and overall policies but does not manage specific programs at the level of individual services. The National Guard Bureau is concerned with the National Guard's operations and policies rather than the air force active-duty services. The Air Force Academy primarily focuses on the education and training of future Air Force leaders, rather than the management of service programs.
