Which document contains the policies and procedures for USAF Services operations?

The Air Force Instruction (AFI) related to Services is the correct document that contains the specific policies and procedures guiding USAF Services operations. AFIs are crucial as they provide detailed instructions and guidelines for various aspects of Air Force operations, including the management and execution of services within the USAF. They are tailored to address the unique needs and operational methods of the Air Force, ensuring that personnel have clear standards and procedures to follow.

Referencing other options, the Joint Publication (JP) typically addresses broader joint operations and strategy between branches of the military rather than specifics for a single branch. The Air Force Manual (AFMAN) might provide supplementary technical or procedural guidelines but does not hold the same level of authority as an AFI for operational directives. Although the Department of Defense Directive (DODD) outlines policies at a higher level, it does not delve into the specific operational procedures necessary for USAF Services. Thus, the AFI is the most relevant and authoritative source for policies governing these operations.
