Who is the appointing official for a munitions accountable systems officer (MASO) on an Air Force installation?

The appointing official for a munitions accountable systems officer (MASO) on an Air Force installation is the wing commander. This is due to the critical nature of munitions management and accountability within the Air Force, which falls under the operational oversight of the wing level. The wing commander is responsible for the overall mission accomplishment and ensures that all processes related to munitions are conducted according to regulations and standards.

By having the wing commander in this role, it establishes a high-level authority that ensures munitions are properly managed, accounting protocols are followed, and all personnel involved are adequately trained and supervised. The wing commander has the requisite authority to enforce compliance and to allocate resources effectively, which is key for maintaining safety and operational readiness.
