This instruction provides clear guidance on accountability, responsibility, and the management of supplies within the Air Force. It establishes requirements for all personnel involved in supply functions, thereby ensuring that everyone understands their role in maintaining efficient supply chain operations and adheres to the protocols set forth.

By setting forth these guidelines, AFI 23-111 helps maintain the integrity of supply operations, ensuring that resources are accounted for and utilized effectively. This is essential for operational readiness and mission success in the military context. Other available documents may cover various aspects of supply management, but only AFI 23-111 is specifically dedicated to governing supply discipline across all personnel in the Air Force.
