What are the supply references that outline practices for United States government property?

The correct choice identifies AFI 23-101 and DoDI 4140.01 as the supply references that govern practices for United States government property. AFI 23-101, titled "Supply Support Management," provides comprehensive guidance on supply chain management and the responsibility and accountability pertaining to government property. This ensures that all personnel involved with property management understand the procedures for acquisition, maintenance, inventory, and utilization of assets.

DoDI 4140.01, which is the Department of Defense instruction for the management of supply chain systems, complements the AFI by outlining broader policies regarding logistics and material management. It establishes a framework for efficient and effective support of mission requirements, emphasizing responsible stewardship of government property.

Together, these documents ensure that proper protocols are followed for the management and maintenance of United States government property, fostering accountability and efficiency within military supply chains.
