Which two supply references cover practices for US government property?

The correct reference for the practices governing US government property is found in AFI 23-101 and DoDI 4140.01.

AFI 23-101, titled "Air Force Materiel Managementpolicy," serves as the foundational document for materials management and logistics within the Air Force, detailing how to manage and track government property efficiently. It establishes procedures for the supply chain and outlines responsibilities for various aspects of property management, which is essential for maintaining accountability and operational readiness.

DoDI 4140.01, referred to as the "DoD Supply Chain Material Management," complements AFI 23-101 by providing overarching DoD policies and guidance on managing material and inventory across all military branches. This instruction focuses on the principles of logistics and supply chain management while ensuring that government property is managed in accordance with established standards across the Department of Defense.

Together, these references provide a comprehensive framework for ensuring the effective and responsible management of US government property, addressing both specific Air Force needs and broader Department of Defense guidelines.
