Which publication details Army Material Maintenance Policy?

The correct publication that details Army Material Maintenance Policy is AR 750-1. This regulation serves as a comprehensive guide outlining the policies, responsibilities, and procedures for the maintenance of Army materiel. It sets forth the framework for maintaining equipment in terms of lifecycle management, ensuring operational readiness, and the conservation of Army resources. This is essential for sustaining the Army's operational capabilities and involves directives on how maintenance is to be conducted at various levels, including organizational, direct support, and general support.

The other options, while significant in their contexts, do not specifically address Army Material Maintenance Policy. For instance, AR 600-20 focuses more on the Army Command Policy, which encompasses topics such as Equal Opportunity, command relationships, and personnel management. DA PAM 750-1 is a pamphlet that provides additional guidance and information supplementary to AR 750-1 but does not serve as the primary regulatory document. FM 27-1 deals with legal aspects of military operations, rather than maintenance policy. Thus, AR 750-1 is authoritative for establishing the procedures and standards necessary to maintain Army equipment effectively.
