What Army Regulation (AR) outlines supply policy below the national level?

The correct answer is B, AR 710-2, which specifically addresses supply policy at levels below the national level. This regulation provides the framework for managing property accountability, inventory control, and the distribution of supplies within the Army. It places significant emphasis on maintaining accurate records and ensuring that units are efficiently managing their supplies to support operations effectively.

AR 710-2 is crucial as it sets the standards for unit supply operations, including guidance on how supplies should be requisitioned, issued, and accounted for. Understanding this regulation is essential for personnel responsible for supply management, as it outlines their key responsibilities and the procedures they must follow to ensure compliance with Army standards.

The other regulations, while relevant to various aspects of Army supply and property management, do not specifically focus on supply policy below the national level. For instance, AR 700-1 covers supply policy in a broader context, AR 720-3 deals with the management of operational projects and stocks, and AR 740-1 relates to the management of Army property. Therefore, AR 710-2 is the regulation that most directly addresses the needs and guidelines for supply operations at lower levels within the Army structure.
