Which regulation contains the range safety policy for the U.S. Army and Marine Corps?

The correct choice is based on the fact that AR 385-63, titled "Policies and Procedures for Training Ammunition and Explosives," outlines the safety standards and procedures specifically related to the use of ranges and training areas for the U.S. Army and Marine Corps. This regulation establishes the required safety measures to prevent accidents and ensure the safety of personnel and equipment during training operations.

Understanding the importance of AR 385-63 highlights its role in promoting a culture of safety and adherence to guidelines when handling live ammunition and engaging in combat training. This regulation serves as a foundational document for range safety policies, ensuring that both branches operate under a unified set of safety protocols.

On the other hand, FM 21-75 is a field manual focused on various survival techniques and is not directly related to range safety policies. DA Pam 385-64 deals with ammunition and explosives safety and management rather than specific range operations. AR 600-55 primarily addresses licensing and driving regulations for military personnel, which is not focused on range safety.
