Which document outlines the safety responsibilities of the RSO?

The document that outlines the safety responsibilities of the Range Safety Officer (RSO) is AR 385-63. This regulation provides detailed instructions and guidelines on range safety, ensuring that personnel involved in training exercises are aware of their responsibilities and the protocols necessary to maintain a safe environment.

AR 385-63 specifically addresses the safety management system within a training range, emphasizing the RSO's critical role in overseeing operations, enforcing safety standards, and mitigating risks associated with live-fire training. It covers procedures for range operations, incident reporting, and the required qualifications for RSOs, helping them to effectively manage potential hazards and ensure compliance with safety regulations.

In contrast, other documents mentioned serve different purposes. For instance, FM 7-22 discusses physical fitness, DA PAM 385-63 serves as a supplementary guide to AR 385-63, and FM 3-22.9 focuses on the specific use of pistols in military operations. Understanding the unique content of each document helps clarify why AR 385-63 is the definitive resource for RSO safety responsibilities.
