What is the role of a Range Safety Officer (RSO) during a training event?

The role of a Range Safety Officer (RSO) during a training event is crucial for maintaining a safe environment for all personnel involved. The primary responsibility of the RSO is to monitor safety and enforce range rules. This includes ensuring that all participants adhere to established safety protocols, conducting briefings on rules and emergency procedures, and maintaining an oversight presence to manage any potential risks during the event.

The RSO acts as a central figure in preventing accidents and incidents by being vigilant and aware of the training dynamics, thus promoting a culture of safety among participants. Their authority allows them to intervene if safety violations occur, ensuring the training is conducted effectively without compromising the safety of personnel.

While other roles, such as supervising logistics operations or leading physical fitness sessions, are important in their own contexts, those duties do not specifically relate to the immediate safety concerns on the range. Conducting after-action reviews is also important for learning and improvement following an event but does not directly relate to the RSO's core responsibilities during the active training. Hence, the primary focus of the RSO's duties is to monitor safety and enforce range rules, making this the correct answer.
