Who is responsible for giving all commands on the shooting line and assisting during emergencies?

The Role of the Position Safety Officer is crucial on the shooting line, as this individual is designated to give commands to ensure safety among shooters and oversee the safe conduct of firing exercises. They are typically responsible for ensuring all range safety protocols are followed, giving commands such as "Cease Fire," and managing the situation during both regular operations and emergencies.

In contrast, while the Range Safety Officer is primarily tasked with overseeing the entire range and making broad safety decisions, the Position Safety Officer operates at a more localized level on the shooting line. The Commanding Officer and Command NCO/SNCO hold leadership roles with various responsibilities but are not specifically tasked with giving commands or managing the immediate safety of personnel on the line during shooting exercises.

Therefore, the Position Safety Officer has defined responsibilities that directly pertain to command on the shooting line and emergency assistance, making them the correct answer to this question.
