Who contacts Range Control for the radio brief?

The correct choice identifies the roles of the Range Operations Incident Commander (ROIC) and the Range Safety Officer (RSO) as the individuals responsible for contacting Range Control for the radio brief. This process is essential because it ensures that both safety and operational procedures are communicated effectively before any training activities commence on the range.

The ROIC is typically responsible for the overall operation of the range and coordinating all aspects of range usage, while the RSO focuses on ensuring safety protocols are followed during operations. By having both roles involved in contacting Range Control, it enhances the communication of crucial details about the upcoming activities and ensures that all safety considerations are addressed.

This approach also aligns with established protocols within range operations, emphasizing the importance of collaboration between leadership and safety personnel to maintain a secure and organized training environment.
