The site survey team should give radio checks every ________ minutes.

The site survey team should conduct radio checks every five minutes to ensure continuous communication and situational awareness during CBRN reconnaissance operations. Frequent radio checks are critical for maintaining contact between team members, particularly in environments where hazards may impact operations. This regular communication helps to verify that all team members are in a safe and operational state, facilitates the sharing of vital information, and allows for the prompt identification of any problems that may arise during the reconnaissance activities. Establishing a five-minute interval strikes a balance between ensuring effective communication without overwhelming team members, making it the standard practice in these operations.
