Which unit is designated to monitor critical voice frequencies and maintain communications guard?

• A. Communications Unit
• B. Situation Unit
• C. Operations Unit
• D. Planning Unit

Answer: (A)

The concept being tested is how the Communications Unit keeps radio communications running for command and control. This unit designs and maintains the communications plan, continuously monitors the primary and critical voice frequencies, and keeps a communications guard—a backup listening channel—to ensure there’s always a channel available if the main net has issues. In practice, they assign and manage radio nets, coordinate with operators, and handle frequency use to prevent gaps in contact. The other units focus on gathering incident information, directing field operations, or planning, rather than maintaining and safeguarding communications nets.
