Communications & Radio Procedures Flashcards

What is 'hand signal' communication and when is it used in CP?

Answer: Pre-agreed visual signals used when radio silence is required or radio communications are unavailable

Hand signals allow silent communication between team members in situations where radio use would alert a threat actor or draw attention; they must be pre-agreed and practised to be effective.

What is a 'comms-out' drill and why is it practised?

Answer: A rehearsal of procedures the team follows when all communications fail, ensuring they can still protect the principal

A comms-out drill ensures team members know their default actions if communications fail completely — last known plan, fallback positions, silent procedures — preventing paralysis in a real failure.

What does 'stay off the net' mean in radio communications?

Answer: Do not transmit on the radio channel as it is in use for an important communication

'Stay off the net' instructs all non-essential team members not to transmit, keeping the channel clear for an ongoing priority communication or active incident.

What is the importance of a 'comms plan' in international CP operations?

Answer: Different countries have different radio frequencies, regulations and networks; a comms plan ensures the team has legal, functional communications in each jurisdiction

In international CP, radio frequencies, licences and network availability vary by country; a comms plan addresses these differences to ensure continuous, legal communications throughout the operation.

What is the meaning of 'priority traffic' in a radio network?

Answer: A transmission that takes precedence over all other traffic due to its urgent operational importance

Priority traffic is an urgent transmission — such as a threat warning or medical emergency — that takes precedence; other users must cease transmission immediately to allow it through.

Why is 'plain language' increasingly preferred over code systems in many CP operations?

Answer: It reduces the risk of misunderstanding caused by forgetting codes under stress and is faster when code recall fails

Under extreme stress, code systems can fail; plain language ensures the message is understood even if a code is forgotten, though it must be used carefully on open channels to avoid disclosing sensitive information.
