SIA CP Communications & Radio Procedures 2

Question 1

What is the NATO phonetic alphabet word for the letter 'C'?

Accepted Answer

Charlie

Answer

Charlie represents the letter C in the NATO phonetic alphabet, used in security radio communications to spell out names, vehicle registrations and other key information clearly.

Question 2

What does 'roger' mean in radio communications?

Accepted Answer

Message received and understood

Answer

'Roger' confirms that a transmission has been received and understood; 'wilco' would indicate that the instruction will be complied with; they are distinct terms.

Question 3

What is a 'secure' radio channel and when is it used?

Accepted Answer

An encrypted channel that prevents unauthorised monitoring, used when sensitive operational information must be transmitted

Answer

Encrypted radio channels prevent eavesdropping by hostile parties; sensitive details such as the principal's location, route or threat information should only be transmitted on secure channels.

Question 4

What is the purpose of a 'code word' system in CP communications?

Accepted Answer

To transmit sensitive information discreetly without revealing meaning to anyone monitoring the channel

Answer

Code words allow the team to communicate specific situations — threat levels, extraction orders, all-clear — without revealing operational meaning to hostile parties who may be monitoring.

Question 5

What communication method serves as backup if primary radio fails?

Accepted Answer

Pre-agreed mobile phone numbers, signal codes or alternative radio frequencies

Answer

Every CP operation must have backup communications — mobile phones, pre-agreed signals or secondary radios — so that team communication is never entirely lost during an operation.
