Which part of the five-paragraph order details radio frequencies, call signs, and passwords?

The correct choice regarding the part of the five-paragraph order that encompasses radio frequencies, call signs, and passwords is indeed Command and Signal. This section is designed to convey all the necessary communication protocols for the operation.

Including radio frequencies in this section allows all units to coordinate effectively, ensuring that communication is clear and reliable during the execution of missions. Call signs are vital for maintaining operational security and clarity, allowing personnel to identify each other without revealing actual names or units over the airwaves. Additionally, passwords can be crucial for verifying identity and ensuring that only authorized personnel are privy to sensitive information.

By organizing this information under Command and Signal, it ensures that all personnel involved in the mission are aware of how to communicate and maintain security protocols. This helps facilitate effective communication and coordination, which are critical in operations where timely and accurate information exchange can greatly influence mission success.
