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

The section that outlines radio frequencies, call signs, and passwords is the Command and Signal part of the five-paragraph order. This section is critical as it provides the necessary communication guidelines for the operation, ensuring that all units involved can effectively coordinate and share important information. By specifying radio frequencies, it enables clear and direct communication between personnel, which is essential in a combat environment. Additionally, the inclusion of call signs helps to maintain operational security and reduces the risk of confusion during missions. Passwords further enhance security by ensuring that only authorized personnel can communicate or receive sensitive information. Thus, the Command and Signal portion plays a vital role in the overall command structure and operational effectiveness.
