What message has precedence over routine traffic?

The correct choice focuses on the hierarchy established for message types within communication protocols. The term "priority" indicates a level of urgency that demands quicker processing and transmission than routine messages. In tactical communications, prioritizing certain messages ensures that critical information reaches the relevant personnel without delay, which is vital in operational settings where timely decisions can impact mission success.

Messages categorized as emergency typically have the highest precedence, but priority messages still hold significant importance and come before routine traffic in the communication protocol. This differentiation underlines the structured approach to managing communications effectively, ensuring that time-sensitive information is conveyed promptly.

Normal messages, on the other hand, are processed as routine traffic and do not require immediate attention, emphasizing the need for prioritization in tactical situations where efficiency and responsiveness are crucial.
