When a message needs to be transmitted to another person or incident, which term should be used?

The correct choice is relay, which refers to the action of passing information or messages from one person or unit to another. In the context of communication, particularly in emergency services or law enforcement, relaying information is essential for ensuring that all involved parties have the accurate and necessary details to respond effectively to an incident.

Properly relaying a message enhances clarity and minimizes the risks of misunderstandings, which can be crucial in high-stakes scenarios. The term conveys the concept of transferring responsibility for the message from one communicator to another while maintaining the integrity of the information.

Other terms, such as receiving poorly or transmitting too rapidly, indicate issues with communication rather than the act of sending a message. "In service" typically refers to the status of a unit or personnel being active or available, rather than the actual process of communication. Thus, "relay" is the best choice as it accurately describes the intended action in a clear and concise manner.
