What action should follow the completion of a transmission?

The correct action following the completion of a transmission is to use the proword 'Out.' This proword indicates that the speaker has finished their transmission and is not expecting a reply. It serves to clarify communication, ensuring that all parties understand that the message has concluded. Using 'Out' helps maintain clarity and proper protocol in tactical communications, as it prevents any ambiguity regarding whether the transmission is still ongoing or if the operator has completed their communication.

In tactical situations, where clear and concise communication is vital, signaling the end of a message allows other operators to know when they can speak or respond, optimizing communication flow within a unit. This practice helps reduce confusion and keeps operations running smoothly.
