When should you omit the word "over" in a radio transmission?

Omitting the word "over" in a radio transmission is appropriate when no reply is expected. The use of "over" indicates the end of a transmission and the expectation of a response. In situations where the sender does not anticipate a reply, using “over” would be unnecessary and could lead to confusion regarding whether a response is needed.

In contexts where a transmission concludes a communication or gives final instructions, the omission of "over" aligns with standard communication practice, as it emphasizes that the message is complete. However, the correct focus here is on situations where ongoing dialogue is not expected.

Urgent messages require clarity and brevity, but the inclusion of "over" might not detract from the urgency itself; however, the context here suggests that the priority is on whether a response is necessary. Different operational protocols exist with military aircraft, but the key is recognizing that the word "over" signals a two-way communication expectation, which is not needed if a reply is not anticipated.
