What announcement does the gunner make when laid for a fire mission?

When the gunner is laid for a fire mission and makes the announcement, "Set, ready," it signifies that the crew is prepared to execute the firing commands. This phrase informs the crew and the rest of the unit that the weapon system has been properly aligned and configured for the specific target and mission parameters. It is a crucial step in ensuring that all crew members are aware of the current status of the cannon, promoting safety and readiness before a fire mission is executed.

In this context, saying "Set, ready" establishes a sense of coordination and communication among the crew. Effective communication is essential in artillery operations, as it helps avoid confusion and ensures that everyone is on the same page regarding the status of the operation.

Other announcements, while they may be relevant in other contexts, do not convey the same specific readiness for a fire mission. The focus on "Set, ready" emphasizes the importance of being prepared and signaling to the crew that they can proceed with firing when commanded.
