What FDC command is used to signify the number of rounds specified in the fire for effect has been fired?

The command used to signify that the specified number of rounds in the fire for effect has been fired is "Rounds Complete." This command is critical in artillery operations as it indicates to the Fire Direction Center (FDC) that the indicated volume of fire has been successfully executed. It ensures that all rounds have been delivered to the target as intended and allows for tracking the progress of artillery missions.

Knowing when the rounds have been completed is essential for coordinating follow-on actions, adjustments, or ceasefire commands. This is part of the established communication protocol within artillery operations, ensuring clarity and efficient management of fire support.

In contrast, the term "Splash" typically indicates that a round is about to impact, serving as a warning for personnel in the area. "Shot" confirms that a round has been fired but does not provide information regarding the completion of a specific number of rounds. "End of Mission" would signify the termination of the current fire mission but does not specifically convey that the number of prescribed rounds has been reached. Understanding these distinctions helps maintain operational effectiveness and safety during artillery missions.
