What does the command "At My Command" do?

• A. It signals cessation of fire.
• B. It restricts firing time by allowing the FDO to control the time of firing from the FDC.
• C. It automatically schedules firing at a fixed interval.
• D. It adjusts elevation automatically.

Answer: (B)

The main idea here is control of when a fire mission actually executes. When the command is given, the Fire Direction Officer at the Fire Direction Center holds the firing data and determines the exact moment the guns will fire. The crew will not shoot on their own; they wait for the explicit release. This timing control is crucial for coordinating with observations, target updates, and other elements of the battle plan, as well as for safety.

That’s why this option is the best: it explicitly transfers the moment of firing to the FDO, ensuring the time of firing is chosen from the FDC rather than automatic or scheduled by the system. It isn’t a signal to stop firing, it doesn’t schedule firing at a fixed interval, and it doesn’t adjust elevation automatically.
