What is one of the four categories of drill commands?

The correct category of drill commands is general. General commands are fundamental and cover a wide array of movements and formations used in drill and ceremony. They are designed to be clear and easily understood by all members of the unit, ensuring that everyone responds consistently and correctly. This category includes commands that may involve marching, facing movements, or general formations.

The term "supplemental" typically refers to commands that might be used in addition to primary commands but does not categorize the core types of drill commands. Other choices like "sergeant," which designates a rank rather than a command type, and "quick," which refers to the pace at which a command should be executed, do not specifically identify a category of commands within drill practices.
