During a drill, what is the purpose of a supplemental command?

A supplemental command serves to clarify a previous command. In a drill scenario, clarity is paramount to ensure that all participants understand what is expected of them and can execute their tasks effectively. Supplemental commands help to reinforce or elaborate on instructions that may have been misunderstood or vague, helping everyone to align their actions with the intended outcome of the drill.

This specificity is crucial in maintaining order and efficiency during drills, as any ambiguity can lead to mistakes or confusion, which can be detrimental in high-stakes or emergency situations. By providing clarification, a supplemental command ensures that all personnel are on the same page, thus improving the overall effectiveness of the drill. This function distinguishes it from commands given to provide additional information, mitigate distractions, or redirect focus, which have their own specific purposes but do not specifically address the need for clarity on prior instructions.
