What are the two types of commands used in drill procedures?

The correct answer highlights the two fundamental types of commands used in drill procedures: the Preparatory Command and the Command of Execution.

The Preparatory Command serves as a cue to the participants, indicating that an action is about to occur. It prepares them physically and mentally, allowing them to anticipate the subsequent action. For example, if the command is "Attention," it signals to the individuals that they will soon be expected to assume a specific posture. This step is crucial as it sets the stage for a coordinated and uniform response.

The Command of Execution follows the Preparatory Command and signals the exact moment when the action should take place. In the previous example, the command “Dress right, dress” would be the Command of Execution, prompting individuals to move into the specified position simultaneously. This two-part structure is essential for ensuring a smooth and synchronized performance during drill activities.

The other options do not accurately capture the standard terminology or structure utilized in drill commands. It's important to understand the definitions and functions of these commands as they are fundamental to effective drill instruction and execution.
