Final answer:
The command of execution in a drill command indicates the desired movement and signals when to perform the specified action. It is the second part of the command that follows the preparatory command, which outlines what the movement will be.
Step-by-step explanation:
The drill command is an oral order in military protocols that typically encompasses two key components: the preparatory command and the command of execution. The correct answer to what the command of execution does is A) Indicates the desired movement. This is the part of the command that signals the moment to carry out the movement or action that was specified in the preparatory command. For instance, in the command “Forward, march,” “Forward” serves as the preparatory command that signifies what movement is to come, while “march” is the command of execution directing the soldiers when to begin the action.
Commands and their prompt enforcement are crucial, for they shape the discipline and effectiveness of a military force. As Sun Tzu implies in his writings, consistent enforcement leads to a well-disciplined army, and a general's confidence combined with the expectation of obedience can result in mutual benefits.
