What does the command "COVER" instruct military personnel to do?

The command "COVER" is a military order used to ensure that personnel align themselves directly with the service member in front of them, creating a straight line with proper spacing. This command is crucial during formations and drill movements, as it helps maintain the order and precision expected in military formations. By aligning with the person ahead, service members demonstrate discipline and unity, which are core values in military operations.

The other choices do not accurately reflect the purpose of the command. While standing in a straight line may be a result of the order, the emphasis is specifically on aligning with the individual in front, rather than just standing in line generally. Saluting a commanding officer is a separate protocol not related to the command "COVER," and taking a step back contrasts the directive by suggesting movement away from the specified alignment.
