In the "Dress right, dress" command, what is the proper action for a cadet?

The command "Dress right, dress" is a crucial instruction in the context of military formations and inspections. When this command is given, the correct action for a cadet involves raising the left arm to shoulder height and extending it horizontally. This action serves as a visual cue to establish proper alignment with the individual to the left, allowing each person in the formation to gauge their spacing and alignment accurately.

By turning the head to the right, cadets ensure that they are maintaining awareness of their fellow cadets and their respective positions in formation. This position is essential for maintaining uniformity and discipline, which are core principles in military training.

The other options do not fulfill the requirements of the command. Standing at ease with arms relaxed does not provide the necessary alignment. Marching to the right does not adhere to the command and disrupts the formation. Aligning the body to the left and turning heads lacks the proper movement of raising the arm, which is essential in this context. Thus, option B accurately captures the proper response to the command.
