What is the marching step size while in parade rest?

In parade rest, members of a formation stand in a relaxed position while maintaining military bearing. The correct marching step size while in parade rest is 10 inches apart from each foot. This distance allows for a comfortable stance that still respects the principles of military precision and discipline. The 10-inch spacing ensures that personnel can move smoothly into attention with a proper formation and maintain an appropriate distance which is conducive to both maneuverability and an organized appearance.

Understanding that the spacing in other options—15 inches, 20 inches, or 30 inches—would either compromise the neatness of the formation or make it more challenging to align properly during movements is crucial. It's important that cadets maintain the established standard as part of their training and drill practices.
