What is meant by 'normal interval' in military formations?

The term 'normal interval' in military formations refers specifically to the lateral space between soldiers when they are standing in a formation with their arms extended to shoulder height. This spacing allows for clear visibility, movement, and adherence to military standards during drills and formations. It ensures that each soldier has enough room to execute movements without encroaching on another’s space, which is crucial during inspections, ceremonies, or any formal display of military precision.

This definition is critical for maintaining order and discipline within formations, as it promotes efficiency and a tidy appearance. Knowing the correct spacing is essential for drill team members to perform maneuvers smoothly without any disruption. It emphasizes not just physical spacing but also the concept of personal space, coordination, and synchronization which are vital in military drills.
