How many inches apart are soldiers in close interval?

In a close interval, soldiers are positioned 4 inches apart. This specific spacing is designed to allow for tight formation and control during marches or when transitioning into combat situations while enabling soldiers to maintain effective combat readiness and cohesion as a unit. The close interval helps ensure that soldiers are close enough to communicate effectively and respond quickly while still preventing overcrowding, which could lead to confusion or reduced mobility.

This spacing reinforces the principle of maintaining an organized formation, allowing for quick movements and readiness to engage without losing the integrity of the unit structure. Other spacing options, such as 6, 8, or 12 inches, do not fit the definition of a close interval and are characteristic of other formation types that may allow for greater personal space or maneuverability, which is not the purpose during close interval formations.
