What is the distance between individuals of a squad in line at close interval?

The correct answer reflects a standard practice in military formation, particularly when discussing squad formations in close intervals. In a close interval, individuals in a squad are positioned in a manner that reduces the distance between them, allowing for efficient movement and communication while maintaining formation integrity. Specifically, the distance between individuals in a squad at close interval is set at 4 inches.

This spacing is crucial as it allows for a compact formation, which can be beneficial in certain tactical scenarios. Additionally, this distance helps maintain cohesion while allowing for ease of movement, ensuring that squad members can still operate effectively without being too far apart from one another.

While the other options suggest varying distances—such as 1 inch, 2 feet, and 6 inches—these measurements do not align with the established military standard for close intervals. The chosen standard of 4 inches strikes a balance between proximity and operational effectiveness.
