What describes a Perimeter Defense?

A perimeter defense is characterized by a defensive strategy that focuses on securing all points around a specific area or installation. This concept emphasizes creating a defensive barrier that protects against external threats by establishing security measures along the entire boundary of the area being defended. The intent is to create layers of security that can detect, deter, and respond to incursions effectively, thereby safeguarding the assets contained within the perimeter.

In contrast to the other options, a perimeter defense does not rely on central command as its core strength, do not involve retreat strategies, nor serve as an offensive tactic against enemy forces. Instead, it is all about creating a robust defensive posture that maintains control over the space surrounding critical assets.
