What is the purpose of the Threat Zone in the three-layer zone of defense?

The purpose of the Threat Zone in the three-layer zone of defense is to serve as the innermost layer of defense. This zone is critical because it is where immediate threats are likely to present themselves. It represents the area that requires the highest level of vigilance and preparation, as it is where security personnel must be prepared to engage actively with a potential threat. Being the innermost layer means it is the first line of defense against those who may wish to cause harm, thus necessitating a focused and proactive approach to security measures.

While evaluating potential threats, classifying contact situations, and monitoring general surroundings are important aspects of security operations, they pertain more to the analysis and situational awareness that happens outside of the Threat Zone. The distinction lies in the Threat Zone being the immediate area where the most direct and urgent response is required. Understanding this concept is vital in security operations, as it highlights the layered approach to defense that is necessary to effectively mitigate risks.
