Which of the following are the three engagement zones applicable to DCA missions?

In Defensive Counter-Air (DCA) operations, engagement zones play a crucial role in determining how forces are utilized to protect airspace. The correct choice includes three distinct zones: High Risk Engagement Zone (HREZ), De-conflicted Engagement Zone (DEZ), and Low Risk Engagement Zone (LREZ).

The High Risk Engagement Zone is where the threat is considered to be the most significant, often involving high-value assets that require immediate and decisive action. This zone requires careful coordination and rapid response to mitigate threats effectively, as it is where enemy action is most likely to occur.

The De-conflicted Engagement Zone is vital to ensuring that operations can be carried out without interference from friendly forces. This zone serves as a buffer where different assets can operate simultaneously, minimizing the risk of fratricide and ensuring smooth operations between various missions and platforms.

The Low Risk Engagement Zone is characterized by a lower probability of encountering threats. Forces operating in this zone can often engage in operations with a more relaxed posture, focusing on less immediate concerns while still maintaining the ability to respond to emerging threats.

Together, these zones form a comprehensive framework for situational awareness and response in DCA missions, ensuring effective use of resources and protection of critical assets. The terminology and
