Which of the following is NOT a type of engagement zone for DCA?

The correct answer is ARES because it does not represent a recognized type of engagement zone in the context of Defensive Counter-Air (DCA) operations. In DCA, various engagement zones are defined to categorize the operational space and identify the areas of responsibility for air defense systems.

DEZ stands for "Decision Engagement Zone," which refers to an area where engagement decisions are made, often within close proximity to a main threat, allowing fighters to intercept hostile targets effectively.

LREZ is known as the "Low Risk Engagement Zone," which emphasizes areas where the likelihood of a threat attack is minimized, allowing for safer operations for friendly forces.

HREZ stands for "High Risk Engagement Zone," highlighting areas that are more susceptible to threats, where active defense measures are crucial to combating potential attacks.

In contrast, ARES does not align with the established terminology used in DCA, making it the correct answer as the one that is not a type of engagement zone relevant to this context.
