Which of the following is considered an Airspace Reference Measure?

An Air Control Point is classified as an Airspace Reference Measure because it serves as a designated point used for coordinating air operations. This measure is essential for ensuring effective communication and control among various air units operating in the same airspace, facilitating the deconfliction of aircraft and the execution of tactical maneuvers.

Air Control Points allow commanders and operators to reference specific locations for mission planning, execution, and coordination, helping to enhance situational awareness and safety during operations involving both air and ground forces. Effective use of Air Control Points can optimize air support and operational effectiveness in a military context.

In contrast, other options like the Restricted Operations Zone and Exclusion Zone, while significant, relate more to regulating activities within specific regions rather than serving as operational coordination points. The Battlefield Coordination Line, while also important for air-ground operations, specifically focuses on the boundary for coordinating air support, rather than serving as a specific reference point for operational control.
