Which of the following is NOT a type of Air Coordination Measure (ACM)?

Combat Air Patrol (CAP) is a mission or operation where aircraft are deployed to protect a specific area or assets from air threats. While it plays a crucial role in air defense and tactics, it does not fall under the category of Air Coordination Measures (ACM). ACMs are typically designed to manage and control airspace usage, ensuring safety and efficiency in aviation operations.

In contrast, Air Corridor refers to a designated path for aircraft to follow, which facilitates orderly traffic flow in specific areas. Restricted Operating Zone (ROZ) is a designated airspace that restricts entry for safety or security reasons, often implemented to protect military operations or sensitive areas. Stand Alone might refer to specific operational measures or systems that function independently within the airspace management context.

Since Combat Air Patrol focuses on engagement and operational capabilities rather than the coordination of airspace usage, it is correctly identified as not being a type of Air Coordination Measure.
