How does MARSA apply to air traffic control (ATC)?

The correct answer emphasizes that Air Traffic Control (ATC) is not responsible for determining which aircraft enter Special Use Airspace (SUA) when Military Appropriated Radar Service (MARSA) is in effect. MARSA allows military aircraft to operate in a particular way where they can self-separate and manage their own spacing and procedures. This means that when MARSA is in effect, military operations can proceed without ATC interference, thus relieving ATC from the responsibility of coordinating their entry or separation from SUA.

In this context, the military retains the authority to manage their aircraft within defined airspaces, ensuring that operations can continue efficiently while ATC focuses on civilian traffic to maintain overall airspace safety. This illustrates the unique coordination between military operations and civilian air traffic systems while ensuring safety remains a priority.
