What is included under Internal airfield communication in Airbase Functions?

Internal airfield communication in the context of airbase functions primarily involves the coordination of unit movements. This encompasses the real-time communication necessary for managing the movements of aircraft, personnel, and equipment on the airfield. Effective coordination ensures that all units operate safely and efficiently, facilitating the scheduling of takeoffs, landings, and ground handling operations.

The other options, while important in their respective contexts, do not specifically pertain to the internal communication functions of an airfield. Communications infrastructure planning focuses on the broader framework that supports communication systems, rather than the specific internal interactions needed for unit movement. Execution of tactical operations relates more to how operations are carried out in the field rather than the internal communication process. Maintenance of classified material deals with security and information protection, which is separate from the day-to-day communication operations required for coordinating activities on an airfield.
