Which system provides the interface between the Army and tactical air support agencies of other services in planning, evaluating, processing, and coordinating air support requirements and operations?

• A. Theater Air Control System
• B. Army Air-Ground System
• C. JTAC
• D. JFO

Answer: (B)

The question tests understanding of which structure links Army ground forces with the tactical air forces from other services to plan, evaluate, process, and coordinate air support. The Army Air-Ground System is that interface. It provides the procedures, communications, and relationships needed to integrate air power with ground operations, including how air support requests are made, evaluated, and executed, and how air and ground forces coordinate target development and airspace deconfliction across service boundaries.

The Theater Air Control System handles theater-wide airspace control and coordination of air operations, but not the specific Army-to-joint air support interface. The other options refer to individuals who control or observe air support (such as JTAC or JFO) rather than to the overarching system that ties Army and joint air assets together.
