The fighter check-in brief is transmitted to which entity?

• A. Pilot
• B. Observer controller
• C. Ground crew
• D. Air traffic control

Answer: (B)

In close air support coordination, the fighter check-in brief is sent to the observer controller. The observer controller acts as the air-ground liaison, receiving the flight’s check-in to verify mission details (identity, location, altitude, intent) and then passing the information to the forward observer and JTAC. This ensures everyone on the ground and in the air shares the same picture and can deconflict airspace and coordinate targets effectively. The other options don’t fit because pilots don’t route this brief to themselves, ground crew aren’t the primary coordinators of air-to-ground fires, and air traffic control handles sequencing and routing rather than tactical air coordination.
