Which 3D Air Force Specialty (AFS) responsibilities include the installation, maintenance, and repair of fixed and deployable air traffic, weather, ground air control, and warning radar systems?

The correct answer pertains to the responsibilities that focus specifically on the installation, maintenance, and repair of radar systems used in air traffic control, weather monitoring, ground air control, and warning systems. These duties are essential for ensuring that vital radar operations run smoothly and efficiently, facilitating aviation safety and mission success.

Ground Radar Systems as a 3D Air Force Specialty is dedicated to the various radar technologies necessary for effective air operations. This includes both fixed systems, which are typically stationed at airbases or radar installations, and deployable systems that can be transported and set up in the field as needed. This specialty is crucial for providing situational awareness to pilots and ground controllers, improving overall operational effectiveness in both peacetime and combat missions.

In contrast, the other options pertain to different aspects of military communications and electronic systems. Spectrum Operations deals with the management and allocation of the electromagnetic spectrum for various communication needs. Cable and Antenna Systems predominantly focus on the installation of cable infrastructure and antennas for data and voice communication rather than radar systems. Radio Frequency Transmission is centered around the transmitting and receiving of radio signals, again with a different scope than radar operations. Thus, Ground Radar Systems is clearly the correct answer as it directly aligns with the responsibilities mentioned in the question
