The Mission Commander is the overall leader of the operation, responsible for directing the mission and ensuring the Sensor Operations Team functions effectively. This role involves planning and coordinating activities, maintaining a clear picture of the mission’s status, allocating resources, monitoring progress and safety, and communicating with higher command to keep everyone informed and aligned. The other tasks listed—routing data to ADSI, providing the TACSAT data link, or managing environmental controls—are specialized technical or support duties carried out by other crew members or sections, not by the Mission Commander.

The ADSI Server is designed to operate within tactical data link networks, where real-time digital information is shared among military platforms. These networks connect aircraft, ships, and ground units to exchange track data, positions, statuses, and other tactical information to create a common operating picture. That data-sharing role aligns with what the ADSI Server does, making it a participant in tactical data link networks. It isn’t meant for voice-only networks, which don’t handle the same data payloads, nor for weather data networks or power distribution networks, which serve different purposes and data types.

Leading the response is about command and control on the scene. The Incident Controller is the person with the authority to direct all actions, set incident objectives, prioritize tasks, allocate resources, and ensure the safety and welfare of responders. This role maintains overall situational awareness and makes the strategic decisions that shape how the response unfolds. The CRC Manager provides broader support to the CRC functions and resources, but does not take on the on-scene leadership role. The Liaison Officer focuses on coordinating with external agencies and stakeholders, ensuring information flows between groups. The Communications Officer handles messaging and information management, keeping people informed but not directing incident tactics.

Sensor operations rely on four core roles that cover the essential functions: operating and monitoring the sensors, providing the information and communications technology support, handling the processing and exploitation of sensor data, and supervising the team. The four roles listed—AST/SSO, ICT, EPT, and ST/MSO—together map to those functions, giving a complete SOT makeup. AST/SSO handles the day-to-day sensor operation and surveillance tasks, ICT ensures the data and systems stay connected and integrated, EPT takes the sensor outputs and converts them into usable information, and ST/MSO provides leadership and coordination for the team. This combination ensures sensors are run effectively, data flows smoothly, information is derived efficiently, and the team stays organized. Other options include roles that are not designated as part of the main Sensor Operations Team components or omit one of these essential functions, so they don’t form the full SOT set.
