Which positions are responsible to the AST on the sensor operating team?

The correct answer identifies the positions that are specifically tasked with responsibilities to the AST (Air Support Team) within the sensor operating team. The roles of ICT (Information Coordination Team) and EPT (Engagement Planning Team) are integral in ensuring effective communication and coordination of sensor-related information and actions. The ICT manages the data flow and ensures that all necessary information is available for the team to support air operations effectively. Meanwhile, the EPT focuses on planning and execution strategies that utilize the collected sensor data to enhance mission success. Both positions play critical roles in facilitating the operational effectiveness of air support through the use of sensors.

The other listed options do not accurately represent roles that directly report or are responsible to the AST in this context. While roles like ABM (Air Battle Manager) and SL (Section Lead) may work closely with the AST, their specific functions are distinct from the direct operational responsibilities of ICT and EPT. Similarly, the positions of WD (Weapon Director) and ST (Sensor Technician) or Ground Liaison and Air Support do not align with the defined responsibilities to the AST as needed in the context of sensor operations.
