Final answer:
Ground Theater Air Control (GTACS) can be deployed in either the Control Reporting Center or Control Reporting Element configurations.
Step-by-step explanation:
The correct answer is Ground Theater Air Control (GTACS). GTACS can be deployed in both the Control Reporting Center (CRC) and Control Reporting Element (CRE) configurations.
The Global Broadcast Service (GBS) is a satellite-based communication system used for worldwide information and data dissemination. It is not specifically designed for deployment in CRC or CRE configurations.
The Distributed Common Ground Station (DCGS) is a network of intelligence, surveillance, and reconnaissance systems used for gathering and processing information. It is not directly related to the CRC or CRE configurations.
The Base Control System-Fixed (BCS-F) is a command and control system used for managing and controlling air defense operations. It is not applicable to CRC or CRE configurations.
