Which broadcast is eliminated when using the EPLRS communications configuration?

The correct choice focuses on the function of the Enhanced Position Location Reporting System (EPLRS) communications configuration, which is designed to support tactical battlespace awareness and improve situational awareness among units. When EPLRS is implemented, it streamlines the transmission of critical information by providing a more efficient communication channel for specific types of data.

The sensor broadcast network is eliminated because EPLRS incorporates a mechanism to gather and disseminate information predominantly related to position reporting and tactical data. While it maintains communication capabilities, the nature of EPLRS allows it to effectively replace the need for a separate network dedicated specifically to sensor data transmission, merging these functions into a more integrated and efficient system.

The other types of broadcasts remain relevant and continue to perform essential roles within the overall communication structure. The data broadcast network still functions to relay various operational data, the voice broadcast network enables critical verbal communications, and the maintenance broadcast network is necessary for equipment and system upkeep. The elimination of the sensor broadcast network in the context of EPLRS exemplifies the system's ability to streamline communication processes and enhance operational effectiveness.
