The primary role and responsibilities of a TERT team is to provide mission critical assistance for call-taking and dispatcher functions during and after a disaster incident.

The statement is correct because TERT (Telecommunicator Emergency Response Taskforce) teams are specifically organized to offer crucial support in the event of a disaster or emergency situation. Their primary mission revolves around ensuring that communication systems remain functional and that there are adequate resources to handle an influx of emergency calls. In times of crisis, standard operation procedures may be disrupted, leading to increased call volumes and potentially overwhelming local dispatchers.

TERT teams are trained to step in and assist with call-taking and dispatch functions to maintain public safety communications. Their deployment helps to ensure that essential services continue to operate efficiently, facilitating a coordinated response to emergencies. By providing backup support, TERT teams play a vital role in enhancing the overall efficacy of emergency response efforts during and following disaster scenarios.
