MARS participates in exercises such as Grecian Firebolt to help support military communications. MARS members from all around the world played a role in Grecian Firebolt 2005 by sending exercise Essential Elements of Information (EEI) reports through the MARS radio network. The EEI's consisted of scenario disaster information. When the EEI's were received, they were sorted and sent to Army Military Intelligence centers. MARS played a large part in reporting up-to-date information on disasters and requesting military assistance using a dispersed and redundant radio network.
