Military Auxiliary Radio System

M.A.R.S. / MARS / Mars Radio

MARS is a civilian radio program consisting primarily of licensed amateur radio operators who are interested in assisting the military with communications on a local, national, and international basis as an adjunct to normal communications. The MARS programs also include active duty, reserve, and National Guard units; Navy, Marine Corps, and National Oceanic and Atmospheric Administration ships, and Coast Guard cutters and shore stations.

Military Auxiliary Radio System provides Department of Defense sponsored emergency communications on a local, national, and international basis. MARS also provides auxiliary communications for military entities only. One major mission that MARS has had for many years is to handle morale, welfare, and official record and voice communications traffic for Armed Forces and authorized U.S. Government civilian personnel stationed throughout the world.

Every year, MARS conducts an appropriate military and amateur radio cross-band exercise as an integral part of the annual Armed Forces Day. They provide a reserve of personnel trained in military radio communications, techniques, and procedures as well as to initiate efforts to improve radio-operating techniques. MARS members test state-of-the-art technology through experimentation and testing.

Morale and welfare messages are no longer the largest activity in MARS due to the increased use of the Internet and e-mail by deployed military personnel. MARS had an increased role in providing interoperability communications between Army National Guard and Air National Guard forces and civilian state agencies. However, this service providing interoperability communications was terminated as of May 2015.

MARS also supports government agencies such as the Federal Emergency Management Agency, and participates in programs such as the Department of Homeland Security Office of Emergency Communications SHAred RESources (SHARES).
