What is MARS?

The Military Affiliate Radio System (MARS) is a Department of Defense sponsored program, established as separately managed and operated programs by the Army, Navy-Marine Corps and Air Force. MARS members are volunteer licensed amateur radio operators who are interested in providing auxiliary or emergency communications to local, national and international emergency and safety organizations, as an adjunct to normal communications.

The primary concept of MARS is to meet the requirements of training for any communications emergency. To this end, organization, methods and facilities must be adequate to meet any emergency requirements and must be flexible in order to provide for rapid expansion. Normal methods must be such that only minor changes will be required when shifting to an emergency status.

The Mission of the MARS system is to:

provide auxiliary communications for military, federal and local disaster management officials during periods of emergency or while conducting drills in emergency procedures.
assist in effecting normal communications under emergency conditions.
create interest and furnish a means of training members in military communications procedures and provide a potential reserve of trained communications personnel.
handle morale and quasi-official message and voice communications traffic for members of the Armed Forces and authorized U.S. Government civilian personnel stationed throughout the world.
provide, during daily routine operations, a method of exchanging MARSGRAMS and two-way telephone contacts between service personnel and their families back home. In carrying out this assignment, MARS operates a 24-hour message relay system and maintains a series of electronic mailboxes throughout the world.
conduct daily traffic and training nets, drills and critiques to train operators and test the systems readiness to handle demands during an emergency.
