Welcome to the U.S. Army Military Affiliate Radio System (MARS) home page. We are headquartered at Fort Huachuca, Arizona, and assigned to the Headquarters, United States Army Network Enterprise Technology Command/9th Signal Command (Army) (NETCOM/9th SC(A)), which directly reports to the Department of the Army's Chief Information Officer/G-6.

MARS is a Department of Defense sponsored program, established as a separately managed and operated program by the Army, Navy, and Air Force. The program consists of licensed amateur radio operators who are interested in military communications on a local, national, and international basis as an adjunct to normal communications.

MARS has a long and proud history of providing world-wide auxiliary emergency communications during times of need. The combined three service MARS programs (Army, Air Force, and Navy-Marine Corps) volunteer force of over 5,000 dedicated and skilled amateur radio operators is the backbone of the MARS program. The benefit of MARS membership is enjoying an amateur radio hobby through the ever-expanding horizon of MARS. Our affiliate members' continued unselfish support of our mission keeps Army MARS Proud, Professional, and Ready.
