Military Auxiliary Radio System
The Military Auxiliary Radio System ( MARS ; German " Military Auxiliary Radio System ") is a communication system of the United States Armed Forces , that of radio amateurs is operated. The radio stations of MARS do not belong to the amateur radio service ; they are operated on militarily coordinated frequencies outside the amateur bands and use their own call signs .
The organization was founded in 1925 as the Auxiliary Amateur Radio System of the United States Army Signal Corps . It was renamed the Military Amateur Radio System in 1948, the Military Affiliate Radio System in 1952, and the Military Auxiliary Radio System in 2009.
In the Korean War , Vietnam War and the Second Gulf War , private messages (Marsgrams) and radio communications (in connection with the public telephone network - Phone Patches ) were passed between soldiers overseas and their relatives in the USA via MARS . The connections were not protected against eavesdropping and could be received with standard shortwave receivers.
Since the Internet became available to soldiers, MARS has primarily been used to provide backup connections in emergencies.
