===JTRS Ground Mobile Radios (GMR)===
JTRS GMR are a key enabler of the DoD and Army Transformation and will provide critical communications capabilities across the full spectrum of Joint operations. Through software reconfiguration, JTRS GMR can emulate current force radios and operate new [[Internet Protocol]] (IP)-based networking waveforms offering increased data throughput utilizing self-forming, self-healing, and managed communication networks. The GMR route and retransmit functionality links various waveforms in different frequency bands to form one internetwork. GMR can scale from one to four channels supporting multiple security levels and effectively use the frequency spectrum within the 2 megahertz to 2 gigahertz frequency range. The radios are Software Communications Architecture compliant with increased bandwidth through future waveforms and are interoperable with 4+ current force radio systems and the JTRS family of radios.

Now that the GMR contract has been completed, the Army plans to leverage knowledge gained from the GMR Program in the upcoming Mid-Tier Networking Vehicular Radio solicitation.<ref>[http://www.spacewar.com/reports/US_Army_Testing_Demonstrates_Readiness_of_Raytheon_MAINGATE_Radio_999.html "US Army Testing Demonstrates Readiness of Raytheon's MAINGATE Radio."] ''Space War'', January 13, 2012.</ref>
