Ground Mobile Forces

Ground Mobile Forces (GMF) is the term given to the tactical SATCOM portion of the Joint Service program called TRI-TAC developed in the mid-1970s. The Tri-Service Tactical signal system is a tactical command, control, and communications program. It is a joint service effort to develop and field advanced tactical and multichannel switched communications equipment. The program was conceived to achieve interoperability between service tactical communications systems, establish interoperability with strategic communications systems, take advantage of advances in technology, and eliminate duplication in service acquisitions.
