The BGM-109G was developed as a counter to the mobile medium- and intermediate- range ballistic nuclear missiles deployed by the Soviet Union in Eastern Bloc European countries. The GLCM and the U.S. Army's Pershing II were the incentives that fostered Soviet willingness to sign the Intermediate-Range Nuclear Forces Treaty (INF treaty), and thus eventually reduced both the number and the threat of nuclear warheads in Europe. GLCM is also a generic term for any ground-launched cruise missile. Since the US deployed only one modern cruise missile in the tactical role, the GLCM name stuck. The GLCM was built by General Dynamics.
