The Greenland Base Command (GBC) refers to the United States Army’s administrative jurisdiction over military installations in Greenland. Established in 1951, it oversees Thule Air Base, the primary U.S. strategic arctic installation, and Camp Century, a decommissioned research facility. The GBC supports various missions, including missile defense, early warning of incoming ballistic missiles, and scientific research collaborations with Danish scientists. The Command is part of the North American Aerospace Defense Command (NORAD) and the United States Northern Command (USNORTHCOM), ensuring national security in the Arctic region.
