Why was the Missile Defense Complex placed at Ft. Greely?
From Ft. Greely, Alaska, the entire United States can be protected from long-range ballistic missiles. The area is remote, with a low population density. Plus, the infrastructure was already in place. Ft. Greely itself had been closed in the late 90s and all of the office buildings, maintenance shops and housing were empty. Finally, the geology of the area made it fairly easy to drill holes for silos.
