The 100th Missile Defense Brigade (Ground-based Midcourse Defense) is a multi-component brigade consisting of active-component Army and Army National Guard Soldiers in Colorado, California and Alaska who are tasked with the mission of defending the homeland from limited intercontinental ballistic missile attacks.
Utilizing a worldwide array of space, sea and land-based sensors, these missile defense crews are able to detect missile launches, track their trajectories and, if determined to be a threat to the homeland, launch ground-based interceptors located at Fort Greely, Alaska, and Vandenberg Air Force Base, California, to neutralize that threat.
Missile defense crews from the Headquarters and Headquarters Battery, 100th Missile Defense Brigade (GMD) operate the fire control node, the Missile Defense Element, at Schriever Air Base, Colorado, monitoring the skies 24/7/365. Alaska Army National Guard missile defense crews from HHB, 49th Missile Defense Battalion (GMD) perform their operational mission at the Fire Direction Center at Fort Greely while Alpha Company, 49th Military Police provide security for Fort Greely’s Missile Defense Complex. Detachment 1, 100th Missile Defense Brigade, is part of the California Army National Guard and located at Vandenberg Air Force Base. This small detachment is responsible for monitoring the launch facilities located there.
