The 100th Missile Defense Brigade operates the Ground-based Midcourse Defense (GMD) System defending America and its territories. Several factors make the 100th Missile Defense Brigade unique- the brigade is the ONLY unit in the world that can destroy incoming intercontinental ballistic missiles (ICBMs) carrying nuclear warheads.

Unlike most National Guard units, this Colorado unit is operating right now, 24/7/365, ready to intercept ICBMs. Since the 100th is actively defending our nation right now, all of it’s nearly 100 Soldiers are getting full time benefits, just like the active Army.

While we do have about a dozen active Army Soldiers, the majority of our nearly 100 Soldiers are full-time Colorado Army National Guard members. Full-time National Guard Soldiers receive the same benefits as active-duty soldiers (Tricare, housing allowance, etc), but the difference between active duty and full-time National Guard is National Guard Soldiers are eligible for state tuition assistance and do not need to move every 2-3 years like active duty Soldiers.

The Brigade Headquarters is located in Colorado Springs, Colo. For more information contact the unit at 720-250-3702.
