Breaking Defense:

The 100th Missile Defense Brigade is the only US military unit assigned to shoot down long-range ballistic missiles from North Korea. The brigade operates the Ground-Based Midcourse Defense (GBMD) system — an array of sensors supporting a fire-control system for missile-launched exoatmospheric kill vehicles to track, intercept, and destroy enemy warheads in their midcourse phase of flight, outside the earth’s atmosphere.

A component of US Army Space and Missile Defense Command, the 100th Missile Defense Brigade is based in Colorado Springs, Colo., and Fort Greely, Alaska. In the coming years, the GBMD mission will evolve as part of the Missile Defense Agency’s recently awarded and similarly named $3.3 billion Ground-based Midcourse Defense program where the current exoatmospheric interceptor will be replaced by the Next-Generation Interceptor.
