United States Army Space and Missile Defense Command

The United States Army Space and Missile Defense Command (USASMDC) is the Army Service Component Command (ASCC) for United States Strategic Command and United States Space Command. It was established in 1985 as the Army Strategic Defense Command, responsible for ballistic missile defense. In 1992, it merged with Army Space Command to become Army Space and Strategic Defense Command. In 1997, it became an Army Major Command and was redesignated Army Space and Missile Defense Command.

Army Space and Missile Defense Command is responsible for developing and providing the Army with space, missile defense and high altitude capabilities. It consists of two operational elements: the 100th Missile Defense Brigade and the 1st Space Brigade. The current Army Space and Missile Defense Command commander is Lieutenant General Sean Gainey with Command Sergeant Major John W. Foley serving as the senior enlisted advisor. The commander of Army Space and Missile Defense Command also serves as the commander of United States Space Command's Joint Functional Component Command for Integrated Missile Defense.

Following the Space Force's establishment, the Army's continued involvement with space has become controversial, with multiple proposals and reports advocating for the Space Force to absorb the Army's remaining space forces, as it did with the Navy's space forces, or even Space and Missile Defense Command as a whole. The Space Force has absorbed the Army's satellite communications mission and the Joint Tactical Ground Stations, while the Army maintains the 100th Missile Defense Brigade and a downsized 1st Space Brigade. The Army is attempting to redefine its role in space operations, focused on integrating and interdicting space capabilities for land forces.
