The 200th Military Police Command is the senior law enforcement unit within the U.S. Army Reserve. The subordinate elements of the 200th MP Command are primarily military police units, but the command also includes criminal investigation detachments, chaplains, historians, and public affairs detachments. Units are dispersed across the continental United States with major subordinate units located in California, Michigan, New York, Tennessee, and Indiana. The formation of this command is a departure from the legacy structure of a strategic force in the Army Reserve with assigned chains of command based mostly on geography. The purpose of this command is to train, command, and deploy units primarily by their functional capabilities.

Fort George G. Meade is a United States Army installation located in Maryland, that includes the Defense Information School, the Defense Media Activity, the United States Army Field Band, and the headquarters of United States Cyber Command, the National Security Agency, the Defense Courier Service, Defense Information Systems Agency headquarters, and the U.S. Navy's Cryptologic Warfare Group Six. It is named for George G. Meade, a Union general from the U.S. Civil War, who served as commander of the Army of the Potomac. The fort's smaller census-designated place includes support facilities such as schools, housing, and the offices of the Military Intelligence Civilian Excepted Career Program (MICECP).
