The United States Southern Command (USSOUTHCOM) is the unified command responsible for all U.S. military activities on the land mass of Latin America south of Mexico; the waters adjacent to Central and South America; the Caribbean Sea, with its 13 island nations, and European and U.S. territories; the Gulf of Mexico; and a portion of the Atlantic Ocean. Since 26 September 1997, the command headquarters has been located at Miami, Florida. It is one of five geographically unified commands under the U.S. Department of Defense.* Southern Command’s area of responsibility encompasses 32 countries (19 in Central and South America and 13 in the Caribbean) and covers about 14.5 million square miles (23.2 million square kilometers). The region represents about one-sixth of the landmass of the world assigned to regional unified commands.

The Southern Command, which has about 3,000 permanently assigned military and civilian personnel, has the following components: United States Army South (USARSO) at Fort Buchanan, Puerto Rico; Commander U.S. Naval Forces Southern Command (COMNAVSO), at Naval Station Roosevelt Roads, Puerto Rico; U.S. Southern Air Forces (12th Air Force at Davis-Monthan Air Force Base in Arizona); U.S. Marine Forces South (MARFORSO) in Miami, Florida; and Special Operations Command at Roosevelt Roads, Puerto Rico.
