US Army South (USARSO)

U.S. Army South (USARSO) traces its origins to the Panama Canal Department, established in 1917 to protect the strategic waterway. During World War II, the command’s role expanded to defending the region and supporting anti-submarine operations. In 1986, it was redesignated as U.S. Army South and relocated to Fort Sam Houston, Texas, in 2008. Today, USARSO serves as the Army Service Component Command of U.S. Southern Command, responsible for military operations and security cooperation throughout Central and South America and the Caribbean.
