Southern Command (United States Southern Command) is a unified combatant command of the United States Department of Defense responsible for U.S. military operations, security cooperation, and contingency planning in Central America, South America, and the Caribbean. Established during the Cold War, the command has engaged with regional partners such as Colombia, Brazil, Mexico, Panama, and Argentina through counter-narcotics, disaster response, and humanitarian assistance. Headquartered in Miami, Florida, the command coordinates with agencies including the United States Agency for International Development, Department of State (United States), and the United States Southern Command Joint Interagency Task Force South.

History

The command traces lineage to earlier entities like United States Caribbean Command and United States Army Southern Command formed after World War II, adapting through events such as the Cuban Revolution, the Bay of Pigs Invasion, and the Cuban Missile Crisis. During the 1970s and 1980s, engagements with countries including El Salvador, Guatemala, and Nicaragua reflected U.S. policy amid the Cold War. Post-Cold War operations shifted toward counternarcotics cooperation with partners like Colombia during Plan Colombia and humanitarian missions responding to disasters such as Hurricane Mitch and the 2010 Haiti earthquake. In the 21st century, cooperation expanded with initiatives involving Brazilian Armed Forces, Peru, Chile, and multilateral forums including the Organization of American States and the Inter-American Defense Board.

The command integrates joint components from the United States Army, United States Navy, United States Air Force, United States Marine Corps, and United States Space Force elements tailored to the region. Subordinate commands and centers include the U.S. Southern Command Joint Task Force Bravo at Soto Cano Air Base, the Joint Interagency Task Force South operating from Key West, Florida, and coordination with the U.S. Naval Forces Southern Command. Staff directorates align with the Joint Staff model, linking to functional components such as logistics cooperation with U.S. Transportation Command and intelligence sharing with the Defense Intelligence Agency and National Geospatial-Intelligence Agency. The command leverages liaison relationships with the U.S. Embassy network across capitals like Bogotá, Lima, Georgetown, San José, and Brasília.
