U.S. Southern Command

U.S. Southern Command. It is one of the eleven unified combatant commands of the United States Department of Defense. Originally established as the Caribbean Command in 1947, it was re-designated in 1963 to focus on the Latin American region, excluding Mexico. The command is headquartered at Doral, Florida, in facilities on the grounds of the former Homestead Air Reserve Base.

History

The command's origins trace to the post-World War II reorganization of the U.S. Armed Forces, with the Caribbean Command created to oversee defense interests in the region. Its establishment was influenced by strategic concerns during the Cold War, particularly the spread of communism following the Cuban Revolution and the rise of Fidel Castro. The command was heavily involved in contingency planning during events like the Cuban Missile Crisis and supported counter-insurgency efforts against groups such as the Farabundo Martí National Liberation Front in El Salvador. Following the Panama Canal Treaties and the United States invasion of Panama, which ousted Manuel Noriega, its headquarters moved from Panama to Miami in 1997.

Mission and area of responsibility

Its mission is to conduct military operations and promote security cooperation to defend the United States and its interests in its assigned area of responsibility. This area encompasses 31 countries and 15 areas of special sovereignty in Central America, South America, and the Caribbean Sea, representing over 16 million square miles. The command focuses on transnational threats, including counter-narcotics operations, counter-terrorism, and building the capacity of partner nations' armed forces. It does not include responsibility for Mexico, The Bahamas, or the U.S. territories in the Caribbean, which fall under United States Northern Command.

Organization

The command is composed of several service component commands and subordinate units. These include United States Army South at Fort Sam Houston, United States Naval Forces Southern Command at Naval Station Mayport, United States Air Forces Southern at Davis–Monthan Air Force Base, United States Marine Corps Forces South at Doral, Florida, and United States Special Operations Command South. The command also works closely with other federal agencies such as the United States Coast Guard, the Drug Enforcement Administration, and the United States Agency for International Development through integrated planning cells.

Operations and activities

Key operations have included Operation Just Cause in Panama, Operation Uphold Democracy in Haiti, and numerous humanitarian missions like Operation Unified Response after the 2010 Haiti earthquake. The command routinely conducts major exercises such as PANAMAX, focused on Panama Canal security, and Tradewinds, held with Caribbean partners. It leads extensive security cooperation programs, providing training through units like the United States Army School of the Americas and supporting maritime interdiction via partnerships with countries like Colombia and Peru. Its Joint Interagency Task Force South, based at Naval Air Station Key West, is a key hub for multinational counter-narcotics efforts in the Caribbean and Eastern Pacific.

Commanders

Commanders have historically been drawn from the United States Army, the United States Navy, and the United States Marine Corps. Notable past commanders include George A. Joulwan, who later led United States European Command, and James T. Hill, who oversaw the command's transition post-September 11 attacks. More recent commanders include John F. Kelly, who later served as White House Chief of Staff, and Kurt W. Tidd, a former United States Navy admiral. The current commander, since 2021, is United States Army General Laura J. Richardson, the first woman to lead the command.

Relationship with partner nations

The command maintains strong bilateral and multilateral relationships through its Security Cooperation Offices embedded in U.S. embassies. It works closely with regional institutions like the Organization of American States and the Inter-American Defense Board. Key partnerships include long-standing alliances with Colombia in combating groups like the Revolutionary Armed Forces of Colombia, and with Brazil through joint naval exercises. The command also engages with Caribbean nations via the Caribbean Community and provides disaster response coordination through the Humanitarian Assistance Program. These relationships are central to its strategy of building partner capacity to address shared security challenges.
