Theater Security Cooperation
The stability and security of the United States, and partner nations hinges upon our ability to work together to confront and defeat common security challenges. Focused regional security cooperation is key to building interoperability and other capabilities required to confront challenges before they mature into direct threats. Coalitions and regional partnerships comprised of capable and willing nations build mutual security, deter aggression and extremism, and provide the underlying conditions for success if military action is required.
The role of U.S. Marine Corps Forces South is to satisfy U.S. Southern Command's Theater Security Cooperation (TSC) requirement through the efficient employment of the U.S. Marine Corps Forces. U.S. Marine Corps Forces South supports 28 partner nations targeting 16 Partner Nation Naval Infantries or Maritime Security Forces in Latin America and the Caribbean, training more than 55,000 Marines.
