U.S. Army South's Mission, Vision, Enduring Priorities and Strategy



U.S. Army South (ARSOUTH) conducts security cooperation and responds to contingencies as part of a whole-of-government approach in conjunction with partner nation armies in the U.S. Southern Command Area of Responsibility as the Theater Army in order to strengthen regional security and counter transnational threats in defense of the homeland.



An Army Service Component Command comprised of "Trusted Professionals" working in concert with Partner Nation Armies ("By, With, Through") and other key stakeholders to conduct Theater Security Cooperation, Contingency Operations, Title 10 support and Combatant Command Support Agent requirements for U.S. Southern Command and Department of the Army.


     Command's Enduring Priorities

 Flexibility, agility and responsiveness are woven into the fabric of every ARSOUTH mission.  In order to meet the continued requirements for Theater Security Cooperation and Contingency Operations, ARSOUTH will work closely with the community of interest for the AOR, including joint, interagency, intergovernmental, and multilateral partner nations.  ARSOUTH uses the following enduring priorities to focus efforts to accomplish our mission throughout the AOR: 

1)      Contingency Readiness – ARSOUTH must sustain individual and collective training capability for immediate transition to contingency operations

2)      Primacy of Partnering – ARSOUTH will seek partnership in all regional initiatives

3)      Mission Resourcing – ARSOUTH is fiscally disciplined and a responsive steward of resources while meeting prioritized mission requirements

4)      Command Responsiveness – ARSOUTH is flexible, agile and responsive to subordinate elements, other components and USSOUTHCOM
