U.S. Army South (ARSOUTH) conducts and supports multinational operations and security cooperation in the U.S. Southern Command area of responsibility in order to counter transnational threats and strengthen regional security in defense of the homeland.


A flexible, agile and responsive Army Service Component Command capable of simultaneously conducting contingency operations and Theater Security Cooperation engagements for U.S. Southern Command and Department of the Army.  

As the combatant command (COCOM) support agent, U.S. Army South provides an, appropriate, fiscally responsive and maximum level of support based upon available resources.  

US Army South is responsive to the COCOM as we work to become the “partner of choice” for Regional Armies.  

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
