The United States Marine Corps (USMC) has developed the Security Cooperation Marine Air Ground Task Force (SC MAGTF) concept of force employment that will enable partner nations to foster stability in their respective regions. The USMC is prepared to be the solitary architect of this force; however the proposed employment of the SC MAGTF is a bold unilateral endeavor. A regionally focused security cooperation force is the ideal employment construct for the Department of Defense (DOD) but it must sufficiently integrate United States government agency capabilities and incorporate joint force multipliers. This thesis analyzes the potential requirement for a specialized DOD security cooperation force and determines whether a joint and interagency venture will further enhance and legitimize the US Marine Corps' current employment concept. The aim of this research is to develop a significant contribution to the format of the SC MAGTF in order to ensure its success and permanent establishment within the regional civil-military arsenal.
