The Army is in the midst of aligning specific units with geographical regions (regionally aligned forces, or RAF) to strengthen cultural awareness and language skills, facilitate force management, and improve security cooperation (SC) efforts around the world. Given the substantial role that the Army plays in U.S. SC, it is important to understand the RAF's value in making SC more effective. To address this, the Army asked the RAND Arroyo Center to assess the initial use of a RAF in Africa, focusing on SC, as part of a project titled "Assessing the Value of Regionally Aligned Forces in Army Security Cooperation." This project assessed the RAF's effectiveness in Africa for improving SC planning and execution. This report provides highlights from recent Arroyo Center research on the value of Army RAF to U.S. SC activities, particularly those conducted in Africa. This research was sponsored by the U.S. Army Deputy Chief of Staff, G-8, and conducted within the RAND Arroyo Centers Strategy, Doctrine, and Resources Program. RAND Arroyo Center, part of the RAND Corporation, is a federally funded research and development center sponsored by the United States Army.
