U.S. Air Force members from Task Force Red Horse erect a new-form wall system for a clinic in Escobal, Panama, during the Beyond the Horizon exercise on April 18, 2013. Beyond the Horizon is a U.S. Southern Command-sponsored, U.S. Army South-planned and led annual humanitarian and civic assistance exercise that provides construction and medical assistance to partner nations throughout Central and South America and the Caribbean. The exercise generally takes place in rural areas and is a major component of the U.S. military's regional engagement efforts and it affords a unique opportunity to train U.S. service members alongside partner nation personnel, while providing needed services to communities throughout the region.
