U.S. Army Lt. Col. William Bosworth, a veterinarian and commander of the 719th Medical Detachment Veterinary Services, Ft. Sheridan, Illinois, injects deworming medication into a bull during a Medical Readiness Training Exercise (MEDRETE) in Cerro Plata, Veraguas, Panama, on April 15, 2013. The MEDRETE is part of U.S. Army South's Beyond the Horizon exercise that is taking place in Panama. 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, underprivileged 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.
