Colombian Marines are trained in a variety of amphibious skills and utilize many tools to allow them to conduct amphibious operations. UNITAS, hosted by Colombia this year, is the world’s longest-running annual multinational maritime exercise that focuses on enhancing interoperability among multiple nations and joint forces during littoral and amphibious operations in order to build on existing regional partnerships and create new enduring relationships that promote peace, stability, and prosperity in the U.S. Southern Command’s area of responsibility.
