Incredible footage of crewmen from the U.S. Coast Guard Cutter USS Douglas Munro jumping onto the top of a self-propelled semi-submersible narco vessel in choppy water in the Pacific Ocean. The coast guard vessel was patrolling off the coast of Colombia on June 18, 2019. These semi-subs float partially underwater to avoid detection and are hard to find and hard to capture. The sub's crew were arrested and its contents seized. This rare, successful interdiction was part of a three Coast Guard vessel operation patrolling international waters off the coasts of Mexico, and Central and South America watching for contraband. They delivered the fruits of their labour —from 14 separate stops of narco-vessels — worth an estimated US$569 million at Naval Air Station North Island in San Diego on July 11, 2019. The guards were greeted and congratulated by U.S. Vice President Mike Pence after arriving back in port.
