The U.S. Department of Homeland Security has released footage from Tuesday showing the interdiction of a cartel narco-trafficking vessel carrying 20,000 pounds of cocaine in the Eastern Pacific. The operation was conducted by an MH-65E Dolphin helicopter from the U.S. Coast Guard’s Helicopter Interdiction Tactical Squadron (HITRON), deployed with the Legend-class cutter USCGC Munro (WMSL-755).

In the video, a sniper aboard the MH-65E uses a Barrett M82 .50 BMG anti-materiel rifle to disable the fast boat’s engine, allowing a Coast Guard Special Purpose Craft launched from the Munro to board and seize the vessel as part of Operation Pacific Viper.
