FIRST ON FOX: The U.S. Air and Marine Operations (AMO) deployed a Black Hawk helicopter to intercept a boat suspected of smuggling drugs off the coast of Puerto Rico earlier this month. On May 14, AMO detected a 25-foot blue vessel carrying three people and visible packages. After surveilling its activity, the San Juan Marine Unit deployed a pair of law-enforcement boats, flanked by the Black Hawk, according to U.S. Customs and Border Protection (CBP). The agency seized three Dominican Republic nationals along with five bales containing 391 pounds of cocaine. The helicopter-assisted takedown is just the most recent display of American military might that has been targeting narcotrafficking operations south of the U.S. border.
