The #FLEX2026 exercise in Key West, Florida, is advancing the objectives of the newly established SOUTHCOM Autonomous Warfare Command (SAWC) to embrace cost-effective autonomous, semi-autonomous, and unmanned platforms and systems to counter threats and challenges in the region.

We applaud our security partners in Saint Vincent and the Grenadines for their recent seizure of more than 435 kg of cocaine and arrest of two suspects charged with illegally entering the country’s sovereign territory aboard a yacht while in possession of the seized illegal narcotics. Under the Caribbean Basin Security Initiative, the U.S. has worked closely with Caribbean partners since 2010 to develop Caribbean countries’ capabilities to disrupt illicit trafficking and transnational crime, advancing Caribbean and U.S. national security. U.S. Southern Command is also working with other partner nations in the region who have joined the Americas Counter Cartel Coalition to expand cooperation focused on countering narco-terrorism, transnational narcotics trafficking, and other shared threats to the Western Hemisphere. @DeptofWar
