Building the foundation for autonomous warfare. During an operational visit to Naval Station Guantanamo Bay, #SOUTHCOM Commander Gen. Francis L. Donovan observed unmanned systems deployed in support of Joint Task Force Western Hemisphere missions. Their deployment also marks the first step toward developing a SOUTHCOM Autonomous Warfare Command (SAWC) training and mission-support site at NSGB, where teams can train and integrate autonomous capabilities, support operational requirements, and apply operational lessons to training and capability development. The SAWC integrates people, autonomous and unmanned systems, data, communications, and other capabilities around supported-command requirements to create decision and operational advantage. #JTFWHEM #UnmannedSystems #DroneWarfare #DroneDominance #AutonomousSystems @DeptofWar @secwar

Into the jungle. Soldiers with the 1-505th Parachute Infantry Regiment, 82nd Airborne Division, conduct the final assault of exercise Southern Vanguard 2026 in Sauce, Peru, Sept. 17, 2026.

The A3C is resolute in defeating narco-terrorist networks in our hemisphere. @DeptofWar

📦🇺🇸🇨🇷 Un avión de transporte militar C-17 de la Fuerza Aérea de Estados Unidos partió de Costa Rica con 45 toneladas de cocaína destinada para destrucción, incautada por Costa Rica con apoyo de Estados Unidos y otros países socios del Escudo de las Américas y la Coalición de las Américas contra los Carteles. Esta operación representa hasta más de 1,25 mil millones de dólares que quedan fuera de las manos de las redes criminales. 🤝 Una nueva era de cooperación en seguridad da resultados contra los carteles y hace de nuestro hemisferio un lugar más seguro. @DEAHQ @DeptofWar @Southcom #ÉxitosEnSeguridad
