PACIFIC OCEAN (May 7, 2017) - The guided-missile destroyer USS Preble (DDG 88) fires at an unmanned aerial vehicle during a Group Sail training unit exercise (GRUSL) with the Theodore Roosevelt Carrier Strike Group (TRCSG). GRUSL is the first step in Preble's integrated training phase and aims to enhance mission-readiness and warfighting capabilities between the ships, air wing and the staffs of the TRCSG through simulated real-world scenarios.
