PACIFIC OCEAN (May 9, 2017) Lt. Lisa Malone, a warfare tactics instructor (WTI) assigned to the Naval Surface and Mine Warfighting Development Canter (SMWDC), provides tactical training to officers aboard the aircraft carrier USS Theodore Roosevelt (CVN 71) during a group sail training unit exercise. Group sail is the first step in the Theodore Roosevelt’s integrated training phase and aims to enhance mission-readiness and warfighting capabilities between the ships, air wings and the staffs through simulated real-world scenarios.
