PACIFIC OCEAN — Marines load an RQ-21A Blackjack onto the launcher on the flight deck of USS San Diego (LPD-22) during Composite Training Unit Exercise, May 2, 2017. The Marines refined their launch and recovery procedures of the RQ-21A Blackjack during COMPTUEX in order to provide reconnaissance for the planning and execution of future missions. Through a high degree of unit training, the 15th MEU forms a flexible sea-based Marine Air-Ground Task Force capable of mobilizing personnel and equipment to any corner of the globe.
