Several media outlets are calling MCAS Miramar-based Marine Corps Cpl. Jordan L. Spears, 21, the first casualty of the U.S. military's campaign against ISIS (also called ISIL and the Islamic State). Spears was lost at sea when he bailed out of a MV-22B Osprey after the aircraft appeared to lose power after taking off from the USS Makin Island in the North Arabian Sea.
