The first commanding officer of a Marine Reserve Osprey squadron, Lt. Col. David A. Weinstein, an Osprey pilot, addresses service members, family and friends after a change of command ceremony at Edwards Air Force Base near Lancaster, Calif., Jan. 12, 2013. Weinstein took command of Marine Medium Helicopter Squadron 764 (HMM-764) before the unit was re-designated to Marine Medium Tiltrotor Squadron (VMM-764). The Marine Forces Reserve's first tiltrotor squadron has to establish programs, obtain qualifications and pass inspections before it can receive its first aircraft, expected in November 2013. The unit is expected to be a fully operational tiltrotor squadron by mid-2014. (U.S. Marine Corps photo by Sgt. Ray Lewis/Released)
