Lance Cpl. Marco S. Buehler, a scout sniper from Battalion Landing Team 2/6, 26th Marine Expeditionary Unit, fires his MK-11 sniper rifle from the window of a CH-46E Sea Knight helicopter while flying over the Gulf of Aden Sept. 27, 2009. Buehler and his fellow snipers practiced firing various weapons at floating targets while aboard moving helicopters during the training exercise. The 26th MEU and Iwo Jima Strike Group are currently deployed in the Central Command area of responsibility. (Official USMC photo by Cpl. Aaron J. Rock) (Released)
