U.S. Marine Sgt. Jesse Kimble observes his target during a deck shoot aboard the USS Essex (LHD 2) in the South China Sea, June 12, 2015. Kimble is a member of the 15th Marine Expeditionary Unit’s Maritime Raid Force. These Marines practice several types of shooting, such as shooting on the move, to imitate the type of engagements they would have to use in a real-life scenario. (U.S. Marine Corps photo by Cpl.
