Chinook Soldiers: maintaining warfighting capabilities
U.S. Army Sgt. Benjamin Stocker, Colorado National Guard CH-47 flight engineer and mechanic, puts a washer into place Feb. 19, 2016, at the Army Aviation Support Facility on Buckley Air Force Base, Colo. As a part of installing a new droop stop spring, the washer kept the helicopter blades from falling too low during flights. (U.S. Air Force photo by Airman 1st Class Gabrielle Spradling/Released)
