Maj. Timothy Birt and Capt. Greg Sewell, C-17 Globemaster III pilots from the 15th Airlift Squadron, 437th Airlift Wing, Joint Base Charleston, S.C., conduct pre-flight checks on the ramp at Joint Base Elmendorf-Richardson, Alaska prior to takeoff July 12, 2017 to participate in and provide airlift support for Exercise Talisman Saber 2017. The purpose of TS17 is to improve U.S.-Australian combat readiness, increase interoperability, maximize combined training opportunities and conduct maritime prepositioning and logistics operations in the Pacific. TS17 also demonstrates U.S. commitment to its key ally and the overarching security framework in the Indo Asian Pacific region. (U.S. Air Force photo/Tech. Sgt. Gregory Brook)
