U.S. Air Force 18th Civil Engineer Squadron and Japan Air Self-Defense Force Southwestern Civil Engineering Group service members conclude a rapid airfield damage repair exercise Aug. 30, 2019, at Naha Air Base, Japan. The bilateral training event, which occurs twice a year, enhances the partnership between the two allies so they may more efficiently respond to events and contingencies that may cause damage to military airfields.
