Japan Air Self-Defense Force Master Sgt. Shimoji, from the Southwestern Civil Engineering Group, directs construction equipment operators during a rapid airfield damage repair exercise Aug. 30, 2019, at Naha Air Base, Japan. The exercise enabled U.S. and Japanese partners to reinforce and develop better training, tactics and procedures for bilateral large-scale responses for any event that causes damage to airfields.
