Marines join Kadena Airmen for contingency exercise
U.S. Air Force Senior Airman Brandon Agustin, 18th Civil Engineer Squadron electrician, sets up a threshold for runway lights during a joint airfield damage and repair contingency exercise at Kadena Air Base, Japan Feb. 26, 2015. The lights marked boundaries of a minimum operating strip, which is the space leftover after an airstrip is damaged and repaired. (U.S. Air Force photo by Airman 1st Class John Linzmeier)
