Airmen from the 51st Civil Engineer Squadron stand on a folded fiberglass mat as it is moved into place by a 10,000-pound forklift on a simulated runway at Jungwon Air Base, Republic of Korea, Aug. 19. The 30-foot long, 54-foot wide mats are used to quickly repair runway damage, and can be connected to cover a large area. The mats are being moved as part of a joint combined rapid runway repair training exercise with Airmen from the Republic of Korea Air Force's 19th Tactical Fighter Wing and 91st Air Civil Engineer Group. The 51st CES is assigned to Osan Air Base, Republic of Korea. (U.S. Air Force photo/Senior Airmen Stephenie Wade)
