Osan's Airfield Damage Repair team exercises with Republic of Korea Air Force
Senior Airman Christopher Davis records data from a dynamic cone pentrometer test at Jungwon Air Base, Republic of Korea, Aug 19. The reading tells if the crater is sufficiently filled and compacted to withstand aircraft landings. This process was 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. Airman Davis is assigned to the 51st Civil Engineer Squadron, Osan Air Base, Republic of Korea. (U.S. Air Force photo/Senior Airmen Stephenie Wade)
