YOKOTA AIR BASE, Japan -- Staff Sgt. Orlando Crespo helps move a fiberglass mat during airfield damage repair training on the flightline here. During the training, 374th Civil Engineer Squadron Airmen simulated drilling holes into the runway to secure the mats. The mats provide a protective surface for aircraft landing in austere locations. The Airmen are trained to deploy into bare-base locations, assess airfield capabilities, prepare aircraft landing areas, clear obstacles, install emergency airfield lighting systems and repair airfield damage.
