YOKOTA AIR BASE, Japan -- Airmen of the 374th Civil Engineer Squadron finish placing a fiberglass mat during airfield damage repair training on the flightline here. During the training, the 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.
