Misawa CES personnel badn together for airfield construction
Youichi Yamada, a Japanese contractor, uses a trowel to put finishing touches on newly laid concrete at Misawa Air Base, Japan, May 23, 2017. After concrete is laid down, it is smoothed out with a trowel, which pushes heavier rocks down and provides a clean, smooth surface. (U.S. Air Force photo by Airman 1st Class Sadie Colbert)
