A Koku-Jieitai officer hammers sheet metal on a metal forming stake during a Basic Maintenance Officer Tour at Yokota Air Base, Japan, May 31, 2018. The tour not only gave officers a hands-on experience but also offered a chance to bolster relationships between the 374th Maintenance Group and their Japanese counterparts.
