U.S. Marine Corps Pfc. Magaly Olguin, a desk clear, and a native from Laredo, Texas, with General Facilities (GF) Headquarters and Support Battalion, prepares to repair a threshold light on the airfield during on-the-job training with Navy Seabees, on Marine Corps Air Station Futenma, Okinawa, Japan, Dec. 3, 2020. When a service ticket is issued, GF Marines shadow Seabees to learn their side of the job. Seabees are trained to build and maintain permanent structures while Marines are trained in expedient construction and maintenance. The training is hands-on, teaching Marines how to build, plumb and power structures to code for long term use. (U.S. Marine Corps photo by Cpl. Karis Mattingly)
