U.S. Marines with General Facilities (GF) and Navy Construction Electrician 2nd Class Ira Mozee, a native of Saint Lucie, Florida, repair threshold lights on the airfield during on-the-job training with 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)
