Lance Cpl. Shawn Sullens, an engineer with Combat Logistics Battalion 3, slides part of a wall into position during a building project at Marine Corps Training Area Bellows, March 21, 2014. The project’s purpose is to modify shipping container units into a low quality home with a full roof, door and windows, to give the simulated appearance of a real home within the training area. The units placed in remote areas between military operations on urban terrain facilities would provide Marines a better training experience when patrolling through the different sites.
