Contractors wire rebar together to support the weight of the poles for a new 379th Expeditionary Security Forces Squadron sunshade, Jan. 12 at Al Udeid Air Base, Qatar. The rebar supports the foundation for the poles, ensuring they will not sink into the ground once the sunshade is up. Blocks will also be positioned on top of the rebar and filled with cement to help secure the sunshade’s foundation. (U.S. Air Force photo by Tech. Sgt. Terrica Y. Jones/Released)
