Barrier signs
Airman 1st Class James Ori, 22nd Civil Engineer Squadron structures apprentice, and Marshall Townsend, 22nd CES maintenance mechanic, replace signs on serpentine barriers at the main gate, June 21, 2016, at McConnell Air Force Base, Kan. Having barriers at the gate helps increase safety and security on the base. (U.S. Air Force photo/Airman Erin McClellan)
