(L to R) Capt. Cyrus Macapagal, Col. Kevin Krebs and Master Sgt. Jim Biere stack over 500 sandbags in the parking lot of the 452nd Air Mobility Wing headquarters building. Midway into the process, other troops from around base joined in to help. They were participating in a hardening demo to increase awareness for the Operational Readiness Inspection in February that simulated building a four-foot high wall of sand bags around a designated structure. Select participants will be chosen to take part in five hardening demonstrations that will be graded by Air Mobility Command inspectors during the actual ORI. (U.S. Air Force photo by Amy Abbott)
