Smoke flowed from the front door of the Hazmat Pharmacy Environmental building during a bomb exercise at Truax Field, Madison, Wis., Aug. 23, 2013. The EOD team added realism by filling that building up with smoke, giving the rescue teams a challenge when removing the victims. The exercise was part of a new Air Force Inspection System initiative. (Air National Guard photo by Senior Airman Andrea F. Liechti)
