JCAD testing
Airman 1st Class Charles Beutler, 305th Aerial Port Squadron, uses the Joint Chemical Agent Detector to check for cargo contamination during simulated JCAD operational tests conducted here Aug. 27. The tests will help the Air Force decide if the JCAD, used to detect nerve, blood and blister agents, will be used by personnel in the future. (U.S. Air Force photo/Airman 1st Class Rebekah Phy)
