Airman First Class Kile Larsen, 379th Expeditionary Civil Engineer Squadron firefighter, is processed through the decontamination line during a hazardous materials qualification exercise May 10, at Al Udeid Air Base, Qatar.

Larsen's home station is Joint Base Elmendorf-Richardson, Alaska, and his hometown is Emmett, Idaho (U.S. Air Force photo/Senior Airman Colin Cates
