SOUTHWEST ASIA – Staff Sgt. James Michalisko, 386th Expeditionary Civil Engineer Squadron fire firefighter, dons his self-contained breathing apparatus in preparation to enter a smoking building during an exercise here August 7. Firefighters use protective gear to shield themselves from open flame and the temperature from the smoke. The fire fighters will also bring a tool such as an ax or a halogen bar if there’s a possibility of forcible entry. (U.S. Air Force photo/Staff Sgt. Alexandra M. Boutte)
