Fitting faces for fighting capabilities
U.S. Air Force 2nd Lt. Marina Cumming, 9th Operations Support Squadron intelligence officer, looks at the ceiling during a gas mask fit test while Senior Airman Lamont Davis, 9th Aerospace Medicine Squadron bioenvironmental technician, checks to see if Cumming has a proper seal at the bioenvironmental office at Beale Air Force Base, Calif., March 7, 2018. Looking up and down and side to side are some tasks Airman must perform to successfully pass the fit test. (U.S. Air Force photo by Senior Airman Colville McFee)
