Providing reliable, quality equipment to deploying Airmen
Roger Jordan, a contractor from Tyndall Air Force Base, Fla., tests the drinking tube of an M-50 Joint Service General Purpose Mask for blockage on Barksdale Air Force Base, La., July 21, 2014. In order to test the drinking tube for leakage, the tube is inserted into a Joint Service Mask adapter kit, which transfers air into the tube and tests the air pressure inside. Little or no air pressure means there is leakage in the drinking tube and that it needs replacing. (U.S. Air Force photo/Senior Airman Benjamin Gonsier)
