JOINT BASE LANGLEY-EUSTIS, Va. – U.S. Air Force Senior Airman Miguel Holloway, 633d Civil Engineer Squadron firefighter, prepares to perform hydraulic ventilation inside the burn building during a rapid intervention team work exercise at Joint Base Langley-Eustis, Virginia, Nov. 17, 2022. As large amounts of air enter the room, knowing when to divert from ventilation to douse smoldering embers and mitigate any flare-ups is crucial.
