U.S. Air Force Senior Airman Darian O’Banion, 386th Expeditionary Logistics Readiness Squadron vehicle and equipment maintenance journeyman, lines up a driveshaft for installation on a vehicle at Ali Al Salem Air Base, Kuwait, July 29, 2019. The driveshaft is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them.
