Lt. Col. Todd Wydra, 515th Air Mobility Operations Group deputy commander, poses after completing the chock hold competition during the annual 374th Maintenance Group wrenchbender rodeo at Yokota Air Base, Japan, March 31, 2017. The chock hold competition challenged Airmen's endurance and the winners were determined by their ability to hold chocks up longer than their opponents. A chock is a wedge placed against a wheel to prevent an aircraft from movement. (U.S. Air Force photo by Yasuo Osakabe)
