Senior Airman Patrick Bass, 374th Maintenance Squadron

Senior Airman Patrick Bass, 374th Maintenance Squadron engine manager, calls the final chock hold competition as a referee during the annual 374th Maintenance Group Wrenchbender rodeo at Yokota Air Base, Japan, March 31, 2017. The chock hold competition challenged Airmen to endure holding chocks up longer than opposing teams. A chock is a wedge placed against a wheel to prevent an aircraft from movement.
