Master Sgt. Zach Dunkin, a 76th Aerial Port Squadron Reserve Citizen Airman, signals his fellow 76th APS member, Tech. Sgt. Tae Choe, to back up during the 25K Halvorsen driving and loading course on April 23, 2019, during the 2019 Port Dawg Challenge at Dobbins Air Reserve Base, Georgia. The team was graded on how quickly and safely they could operate a Halvorsen through an obstacle course. In deployment locations, the faster the aircraft is loaded the less time soldiers are exposed to enemy fire waiting for an airdrop. (U.S. Air Force photo/Senior Airman Noah J. Tancer)
