Adja, a German Shepard military working dog assigned to the 380th Expeditionary Security Forces Squadron, passes through a training tube in the 380th ESFS obedience yard, October 20, 2022 at Al Dhafra Air Base, United Arab Emirates. By practicing in the obedience yard, handlers can ensure their MWD is familiar with different obstacles so they are not impeded by new terrain on the job. (U.S. Air Force photo by Tech. Sgt.
