Staff Sgt. Omari-Darnell Ferguson and Senior Airman Taylor Tschida, both 28th Security Forces Squadron alarm monitors, talk inside the gate shack at the Liberty Gate on Ellsworth Air Force Base, S.D., Dec. 4, 2018. Each person that comes through the gate gets checked for proper authorization, correct seatbelt wear and that their vehicle has registration on the plates. (U.S. Air Force photo by 2nd Lt.
