Chief Master Sgt. of the Air Force Kaleth O. Wright answers an Airman’s question during a base-wide “all call” at Al Udeid Air Base, Qatar, Dec. 19, 2018. Along with offering a “heartfelt thank you,” Wright discussed recent changes to the enlisted assignments system, notably base-of-preference options for Airmen as well as the advertisement of continental United States assignments for Airmen who have 48 months of time-on-station service.
