Maj. Gen. Sam Barrett, 18th Air Force commander, delivers a speech during the 317th Airlift Wing change of command ceremony at Dyess Air Force Base, Texas, July 24, 2020. While traditional change of command ceremonies enable outgoing commanders the chance to assemble their personnel for presentation to the incoming commander, this change of command was conducted with limited guests in attendance to allow for social distancing to take place.
