F.E. Warren Air Force Base in Wyoming has fired one of its senior officers.

The firing of Col. Donald Holloway was announced Thursday. He served as commander of the 90th Operations Group at the base.

Col. Tracey Hayes, commander of the 90th Missile Wing, cited a "loss of confidence" in Holloway's ability to lead.

The move came as the Air Force fired nine mid-level nuclear commanders and said it would discipline dozens of junior officers in response to an exam-cheating scandal that spanned a far longer period than originally reported.

Hayes says Holloway's departure has nothing to do with the cheating scandal at Montana's Malmstrom Air Force Base.

F.E. Warren is headquarters for the organization in charge of all 450 U.S. intercontinental ballistic missiles.
