A physician assistant in command at F.E. Warren Air Force Base in Wyoming was fired after less than three months on the job without a detailed explanation offered by the service.

Air Force Lt. Col. Jimmy Stanley was relieved Friday as the commander of the 90th Operational Medical Readiness Squadron by Col. Johnny Galbert, commander of the 90th Missile Wing, according to the base.

The base cited a “loss of confidence” in Stanley’s ability to lead the squadron — a phrase common among the military services when a commander is fired.

Stanley, who works in aerospace medicine, graduated from the Interservice Physician Assistant Program in 2007, according to the Federation of State Medical Boards. He has treated patients in Georgia, Florida and North Carolina, in addition to Cheyenne, Wyo., where Warren Air Force Base is located.

He entered active-duty service in September 2007 through a direct appointment and has received the Air Medal and Bronze Star, among other awards and decorations, according to his service record.

Lt. Col. Tanya Berg has assumed command of the medical squadron, which provides an array of health services, including dental, family practice, flight medicine and immunizations for the base.

Warren Air Force Base hosts roughly 3,360 service members and 964 civilian employees, according to the base. It’s largest unit, the 90th Missile Wing, operates, maintains and secures 150 Minuteman III Intercontinental Ballistic Missiles.
