The Air Force's No. 2 officer for nuclear missiles was fired Friday after "a loss of trust and confidence in his leadership and judgment," the Air Force said in a statement.

Maj. Gen. Michael Carey, deputy commander of the 20th Air Force, was relieved of command after an inspector general's investigation into his behavior on a temporary assignment.

The allegations do not involve his responsibility for nuclear weapons, said Brig. Gen. Les Kodlick, the Air Force's top spokesman. They also do not involve sexual misconduct.

Kodlick said the investigation involved "reports of misbehavior," which he did not characterize.

The 20th Air Force is headquartered at F. E. Warren Air Force Base in Cheyenne, Wyoming and is responsible for three intercontinental ballistic missile wings.
