The Air Force fired nine mid-level commanders at Malmstrom Air Force Base in Montana today in response to an exam-cheating scandal.
Dozens of junior officers are also being disciplined in moves announced by the US Secretary of the Air Force today in Washington.
The most-senior commander impacted by the scandal is Colonel Robert Stanley.
He was allowed to resign his post as commander of the missile wing at Malmstrom.
The commanders of the Wing's three Squadrons were fired, as were the commander and deputy commander of the operations group at the Montana base.
Members of all three squadrons at Malmstrom were implicated in the cheating, either by providing or receiving test answers, or by knowing about the cheating and not reporting it.
