This undated handout photo provided by the US Air Force shows Col. Robert Stanley II. The Air Force is firing nine mid-level commanders and disciplining dozens of junior officers at a nuclear missile base in response to an exam-cheating scandal that spanned a far longer period than originally reported. No Air Force general is being punished, but Stanley, the top commander at the Montana base, which is where the exam cheating was discovered in January, has resigned. (AP Photo/US Air Force)
