The United States Air Force has suspended 34 officers responsible for launching nuclear missiles over allegations of cheating in a proficiency test.
The cheating allegations emerged during investigations into alleged drug use by personnel at other bases.
Air Force Secretary Deborah Lee James said the cheating involved officers based in Montana and related to a monthly test all nuclear missile staff must take.
"There was cheating that took place with respect to this particular test. Some officers did it, others apparently knew about it and it appears that they did nothing, or at least not enough to stop it or to report it.
"This is absolutely unacceptable behaviour and it is completely contrary to our core values in the Air Force."
Nearly 200 officers will have to re-sit their tests under strict supervision. Three other officers were suspended for possessing recreational drugs, the BBC reports.
