More than 130 US Air Force airmen who believed they had secured promotions to technical sergeant have instead been told those promotions are being revoked after officials discovered a major scoring error in a key advancement exam.
The unprecedented mistake changed the outcome for 270 airmen after more than 2,200 promotion exams were rescored, with 135 previously selected candidates losing their promotions and another 135 taking their place because an outdated answer key had been used.
