3,000 Sergeants in the Barrel?

3,000 Sergeants in the Barrel?: The Air Force says it has notified more than 3,000 staff, technical, and master sergeants that they are vulnerable for retraining in 2006. If the service does not get enough sergeants to volunteer to retrain from overstaffed career fields into those with chronic shortages, it will, as it did last year, nominate candidates for career shifts. (Check the Air Force Personnel Center Web site for the latest vulnerability lists.)
