The Air Force will spend more than $55 million to retain airmen and Space Force members who perform critical jobs in 37 specialties next year. The 2021 Selective Retention Bonus (SRB) will carry 28 career fields over from 2020, add nine more, and delete another 40. It takes effect Jan. 5. Airmen whose career fields are being terminated or reduced have until Feb. 4 to take advantage of SRB at 2020 rates. The complete list is available on individual myPers pages or the Air Force Personnel Center web site.
