The Department of Defense will implement the new Blended Retirement System (BRS) in less than a year. All Airmen should take advantage of training and informational resources to research their options during 2017. The Opt-In course is designed to provide sufficient information for eligible Airmen to make an educated decision. The training (course number J3OP-US1332) is now available via Joint Knowledge Online. The Air Force recommends all Airmen take either the Opt-In course or the BRS Leader Training on JKO (course number J3OP-US1330). The leader training course is also available to those without a Common Access Card — to include family members — via an alternate website. BRS information is continuously updated on myPers.
