Since you are TPU USAR, different rules apply. The term SRB generally refers to active duty bonuses (RA and AGR).
You will be authorized payment no earlier than the effective date of your contract as described on the DD 4/1 item 8 b. The process should be automatic provided the contract was executed correctly, it is uploaded and approved in RMS, and your ETS has been updated. We consider 1 month to be the maximum acceptable delay in payment.
When DFAS receives it for pay, your name will show up on the reenlistment tab at https://usarcintra/dcscompt.ww...RMSbonusesforweb.htm
(LAN access required).
If you don't receive payment in a timely manner, don't go to your unit or finance. Your career counselor will process the bonus inquiry.
