I was put on TDRL on Nov 2010 and officially retired from AF about six months ago with 60%. I have a VA rating of 90%. I just received notification from DFAS that I was awarded 70% combat related compensation and just received payment of $490 for January, which is the first month I have received CRSC payment. Will I receive back pay / retroactive pay ? If so, what is the date that it will start ? Thank you!
