I was medically retired from the Marine Corps. in July 2008 @ 30%. Soon after, I was rated 80% service connected through the VA. I was being paid both, until January of this year when DFAS waived my entitlement. Also, I recently applied for CRSC and was awarded 100%, however since my YOS is only 4.5 years I will only be receiving roughly $200 a month.Will I receive back pay, since the CRSC's effective date is 08/08, or am I being too optimistic?
