Thank you WaitingonPeblo... This is definitely feeling like fly by the seat of ones pants as few in the positions seem to have the answers. For me as I'm likely to not get any CRSC based on the numbers, I'm doing my best to understand the interactions of the rest of the various pays. Retiring from Fed service and then military seems to be backwards compared to most and that's apparently confusing. As an example it appears I cannot by back any new military time.@DaveK - Yes I am learning all of this real time trying to navigate it. DFAS had me on hold talking with multiple different supervisors, and they all came back with that answer - once you waive MIL PAY for purposes of FERS Credit - someone who is fully entitled to CRSC / receiving CRSC would then forfeit that eligibility. Which is odd to me because I explained to them my Ret. MIL PAY is $3688 pre-waiver and $0 post-waiver, so "waiving" $0 / month (what is even being waived?) forfeits all CRSC eligibility....
It was also disappointing to hear about the timing of the action. DFAS told me that you forfeit CRSC immediately once the request is processed, NOT when you finally hit your FERS retirement date and begin to collect those FERS payments...
This is totally separate from MRSA - but again another example of how medical retirees are short-changed.
And thanks Mr. Ron.
