CRSC

I retire next year (23 years and 3 days as an E7) and I’m trying to figure out of all this retired pay, CDRP, CRSC along with VA Benefits. For CRSC, can anyone explain this accurately? Anyone receiving this? What is CDRP? Is CRSC stacked on top of VA benefits?

I’m going through TAP and the counselors haven’t been too helpful in explaining anything.
