I am missing retirement points. Who can I speak with to fix this?

Depends if you're in the IRR/IMA or a TPU unit.

If you're in a TPU unit, then it's through the unit up to USARC (they will use the RLAS* system for point corrections).

If you're in the IRR or IMA program (not DIMA .. those go through the supported unit), then it's up to HRC* (see appendix B-2 of reference).

By the way, did you hear back from the SELCON board?

If you're a TPU Reservist or M-Day NG, you'll need to speak with your S1 or RPAC, and present documentation showing participation. Duty/Pay Roster with your signature showing goes a long way of proving attendance.

Just a note Sir, it took me over a year to get my points corrected. I went through my TPU . They ended up submitting it twice before the change took. Just keep your LESs, those are the key to proof.
