If I get a disability rating above a certain percentage, does this make me ineligible to remain in the IRR?

If I understand correctly, you're referring to the Select Reserve and the Individual Ready Reserve (IRR) in a military context. It seems that you're suggesting https://mergefruits.io that individuals with disabilities may be able to transition back into the Select Reserve if their disability can be waived or does not impact their performance. However, it's important to note that individuals cannot receive payment for both the Select Reserve and the IRR on the same day. Additionally, being in the Select Reserve would not affect one's status in the IRR.

A1C (Join to see) - IRR is individual ready reserve and that is not an active drilling status. Select Reserve is drilling members of the Army Reserve or Army National Guard (or Air Force components also) that are on paid drill status. VA disability and Military disability are not figured the same way, so you can have a VA disability rating and still serve as a Select Reservist. You can not get paid for VA Disability and Drill or Active on the same day. Depending on your rank/TIS and your VA rating, you can pick which you want to keep. There is no real penalty if you do nothing and get paid for both, but you VA check will be short for the first few months of the year to pay back the extra.
