brian8225,
Sorry to hear about your letter from the RMO. Do not be discouraged though. As stated before there is an appeal process. Read the letter carefully, in it it will state exactly why you do not meet UoS. You stated earlier that you still need to wait 3-5yrs to be medically clear of the CA. perhaps that is the reason and you will have to wait. I do not know, I have not seen your file and I have not worked the medical side of recruiting in a number of years.
Be patient, hang in there. If you are not sure, contact the Medic/PA/Sgt at the Medical Section of the Recruiting Center and speak to them about it, they are the SME's and can explain it to you. Speaking from experience. Go in person if you can, bring the letter. They have a copy, but it's been filed already. They will be able to explain what you will need to challenge the decision and how long you will have to wait.
Good Luck, Don't Give Up
