I am looking for information about if it is possible to apply for medical retirement after you've exited the Army. I have my VA rating and I need to know where to find the forms to continue from here into medical retirement (if it is possible that is). I saw on another forum that it was possible to obtain both VA and MR at the same time depending on your percentage, but no where that I have found thus far, has stated that you may CAN / NOT apply for medical retirement post Army separation. I was not medically discharged and I have very few resources to reach out to that may have the correct answers or the resources to point me in the right direction. Thanks in advance, RTC
