I went through the process a few years back, and this is how I recall it... it's entirely dependent on whether you're looking at MND or MLD, and whether you're actually any good at your job.You'll go in front of a Doc who'll chat through your records, and make a recommendation. That'll then go to the Board (3 Docs I believe) who will deliberate as to whether you're a keeper or a chucker. If you're a keeper, they'll likely recommend that you're worth keeping if you want to stay (you can state your preferences for staying / discharge etc before this all happens) and so you'll be permanently downgraded to MLD or MND, in line with your condition. They'll also dictate what your requirements are for the RAFFT (ie Rockport Walk, etc). Even if you have elected for a Med Discharge, I believe they can still choose to keep you on regardless - equally, even if you opt to stay in, they can choose to med discharge you. It all depends on exactly what's wrong with you, and how that ties in to your trade requirements, deployability, etc. Usually the manning levels for your trade would also be a factor (if yours were overmanned etc) but I don't think ANY trade is in a position to use that criteria just now.Anyone with a Med background, feel free to tweak / adjust or add to what I've put down, I can only base it on personal experience.
