I did already accept the 15 a little while back. It wasn't worth trying to fight it. They didn't go for anything remotely near what was lied about, only what I had done, ended, and owned up to. It's extremely minor and complete overkill to be a 15 in my opinion. I talked to one of the other leaders involved who told me the wg/cc was dead set on crushing me, the 15 was no bluff.
My home-station leadership has had my back the whole way. I know getting promoted is about 99% out of the question, but if I can stay an O-4, hit 20, and keep flying, I'm perfectly happy with that.
