Unless we aren't being told what is really going on, that's not how the RIF is going to work. They don't promote a certain number of pilots or navs to Major or Lt Col the entire year group competes against each other likewise they aren't going to RIF us that way either. The senior rater (wing commander in most cases) will be given a certain amount of Definitely Retain, Retain and Do Not Retain allocations based on personnel assigned and a percentage yet to be determined. From there the board will do its magic.
Although this is not gospel, this was just published by af.mil yesterday stating that the overall target will be around 2%. I don't think they know what is going on.
I'm going to put my .02 cents in again if the CSAF is listening please separate us line officers we need to be a rated line force and a non rated line force.
