CM,
You will get 13/16 accrued AFPS 75 benefits when you leave. You will then get 3/16 accrued FAFPS benefits at state pension age (68 for you?). This, I think, is the problem for many people.. there is a gap which has to be filled.
The examples don't cover anyone in your particular situation - which ios frustrating. Although they can't cover everyone, I am sure that there are many more officers and SNCOs who will be in your position.
