I suspect the JAG Manual investigation is similar to what the USAF calls an AIB, as the AIB reports are the result of a JAG process. It has to be JAG in the AF to produce any disciplinary or administrative actions. For example, an AIB can recommend a court martial or a flying evaluation board, which has an equivalent in the USN. I’ve been, in various positions, involved in several FEBs. About the same time interval, too.
