I believe its beyond just being able to serve. Lets say you retire as a chief after 25 years. Twenty years later you rob a bank. Jury finds you guilty of felony theft. Bye pension. Lets say you get a miracle and the jury says misdemeanor and 3 years in jail......you keep the pension. Could the military ask for a review? Perhaps and take it away anyway, but most likely wouldnt go into the weeds that far down the chain. An admiral being more of an interest story might catch some attention in same scenario.
Good explanation. Thank you!
