Alabama's RCV law for Military and Overseas voters is the best example of such RCV laws: it describes the RCV process used and how RCV ballots are to be sent to military and overseas voters. Like all other military and overseas voter RCV laws, it provides only basic instructions on ballot counting, how ballots should be designed, and how to adjudicate ballots. Mississippi's regulations cover similar ground.
