The Inspector General and JAG Corps will still be operating to keep some kind of order among the US Armed Forces no matter where they are stationed... and this is an encounter group that would be good for campaigns that are set prior to 'The Escape for Kalisz' or even afterwards during those campaigns that are set in units that were not part of the 5ID...
The CID team would investigate the major crimes impartially with the local MP detachments.
The judiciary detachment would set up the court that would hold a full courts marital instead of the usual commander's non-judicial punishment for lesser offensives could handle.... While the MPs would be there to provide defense for the detachment as they travel from cantonment to cantonment in a manner like Circuit Judges of the Old West.
While the majority of offenses would be some kind of NJP of hard labor while you're sleeping in the stockade, there are still offenses that would would warant a higher authority that is outside the controls of Divisional or even Corps command (and thus a higher rank held by the military judge). And the Courts Martial proceedures would need to be tweaked to deal with the composition of the Jury for offenders who are of a higher rank than Major.
Note: I have edited the location of the CID Team to make it easier to understand that the protective detail was to protect the judiciary detachment.
