Ultimately the Base Commander and Commander of Base Security.
The base or unit commander.
Installation Commander
Most likely, there isn't much of one. The First Sergeant will know who the Post Commander is, but won't have much reason to interact with them, as they'd be quite far removed from each other as far as the chain of command goes.

Base Commander
Commander is a base word. Command is the base word- er is the suffix. A base word can stand alone and has meaning. A root word is a basic word with no prefix or suffix Added to it.
If it is not dictated by a higher headquarters, then I would say it is up to the Brigade Commander. The Rear Detachment Commander would have to be authorized with sufficient UCMJ authority. Maybe a Lt. Col or Major. If the Brigade Commander was also the local Garrison/Base Commander, then that may complicate the matter, unless the Brigade Commander has a standing Deputy Commander for Base Operations.
