Body Guards are only mostly used to just stand around with a gun and defend the base right? Well I suggest a security addon where you can place trip alarms, small remote explosives, security drones to check the outside without going outside, and improved security cameras. He should also have a Security terminal where he can lock all property doors without the keys, able to manually set off an alarm if the trip alarms dont go off, also can check all the placed security cams all on 1 screen but max is 4 cams.
