You report the general for breaking the activity IR by ordering late-turn moves, so he commands your lord to pull your hero character from the elite cavalry army, and has them assigned to the backwoods buro army.
I know it's just an example, but is the General technically breaking the IR? If he yells at people for not obeying the orders, then sure, but otherwise, if he's doing it consistently, he's just a bad choice of General. His solution sounds reasonable, though rather foolish... Assuming he has only two armies, he may be following the logic that the noble would be more useful in one rather than the other. Again, if he's doing it consistently, he's really banking on some pretty active players.
