perhaps in addition to the realm name after the noble name/titles, they get a (big/medium/small retinue) tag, if they have a unit?
or even, no description of size...
something like..
X, lord of Y, realm Z and retinue. (if they have a unit)
X, lord of Y, realm Z. (if they have no unit)
The realm name could be added after the region affiliation, or this.
But I don't see any reason for obfuscating this information at all. This is just a nerf against the tiny minority of players who play a priest without playing a non-priest in the same realm for no good reason.
Traders, diplomats, courtiers, none of them are involved in the military, and they still get access to this (very basic) info.
I also question the utility of having priests not able to see troops abroad either, now that I think of it. After all, they are easy as hell to arrest. You don't need to view them as evil anymore, as it used to be back then.
