I know you made all the units in FATW into "is_peasant", so they only count for half their manpower when it comes to "suppressing" unrest in your cities.
I was just wondering if maybe it was possible to create some faction wide police units. Guys with only light armor and wielding a nightstick.
Maybe make it so they need 2 turns to train and can only be done in your homelands, requiring highest level barracks (or possibly the highest lvl city government building you can get to, as well as the unbuilable palace for the unique cities).
But quite cheap in upkeep, they are watchmen after all, and not soldiers.
A unit for keeping order in the cities in your controlled territory, takes long to recruit and is really horrible in combat, capable of taking on peasants, but not much else. Maybe only available in smallish units, so make it even tougher to get a lot of them very quickly.
Something to produce slowly in your cities far from the frontier, that are slowly growing and needs someone to smack the populace around the head when they are starting to get a bit too revolutionary.
( I mean, all the factions are monarchies, can't have some people running around and talking about republics and Liberté, égalité, fraternité, god only knows what something like that may lead to.
The only ones lacking that special attribute (is_peasant) is Dunland warhounds and catapult, ballista, Mumakil and olog-hai. And of those, only the first is really of any use as a policing unit. Catapults and ballista just doesn't contain enough men and mumakil and olog-hai are too expensive in upkeep.
Dunland warhours works pretty nicely tho, not very costly for such a big unit, and then add in that they give double "garrison bonus".
Also, easterling warbands have spears, but not the spears attribute, so they are wielding spearlike swords, same goes for their horde brothers. And the gondor militia levy still have their full attack, unlike their Adunabar militia levy, which has it decreased, essentially making gondor militia levy better than gondor swordsmen levy.
