The following few thoughts were "inspired" by what was being discussed in the 'RR Logic' thread
What IS, in fact, the role of garrisons in this game? Aside from the 'RR Logic' blocking insane enemy train rides behind your lines?
I, for one, (playing CSA only) strip all the cities of the deep south off everything, sometimes leaving an odd BDE in a better fort here and there (I also dismantle most of the forts and/or downgrade their weaponry for reduced support costs, but that's another story), but never in the cities. I've never had any enemy RR movement behind my lines anyway.
OK. So here go my points:
1. When a governor or another demands a mumber of BDEs in his state, this is, in my case, served by "fighting units" - in containers. No governor ever demanded units to be garrisoned. If, in case of governor's demand, a garrisoned unit counted, say, as 2, as opposed to units in containers counting as 1, this would ask for a temporary "garrisonification" until the governor is happy and lets go. As it is - no point here.
2. When a province goes to unrest, it can only (or am I wrong?) be suppressed with units in containers. Garrisons do not help here. Well... what do those guys do? Sit behind their barracks walls playing cards while the city is run by angry mobs? "Gangs of New York" come to mind.
3. I do not recall ANY bonuses related to presence of garrisoned units in cities, although I would like to think that provinces with garrisoned units in them should have lower chances of unrest, and/or higher chances of successful "pressurizing" the populace, be it for goodies or recruits...
Did I miss something about governors' attitude being related to presence of garrisoned units?
Please let me know if there ARE any uses for garrison units, aside from the RR control, and the obvious replacement pool for the front (which, useful as it is, has nothing to do with the units actually being garrisoned - quite the contrary).
