Parthisan Amry out of nowhere - better organisated than any other army

The armor and chevron levels do seem to be random.

I took over Pontus' capital from the Ptolemaio, moved out of the city, and waited for it to rebel. It still had Pontus' temple I believe. Anyways, it rebelled to Eleutheroi, which didn't happen because I had built any roman buildings there, so I guess it may have tried to rebel to Pontus but failed.

I was always under the impression that the city will rebel to the faction that it has the highest cultural affinity to or the faction that held it before the new owners, when most of the buildings in the settlement was built by that faction.

The reason for my view is simple. I tend to use an army of spies and assassins to weaken large AI Empires that keep pumping out full stacks. Once you sabotage a couple of temples and merchant quarters, the AI tends to run low on money for doing anything other than fixing their buildings. I also was able to get consistent rebelleions from Ptolemaio cities to Makedonian. Also happened with a Ptolemaio city when it rebelled to Koinon Hellenon. I wasn't around the Baltic sea area when those cities fell, but I know Pella was the capital of Makedon or close enough. Pella was occupied by the Ptolemaio and when I caused it to rebell, it rebelled to Makedonia. They spawned with a bunch of arrow launchers too. That must have been due to the faction barracks that was still in Pella. That little island city west of Troy also rebelled to Makedone, and that city I know was held by the Makedonians for while, since I saw various attempts by the Ptolemaio to take it before that city fell.

The units that spawn tend to be what's available regionally or the freed slaves thing. If there are factional barracks, it seems to spawn those if it rebels to a faction. If it rebels to eleutheroi, I tend to just see a bunch of low grade regional troops.
