Roman Allied Cavalry

[Balbor]

Where can I recruit allied Roman cavalry from? I can only recruit the Extraordinarii, where can I get the other 2/3 of my Roman allied cavalry from without resorting to mercs?

build a level 3 auxilliary barracks to recruit all the allied roman units

but there should be allied roman cavalry other than the Extraordinarii at the same time i can get Extraordinarii. in order to get Extraordinarii i need to be able to group the 1/3 best allied cavalry together, but they are currently 100% of the allied cavalry available to me. I was wondering if I need to build the level 2 auxilliary barracks in the right region to get them?

well, I know that italia or corsica doesn't matter as I have built auxilliary in both provinces and them gave me the same units. I'm still in polybian reforms and I can recruit 4 different italian auxiliary cavalry.
Level 2 barracks you unlock 2 auxiliary cavaly, and level 3 you unlock another 2.

i haven't reach the polybian reforms reforms yet, but if I can recruit Extraordinarii i should have access to the others
