Hey, I have a quick question from someone who knows the anwser. I have taken Regium a while back and have a level 1 for my homeland province (I am Romani). So I am wondering when can I start building normal barracks to recruit Roman troops? I have both native troop buildings built (Level 1 and 2) and now I am in a position to build a normal barracks but its not an option? Are there any pre-reqs for it?

I appreciate any answers.
