Capua allows you to build the Samniti Milites, which are much better than the stupid Pedites, when you have the right local MICs. It also can build Samnite Spearmen and some other unit.

If you have 4 of the cities listed, and it is at least 242BC, then you should see a new MIC show up the next turn.
