In Rome and Central-Northern provinces (the ones bellow the Gallic tribes) you will get Roarri, Hestati, Equites, and General. In the Central-Southern you will additionaly get Celto-Hellenic spearmen and Samnitees.

In the two most southern you will get all Greek with the addition of Samnite and Roman General.

The northern are Gallic and the new native Italic tribe (I forgot the name).
