Polybian Reforms question

[We shall fwee...Wodewick]

You should get them in all Level 1s which is the original cities, Taras, Rhegion, Bononia, Segesta, and patavium. You do remember that you have to upgrade the barracks before you get the units.

EDIT: BEATEN TO IT! Damn you Quintus! If you weren't a living legend, I'd be pretty pissed.
