Hellenic Medium Cavalry, Campainian Cavalry, etc....

Is there some reason why i cant recruit hellenic medium cavalry, Campanian Cavalry, Karian warbands, Elitle Thracian Infantry, Machimoi Native Infantry etc.... Ive build all the MICs and used all forms of government or the regions, even using different factions like Makedon, Romans, Seluceia, Ptolemyand i still can recruit certain units. Are they just like not activated or something of the sort? Where they juts not put into the game?

Not all regionals are available to every faction. And those that are may be only in a very small area. For example, the Karian Warband is only available in Halicarnassos and Sardis on a level 3 or 4 regional MIC.

Look for the unit cards in the 'documentation' folder (installed to your EB folder) for more info on where and when you can recruit certain units.
