Yeah I konw. I tend not to use elites in great numbers cause it is both non-historical and non-gameplay wise.
Also I was not refering to the stats of each unit as to its way of recruitment and status in society.
For example, the Makedonian pezhetairoi were the equivalent of the classical greece hoplites. Citizens of a kingdom or city with full political rights such as electing officials for the army and infuencing foreign policies (war, peace, trade etc.) The klerouchoi on the other hand were mostly of greek and makedonian orgin and were given land for service as we all know , but did not have any political rights and were often switching sides in order too keep that land when it was conquered by a foreign power.
Given that the chalkaspides were an elite and the name of the unit was used as a makedonian pez. veterans I suppose that they are the the Pontic equivalent of pez. or argyraspidai in the game.
Finally I have checked the recruitment viewer and yes,the klerouchoi are recruitable through regional MICs so once again I must thank the fellow members from the previous posts for pointing that out.
