Is it possible that the peasants aren't peasants?
Do all factions have to have peasants?
I think they don't look like it and Turks being semi-nomadic and not having a "feudal" structure it could be that they are another light troop of some kind. If you compare them to the Portuguese pitchfork wielders they have a more military professional look. Also what's their weapon? Doesn't look like a tool....
