Yes, the natives have three levels of troops:
Braves
Armed braves (with guns, equivalent to soldiers)
Armed mounted braves (with guns & horses, equivalent of dragoons).
I don't think they have mounted braves without guns, but someone here can possibly correct me.
However, your converted natives cannot be transformed into armed or mounted units.
It's a pity the natives aren't more dangerous. Unless they go hostile early, it isn't too hard to defend against them and counterattack. The real pity, though, is that the competing European powers are so useless and incompetent; they can't even defend their own territory effectively.
Natives *do* seem to demand guns & horses far more often than any other commodity. Only natural, I guess.
