In in general even me forgets the Iberians and Britons. They are more servants and rarely have slave, contrary to Spartan Ilotes.
What about his guys I think in all cultures even today exist, they can work with he other giving extra aura.

in my design militia must be the first only military with the scout in phase 1. unit the citizen soldiers appears later in early phase 2
in the barracks etc etc. The third soldier to appears are specialist( troops are elite or have special design) this appears with support advanc d units, priest etc. So the champion and siege Warfare and saving for the last the Hero. That's the pecking order.
