I will left minor native and allies/repentant units for another thread.
So, DE and African Royals have brought new mercenaries. Just for fun to write, because implementing this could have gameplay changes that I don’t know if they would be benefitial.
*Askari: late colonial african soldiers. Could be used by British, Germans, Portuguese and Spanish.
*Zouave: French colonial north african soldier.
*Napoleon gun: Obusier 12, originally French. So for them.
*Zeneta rider, Sennar and Kanuri cavalry: Ottomans
*Gatling camel: they represent egyptian units, so its fine being revolution only.
*Cannonner: they represent early port/spanish gunpowder units in Africa and America, so for them. Specially for Spanish could be the solution for who ask for armoured arquebusiers, without adding a new unit to balance.
Also maybe some old xpack mercs could be added to old civs, for example:
*Jat lancer: British
