Because we certainly would not be able to make new units for all factions on the map we have tried to make more interesting rosters for the more exotic factions by 'extracting' from the Vanilla units and their upgrade models those that would be least awkward and give them new roles. Here are the first examples:
al-Murabitun (the Moors)
The Berbers would be the core population. They are available in Africa and Spain, but as a highly mobile people, would follow the Moors to every conquered province
Berber Tribal Horsemen, Berber Tribal Warriors
and Berber Noble Guards
Arabs live in Africa, the Levante, Spain and Southern Italy.
Arabian Tribal Warriors
with archers, skirmishers and spearmen.
Arabian Urban Militia
and Arabian Raiders
the unit in game has horses
and Noble Faris
(the mounted versions only)
This is the military of the Taifa
states that dominated Spain since the collapse of the Cordoban Caliphate. They mix elements of European and Oriental warfare. They are available in Spain only.
and Taifa Crossbowmen
Even though the Arabs prefered the bow over the crossbow, crossbows became rather popular for castle garrions in Spain.
Taifa Horse Archers, Taifa Horsemen
and Taifa Nobles
These would be the core units of the Taifa states.
Taifa Urban Militia
and Taifa Volunteer Swordsmen
These are only available on Jihad
These are (former) Christian nobles that converted to keep their lands and titles. They are available in small numbers in Catholic regions.
Muwalladun and Dismounted Muwalladun.
Mercs from sub-Sahara Africa are available in rather limited numbers in N-Africa and the Levante.
African Warriors, African Skirmishers
and African Archers
al-Salajiqa al-Rum (the Turks)
The Turks are a complete different people to the Arabs and Berbers, there would also had not been any Arab population of notable numbers in Anatolia, so their units cannot be the same as those of the "Moors".
These feudal units would have formed the backbone of any Turkish army
and Turkish Horse Archers
The Seljuk Nobles would also become the new bodyguard for the Turks. The unit in game has horse armour.
These were often raised in large numbers by the nobles in order to fullfill their quota in troops to deploy for the Sultan.
and Dismounted Herdsmen
These are war-slaves. The usage of slaves as household troops had a long tradition in the Near East; but the Seljuks of Rum had never been as rich as the Egyptian Ayyubids or the later Ottomans. That way their war-slaves did not become as important as the Mamluks or the Janissary.
and Ghilman Horse Archers
and Ghilman Spearmen
These are Turkish mercenaries from Central Asia available in the south-east of the map.
