List of new historical units to add in the game

New historical units to create. Please specify their characteristics and historical periods.
I created "auxiliary cavalry", a sort of horse peasants, and Norman knights, just like Feudal Knights but with a +1 Melee, special unit for the Sicilians and for English in Early period.

Good question - I think MTW did a pretty good job including lots of different kinds of units, arguably more than really existed (I am not convinced there were significant numbers of foot units armed with the sword as their primary weapon).

I compared the MTW units with the army lists from the minature rules, Medieval War, by Terry Gore, and did not notice any major omissions except maybe regarding javelins. I think a lot, may be most, factions should have access to javelin armed skirmishers, like kerns or murabitin or alumghavars. Also more factions such have access to javelin armed cav like jinettes, especially the Almohads. So I don't think there are that many missing units but some existing javelin armed ones should be made more generic.
