The units so far (early period)
Poulain Knights
Poulain was a French word for a Frank born in Outremer. They retain western traditions and the knightly style of fighting, but have a distinctly eastern flavor to their appearance.
Poulain Dismounted Knights
Ministeriales
Free noblemen can be uncooperative, especially when you want them to leave their comfortable estates in Cyprus to go defend Outremer. The ministeriale class was created in the middle ages to be a class of serf-nobility who could hold office and serve in their lord's military without having the same rights as a nobleman.

Poulain Crossbowmen
King of Jerusalem and Cyprus
Crusader Knights
Westerners who traveled west to serve the King of Outremer and gain glory and salvation by fighting the infidel.
Crusader Dismounted Knights
The middle east is not a friendly climate for the large horses used by western knights. As a result, crusading knights were often forced to fight on foot. This resulted in a somewhat unique (for the period) style of infantry fighting. These knights fought using their lances in a screen for defense. Historically they were not disciplined enough to advance in order (an innovation made later by the Swiss), but they can form a powerful defensive line, and use their swords in the attack if they are forced to go on the offensive.
Crusader Northmen
Dismounted crusaders from the far north who use their terrible long-axes to great effect.
Crusader Marksmen
Crusader King (Capet)
Templar Knight-Brothers
Knights pledged to the military orders had something that most soldiers of the time did not--fierce discipline. These troops fight like western knights, but are better trained at fighting as a unit, and have very high morale. They were feared by the muslims such that they were often executed on the spot if captured, being too dangerous to ransom or to keep as slaves. These knight-brethren and their counterparts the hospitallers were the elite units of the Kingdoms of Outremer.
Templar Dismounted Knight-Brothers
Templar Dismounted Confraters
Confraters were men who donated large sums to one of the military orders, and in exchange were made a sort of honorary brother of the order.
