When making Hattin (some months ago), I realised that there are no Turcopoles in this mod. For those who don't know, turcopoles were cavalry archers recruited by crusaders to fight muslim cavalry archers. They were local riders and wore light armour.
I've just added some Turcopoles to RM2. In fact, they are just the normal archers mounted to light/medium cavalry, and can be recruited just by crusader/christian nations. I'm attaching some screenshots:
Just tell me if you are interested in recruiting them for your armies. If not, please give your reasons! Thanks =D
