i dunno, i dig the ideas of ninjas on the battlefield, so it's not too accurate, but neither are demons and evil zombie bull riders...

they could be a band of like 6-8, very very highly trained (maybe not much armour, but very very good defensive skill) units that could hide anywhere. I could see them as being impervious, or at least very very hard to hit with arrows (think cheesy kung fu movies, dodging and blocking tons of arrows) but i don't know if vs arrows and vs other weapons are two different and independent factors...


they themselves could have a few ranged weapons under their sleeves, maybe able to throw 2 or 3 volleys of shurkien.
