Okay got new info on Fedayeen

It should be Tiley.

It is an ancient tradition in Caucasus, where in desparate times a young Circassian volunteers to become "the Tiley". Tiley are individual warriors. They are not like squads or companies.

They are usually around 15-16 years old. They wear red clothes, ride white horses.

They dont carry any defensive weapon, only offensive:

So for example no bow, but Silver Sword and dagger. a gold helmet.
They never run away from the enemy, tiley is similiar to sacrifice but without the religious susgestive weight on the word.

Tiley in Circassian means "Great Light" "Powerfull Light".

Since they are only individual warriors though maybe they should be included at all.

Although I admit I would love to see them charging by themselves infront of everyone!

So either case it is not Fedayeen or Fedayi Fedai whatever...
