New unit - Mamluks

[Randarkmaan]

I think there should be three Mamluk units(all of them cavalry); Lancers/Heavy Cavalry with(you guessed it) lances and heavy armour, Horse archers with bows, swords and light armour, and bodyguards with impressive stats, discipline morale, very heavy armour and lances or maybe axes.

And one thing, someone said earlier that steppe- and Arab horses were smaller than western horses. For steppe horses this was true as they tended to resemble ponies, but the Arab horses this is not entirely true. They were similar in size to most western horses and larger than some as well, they were not as heavy though, but they were very strong and supposedly this breed of horse was smarter as well.
I'm not entirely sure about this but I think there is a hint of truth to what I just said.
