They strong sides : great just great - machines - organ cannon, flame cannon, flying machine -  likehelicopters with cannon and droping bombs.  Lots of dwarfs infantry can shot, infranty is tough and skillful in close combat. Deamon Slayers are special forces against deamon - very strong, and very tough.

Weakness : they cant use magic, only runes. They are static and slow (low movement range) . Its hard side to win with anybody who can play. 

I realy dont like this side- they can only stand. And thats it. Almost every single unit is faster then dwarfs.
