Even if the Iron Warriors are not dedicated to any Chaos deity in particular in the fluff, the army has to be playable on the tabletop. I wanted a fearsome melee unit in my Core Units. And what fills this role better than Khorne Berzerkers?
That's why I painted a unit of Khorne Berzerkers for my Iron Warriors army. Iron Warriors cut off mutations and replace them with bionic implants, but this could be difficult to do with a head. That's why the sergeant has a demonic head...
