The Iron Warriors needed a leader and so I decided on a Daemon Prince. Such a monstrous, winged creature will hopefully strike fear into my opponents.

I was planning to use two Rhinos as mobile transports for my Iron Warriors. I initially wanted to use normal Rhinos and convert them. I was about to buy two second-hand Rhinos but then changed my mind. On the one hand, it would cost dozens of euros. On the other hand, it would mean a lot of work.
Whilst researching alternatives, I came across the Castellan Rhinos from the Iron Warriors, which I had not heard of before. I even found some nice files to make these transporters a printed reality. It is breathtaking to see what is possible to make even with a cheap FDM printer. Apart from the smoke launchers and the hatch with the bolter, nothing is original.
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...
