I have started a Tyrant's Legion force at the moment, I am working through the my first cohort (around 15) marines and my Retaliator squad. I have gone for silver and blue shoulder pads as per IA9 using silver trims and the Tyrant's Claw. I am reserving the gold trims and Astral Claws Heraldry for Officers and veterans units. The only markings additional markings (once batches are done) will be the Maestrom Warders symbol.
I am expecting my first bit of armour today (Medusa Siege Tank) and bits for Arch-Centurion Cornac Commodus.
