"Veterans, Essentially, a hero in their own right for when they are called to the battlefield they demonstrate efficiency and battle prowess tempered from their years of experience in campaign. As a tradition shared by the Terminator squads of the Helion Legion, All veterans will have at least one panel of their relic power armour unpainted, leaving the original colours of their Primogenitor chapter, The Ultramarines in proud display."
