I'm building my own homebrewed Primaris Chapter and I started to wonder, how necessary it is to show Marine's Battlefield role on their armours?
I have placed the Chapter badge on the left pauldron. Company iconography on the right. And squad markings on the right knee plate. So I'm running out of spaces and I really wouldn't like to add another marking on the left knee plate, because the armour would be looking cramped that way.
For your consideration, I'm doing Space Wolves successor Chapter.
