The Blood Knights primarily wear red Power Armour, including the power pack, upper torso, groin area and legs. The shoulder plates, helmet and Aquila or Imperialis on the chest, are white. The dark red squad specialty symbol -- Tactical, Assault, Devastator or Veteran -- is indicated on the right shoulder plate. A white Gothic numeral centred on the squad specialty symbol indicates squad number. The colour of the left knee guard indicates company number in accordance with the Codex -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), etc.
The Blood Knights' Chapter badge is a pair of ebon, crossed swords, with the blades pointed downwards, centred on a field of white.
