The Emperor's Shields Astartes wear a halved-livery: light green on the right side and yellow on the left side of their Power Armour. The Aquila or Imperialis on the chest plate as well as the power pack are black. The right shoulder plate bears a black squad specialty symbol: Tactical, Assault, Devastator or Veteran. A white Roman numeral is centred on the squad specialty symbol, indicating squad number. Most unusual, this Chapter uses the colour of its helms to denote company number in accordance with the Codex Astartes -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), Green (4th Company), etc.
The Emperor's Shields' Chapter badge consist of an ebon livery shield, with a large red skull centred upon it, on a field of yellow.
