The Tempest Guard primarily wears midnight blue Power Armour, which include the power pack, chest plate, shoulder plate trim, torso, groin and upper legs. The Aquila or Imperialis on the chest guard, as well as the helmet and greaves are white. The shoulder plates inset are bone white. The black squad specialty symbol -- Tactical, Devastator, Assault or Veteran -- is located on the right shoulder plate. A white Roman numeral is stenciled in the centre of the squad specialty symbol, indicating squad number. A black Roman numeral on the left poleyn (knee guard) indicates company number. The colour of the skull in the centre of the Imperialis indicates company number in accordance with the Codex Astates -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), Green (4th Company), etc.
The Tempest Guard's Chapter badge is a black winged-livery shield, with an Iron Halo crowning it, centred upon a field of bone white.
