Notable CampaignsEdit

  • Third War for Armageddon (999.M41) - The Omega Marines participated in the Third War for Armageddon, deploying the entire Chapter. Most notably, the Omega Marines deployed 9 Dreadnoughts, led by Brother Weylands, to support 8 Dreadnoughts of the Angels Porphyr Chapter in defence of the Ghattana Bay water processing plant's Gate IX. In the largest reported instance of cybernetic combat in Imperial history, this Astartes force was able to defeat an assault of equal size by Ork Killa Kans and Deff Dreads.

Chapter AppearanceEdit

Chapter ColoursEdit

The Omega Marines wear a unique halved-heraldry -- divided into both white (right side) and black (left side) coloured Power Armour. The Aquila or Imperialis on the chest guard is a dark yellow colour. The black coloured squad specialty symbol -- (Tactical, Devastator, Assault and Veteran) -- is located on the right shoulder pad. A white coloured Roman numeral is stenciled in the centre of the squad specialty symbol, indicating squad number. The colour of the shoulder pad trim indicates company number in accordance with the Codex Astates -- i.e. white (1st Company), yellow (2nd Company), red (3rd Company), green (4th Company), etc. Veteran Marines wear helmets painted entirely black in colour.

Chapter BadgeEdit

The Omega Marines' Chapter badge is a white coloured Greek letter "Omega", with a large bone-white coloured skull superimposed over it, centred on a field of black.
