Omega Marines

The Omega Marines is a Loyalist Codex Astartes-compliant Space Marine Chapter of unknown genetic lineage that was founded during the 40th Millennium. 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 purely cybernetic combat in Imperial history, this Astartes force was able to defeat an assault of equal size by Ork Killa Kans and Deff Dreads.
