Steel Brethren

The Steel Brethren, also known as the Steel Brotherhood, are a warband of Chaos Space Marines drawn from the Iron Warriors Traitor Legion. They have been noted to make extensive use of gunship transports and Drop Pods in their planetary assaults. The Steel Brethren, like all warbands of the Iron Warriors, possess extraordinary skill and experience in siege warfare. The Steel Brethren, when away from the Iron Warriors' Daemon World of Medrengard, operate from the Chaos Cruiser identified as the Ferrum Invictus.

Warband Colors
The Steel Brethren wear primarily metallic, steel-coloured Power Armour, with black on the inset of the shoulder plates, essentially a minor variation of the standard colour scheme employed by the Iron Warriors.

Warband Badge
The Steel Brethren's warband badge is two red Iron Halos that are interlinked on a black background.

The Siege of Vraks
  The Steel Brethren were one of the 11 warbands of Chaos Space Marines who heeded the Alpha Legion Chaos Lord Arkos the Faithless' call to the Imperial Armoury World of Vraks Prime to take part in the slaughter and mayhem that marked the the 17-year-long Siege of Vraks by Imperial forces.
