The Iron Ravens are specialists in sudden, shocking drop assaults. Their 10th Company elements may spend solar months building up local intelligence and preparing the ground so that, when the main body of the Iron Ravens force comes screaming down into battle in their Drop Pods, they strike with such decisive and destructive precision that the war is won with a single, unstoppable sword-blow. The Chapter has taken to calling this tactic "the Blade of Corax."
As a consequence of this experience, Iron Ravens Astartes are more flexible in tactics and combat doctrine than other Raven Guard Successors. They learned how to be more flexible in battle from the other Space Marines of different lineages they fought alongside during the crusade.
The Iron Ravens are not dedicated solely to the use of stealth as a tactic like their parent Chapter. They are firm believers in gathering enough intelligence to adapt their tactics to whatever situation or type of enemy they face.
As a newly-raised Chapter, the Iron Ravens are determined to become the masters of their own destiny in the years ahead, displaying the fortitude and iron resolve that will match their name.
In general, the higher in rank an Iron Raven rises within the Chapter, the more blue they display on their Power Armour.
Veteran status is indicated by having the armour covering the arms painted blue.
In the Iron Ravens, every single rank in the Chapter can be identified by the colour of the helmet.
The Iron Ravens' Chapter colours are silver, blue and red.
The colour of the shoulder pauldron trim designates company according to the dictates of the Codex Astartes.
The white squad specialty symbol -- battleline, close support, fire support or command -- is displayed on the right shoulder pauldron.
The squad is indicated by a Low Gothic numeral on the left knee plate.
The Iron Ravens' Chapter badge is a stylised white raven centred on a field of blue.
The Iron Ravens were originally identified in the Soulbound audio book by George Mann as a Second Founding Successor Chapter of the Raven Guard. The Chapter's forces were presumed lost on the world of Taltos.
In August 2019, the Iron Ravens were revealed as a Chapter created by Paul Norton, a Games Workshop 'Eavy Metal team painter, that was showcased in a Warhammer Community article. The Iron Ravens were included as a canon Chapter in the forthcoming Codex Adeptus Astartes - Space Marines (8th Edition, Revised Codex).
It is unknown if the original version of the Iron Ravens still exists, or has been ret-conned into this new version.
