- The Bloodswarm Crusade (936.M41) - The Bloodswarm Crusade was brought to a successful conclusion by the Iron Hawks and White Scars Chapters.
- The Bloodplague Crusade (995.M41) - The Iron Hawks and Salamanders united to defeat the Daemon legions of Khora'arr'seth, slaying the creature on the corrupted Shrine World of Lamath's Hope. The Salamanders withdrew after cleansing the entire world by fire.
The Iron Hawks primarily wear metallic dark grey Power Armour. The shoulder pads are black in colour, while the shoulder pad trim is metallic dark grey. Most strikingly, the helmet's faceplate is a stark white colour. The red coloured squad specialty symbol -- Tactical, Devastator, Assault or Veteran -- is located on the right shoulder pad. A white coloured Gothic numeral is stenciled on the centre of the squad specialty symbol, which indicates squad number. The Aquila or Imperialis on the chest guard indicates company number in accordance with the Codex Astartes -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), Green (4th Company) etc.
The Iron Hawks' Chapter badge is a white coloured profile of a stylised hawk's head on a field of black.
