The Iron Crusaders is a Loyalist Space Marine Chapter of unknown Founding and origin. Almost nothing is known about this Chapter in Imperial records. The Iron Crusaders were last seen in 998.M41 heading towards the forbidden region of space known as the Ghoul Stars.
The Iron Crusaders predominately wear light grey Power Armour. The shoulder plates, helm and the Aquila or Imperialis on the chest plate, are maroon. The open-faced, white squad specialty symbol -- Tactical, Devastator, Assault or Veteran -- is located on the right shoulder plate. A white Gothic numeral is stenciled in the centre of the squad specialty symbol, indicating squad number. The colour of the left knee 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 Crusaders' Chapter badge is a white Iron Halo symbol, with an orange-red roundlet in the centre. An ebon, tilted cross pattée is superimposed on the roundlet. A large white skull is then superimposed on the cross symbol. The entire symbol is centred on a field of maroon.
