The Iron Halo is part of the Space Marine Armoury. It is an ancient artifact, a special award given to a Space Marine who has shown exceptional initiative or bravery on the battlefield. It incorporates a powerful conversion field, similar to the Rosarius or Refractor Field that reinforces the resiliency of Space Marine Power Armour, allowing them to whether even the fiercist attacks. 2
The Blood Ravens Chapter possesses a special Iron Halo, a revered relic assumed to have belonged to their unknown Primarch.1
Iron Halos are so rare that in the Ultramarines, only Captains and Company Champians are authorised to wear them.2
