MkII Crusade Armour
MkII Armour represented a significant technological step forward from the original Space Marine Thunder Armour. Created by the Adeptus Mechanicus, it was totally enclosed and life sustaining, making it suitable for use in a variety of hostile environments including deep space. The few surviving examples of this pattern are still maintained by some of the oldest Space Marine Chapters and are venerated as sacred relics
MKV Heresy Armour
The iconic MkV ‘Heresy’ pattern of Space Marine Power Armour was first created during the dark days of the Great Betrayal. Remarkably durable and easy to produce and maintain, large quantities were supplied to the Space Marine Legions prior to, and during, the Heresy. As the galaxy spanning civil war progressed, new supplies of arms and armour for the Traitor Legions were heavily disrupted, forcing them to scavenge components from their fallen enemies
