Changes

The Mark VI prototype design (which bore the provisional designation of Mk V at the time) was field-tested during the [[Scalland Campaign]] by Legionaries of the [[Raven Guard]], whose experiences and comments resulted in improved design features in the finalised armour mark. Mark VI armour offered no better protection-levels than the Mark IV, but incorporated more efficient internal systems where power-routing and auto-sense were concerned. Power systems were given back-up redundancies with no increase in weight, while both olfactory and auditory sensors were improved. Additionally, the armour featured the best stealth capabilities of all power armour marks so far designed,{{Fn|6}} as well as a new method of compartmentalising components that allowed them to be swapped out with pieces from previous marks with ease.{{Fn|1}} It is the lightest variant of power armour and featured dual technology circuits that allowed the replacement of rare or sophisticated parts with common or basic alternatives. It also included fail-safes such as duplicate power cabling.{{Fn|8}} It also distinctive for its conical nose – designed to house additional systems including advanced auto-senses. The studded left shoulder pad, taken from the previous MkV pattern, commemorates the glory of those heroes who stood at the Eternity Gate alongside the Emperor himself.{{Fn|17}} Other version said that studded shoulder pads shows the parts were additional ceramite armour was bonded to the armour - due to the need for quick field repairs.{{Fn|65}}
