Techmarine

A combination of Space Marines and Tech-preist Enginseers, they are the Space Marines' mechanics, armourers, and technicians. They are loyal to both the Cult Mechanicus and their chapter. A space marine that shows a speshulty towards machinery will be sent to Mars for a number of years to learn how to "master the Machine Spirit" and all that Omnissiah shit. Their armour is modified to fit their servo arms and backpack and is usually painted red to show allegiance to the Cult. Their chapter badge and colour is shown on their pauldrons instead.
