Centurions

A Centurion is a Space Marine who has been equipped with a powered exoskeleton worn over his normal suit of Power Armour known as a Centurion warsuit that allows him to serve a heavy ranged fire support or close support assault role between that of a normal Astartes and a Terminator. A Centurion warsuit enables a Space Marine to stride into battle with the firepower of a battle tank at his fingertips. Protected by thick ablative plates of ceramite, a Centurion warsuit renders its pilot immune to all but the most powerful of weapons. Named after the Space Marine Legion leaders of old, the Centurion warsuit design was unearthed in the aftermath of the Age of Apostasy in the 36th Millennium, and after sanction by the Adeptus Mechanicus, the suits found their way into the armouries of almost every Space Marine Chapter.
