The Chapter makes wide use of the "beaked" and older marks of [[Power Armour]] (Mk. [[Mark IV|IV]]-[[Mark VI|VI]]). After their near-destruction at Isstvan V, the Raven Guard techmarines created ''ad hoc'' suits using salvaged parts and components from other suits or vehicles.{{Fn|12k}} When the battle barge ''[[Avenger (Battle Barge)|Avenger]]'' returned to Deliverance, the Raven Guard received a shipment of 2 000 suits of Mark VI Power Armour. At that time, the Mk. VI, designed as the "Corvus suit", was the newest and most advanced version. Because this mark of Power Armour carries the name of the [[primarch]] [[Corax]] it is natural that the Raven Guard feel a bond to this mark of armour.{{Fn|12i}}
With the initiation of [[Primaris Marines]] and the [[Mark X]] armour, Raven Guard marines frequently make use of the [[Phobos Armour|Phobos variant]], due to its lighter weight.{{Fn|36a}}
The Raven Guard's chapter planet and base of operations has the production capacity of a small [[forge world]], ensuring that the Chapter rarely lacks for the material to prosecute its campaigns.{{Fn|4a}}
Raven Guard power armour utilises enhanced cooling systems that which helps it to blend in better with the background. This means Raven Guard Marines are harder to detect by thermal or infrared devices.{{Fn|11c}}
====Fleet====
During the [[Horus Heresy]], the Raven Guard's fleet was equipped with special stealth technology: a ship's [[void shield]]s could be modified so that they provided only minimal protection, but at the benefit of making the vessel nearly undetectable either visually or by sensors. It took only a few minutes for this adjustment to be made.{{Fn|12a}} The Raven Guard also operates a stealthy variant of the [[Thunderhawk]], the [[Shadowhawk]].{{Fn|30a}}
