'''Servo-skulls''' are drone-like devices fashioned from [[human]] skulls – often those of pious [[Imperial]] servants, low-ranking [[tech-adept]]s, [[Tech-priest]]s with unfinished work, or loyal adepts of the [[Adeptus Terra]] – and then given a rudimentary [[Machine spirit]], support systems, and anti-gravity engine to allow them to hover and drift bodiless through the air.{{Fn|1}} Presumably this chance to continue their work even after death is a great honour in the Imperium.

==Servo-skull patterns==

'''Aggression Enhancer Servo-skulls''' are used by the [[Adeptus Mechanicus]] and are equipped with binharic speakers. They constantly blurt out the [[Omnissiah]]'s benedictions to smite the unworthy, and use [[Beta-wave generator]]s that stimulate the aggression centres of biological and cybernetic minds alike.{{Fn|4}}

'''Data Skulls''' contain a data screen set into their backs. This makes them the perfect item for relaying important targeting data, recording the findings of [[Inquisition|Inquisitorial]] investigations and many other uses.{{Fn|8}}

'''Gheistskulls''' are made from the skulls of deceased [[Imperial Navy Breacher]]s and carry compact explosives. They accompany Breacher teams, during boarding attacks.{{Fn|11}}

The '''Guardian-Skull''' serves as an uncommon but effective personal bodyguard. It has a somewhat reinforced structure and mounts a single weapon system guided by a targeting selection program. Guardian-Skulls are further subdivided into two different types, depending on weapons configuration.{{Fn|18a}}

The '''Gun-Skull''' can mount a single firearm from a selection of pistols or other compact weapons, but usually wields an [[autorifle|autocarbine]] or [[lascarbine]]. It also carries a red-dot laser sight.{{Fn|18a}}

Mono-task '''Infoslave Skulls''' make ideal lookouts for the [[Adeptus Mechanicus]], to watch against the sudden deployment of enemy troops.{{Fn|6a}}

'''Monitor Skulls''' are used by [[Alecto (Hive World)|Alecto's]] [[Varangantuan Enforcers]] and patrol with the [[Enforcer (Security Force)|Security Forces]]' squads{{Fn|13a}}. Their red ocular sensors{{Fn|13b}} are equipped with facial recognition systems, so the Servo-skulls can scan the [[Hive World]]'s citizens for wanted fugitives{{Fn|13a}} and their spinal columns end in a viciously curved barb the Monitors can use as a weapon. They also patrol the Enforcers' Bastion headquarters and give vocal alarms of ''"Unauthorised weapon detected."'' to summon the Enforcers, should their scanners discover a civilian has entered the buildings with weapons.{{Fn|13b}}

The '''Monotask-Skull''' is the most common form of servo-skull. It specialises in a single task and is fitted with the required equipment. Most Monotask-Skulls also mount a basic set of extendable manipulator pincers, onboard navigation and a pict-relay to record or to transmit visuals back to its owner or to a linked [[cogitator]].{{Fn|18b}}

====Auger-Skull====

The '''Auger-Skull''' mounts an [[auspex]] and a [[vox|vox-data system]] to transmit information.{{Fn|18b}}

====Courier-Skull====

The '''Utility-Skull''' mounts a multi-tool to perform simple preprogrammed maintenance tasks. It can also be remotely-operated by its owner to perform functions in otherwise inaccessible areas.{{Fn|18b}}

'''Servo-Designators''' are used by the [[Astra Militarum]]. Released as swarms from modified [[Valkyrie]]s, these high altitude servo-skulls analyse targeting data from ongoing combat operations to provide updated firing solutions to the troops operating in the theatre.{{Fn|19}}

The '''Skull Probe''' is a military device utilized by [[Space Marine Chapter]]s for reconnaissance. It is capable of moving by stealth, and can fly faster than most units can move on foot. The Skull Probe is also capable of detecting other units concealed by stealth technology. Though unarmed, they can generate an electromagnetic pulse that temporarily neutralises an enemy structure, though the Skull Probe will be destroyed in the process.{{Fn|2}}

'''Shroud-Skulls''' are specialized Servo-skulls that are equipped with [[auspex]] dampers, [[vox]]-stummers and electroshrouding incense. Small flocks are used by [[Phobos Strike Team]]s to surround an encampment, before the Shroud-Skulls use their equipment to conceal it from inquisitive foes.{{Fn|10}}

'''Spider Cyber-Familiars''' were Servo-skulls that crawled on the ground with six bladed legs and had two clawed arms on their fronts. They acted as Familiars for [[Space Marine Legion|Legionaries]] during the [[Great Crusade]] and [[Horus Heresy]], while also being able to follow orders and operate independently, far from their owners, if need be.{{Fn|21}}

'''Tome-Skulls''' are Servo-skulls that carry [[List of known Imperial literary works|Imperial tomes]].{{Fn|12}}

''Vox Skulls'' are Servo-skulls that are equipped with [[Vox]]es.

'''Watch-skulls''' are Servo-skulls that help their owners search out foes in the dark.{{Fn|16}}
