In the name of the Quest for Knowledge, I shall now take your head off.

"Access denied."

– Ancient Martian proverb

The Skitarii (singular Skitarius, also known as Tech-Guard; not a real word but probably derived from the Latin scitari meaning to seek to know; pronounced "ski-tar-ree") are the private army of the Adeptus Mechanicus and proof that even the Imperium could have been more grimdark.



Under the Treaty of Mars, Forge Worlds are not required to give manpower over to the Imperial Guard under the Imperial Tithe, so they are allowed to raise, train, and equip their own Planetary Defense Forces. Wait, every world is required to have a PDF so that makes no sense. Standing somewhere between the Guard and the Space Marines in terms of ability, the Skitarii have access to absolutely everything the Adeptus Mechanicus can create. The only things they don't use are the Land Raider (which is due to a decree by the Emperor reserving it for the Adeptus Astartes during the Great Crusade Horus Heresy)(like that stops the Inquisition...) and Dreadnoughts (though in theory they could, they just prefer carving up your brain and making you a servitor instead). Like the Guard, there is little standardization among Skitarii units. For example, they can't quite seem to agree if the greater unit is called a cohort or a brigade. Additionally, Skitarii will vary from simple gun-servitors under a few commanders to gene-enhanced augmented humans with major equipment.

Having existed since at least the Great Crusade, a Skitarii brain is altered to maintain their loyalty and obedience. Some are just psycho-surgically or biochemically altered, while others are full-on lobotomised. According to recent lore, one way the Tech Priests control legions of Skitarii are by messing with their brains from SPEHHS, firing off signals to make each and every one of those little bastards think they're being manipulated by the Omnissiah himself. On the plus side if, after their "indoctrination", they have anything resembling a working brain left, it'll usually be capable of some high level multitasking: a Tech-Guard officer will proficiently dual-chainsword-duel with you, while happily chatting with his fellow Skitarii on the vox in binaric cant, simultaneously catch up on his unread messages, recompiling the kernels in his cybernetic implants and trolling all the boards of future-#chan at the same time. So yeah, they're different than their service/slave counterparts. And speaking of differences, Skitarii from different forgeworlds don't always share the same look. Some prefer the classic "red-robe-with-hood" Martian style, while others wear Imperial Guard-like uniform, and some could be purely functionalist with no clothes beside armour - just name the style, and somewhere in the galaxy there is a forge world with similarity dressed Skitarii (except for THAT style, you sick fuck). One of the most popular styles the Skitarii employ is to wear fabulous fur coats, fang talismans and grizzly trophies, commonly associated with Death Worlders and Space Wolves; these are intended to terrify opponents. As if half-robot/zombie soldiers aren't terrifying enough. They can appear so terrifying that loyalist Skitarii are indistinguishable from their Dark Mechanicum counterparts to the casual observer.

They are generally the first line of defense on Forge Worlds and other Mechanicum installations. However, they also serve as marines (in the traditional sense) for some Explorator ships, and act as dedicated infantry and vehicle support for Titan Legions when they are deployed. Because the Mechanicum also likes to make friends and has allies, and Forge Worlds, everywhere, the Skitarii also serve as mercenaries or allies in many Imperial armies and crusades. Additionally, most Space Marine chapters can call on Mechanicum support should need arise. This is double so for the Grey Knights, as Titan is orbited by the former natural satellite of Mars turned into a minor forge world, Deimos, where all of Grey Knights' gear is made, and it has its own Skitarii contingent.

Also, they can be played on the tabletop, like a weird hybrid of Tau, Necron, Craftworld Eldar, and guardsma... ahem.. ASTRA MILITARUM Imperial Guard THE WALL OF GUNS, and seem to be the 40k equivalent of the Skaven, except that they're not fucking furries! Who needs Emrpah loving humies/post-humie/heretic/xenos scum anyway?! Everyone knows the Omnissiah is where it's at!

Types of SkitariiEdit

The Skitarii comes in many range and flavours, some more deadlier than the other. All of them can twist your head off and shit down you neck. Here are the examples:

Skitarii AlphaEdit

Skitarii Alphas are the squad commanders of Adeptus Mechanicus Skitarii formations. These cybernetic warriors have the highest level of augmentation among their kind, a position of high prestige in Martian culture. To become an Alpha, one must pass the Crux Mechanicus, the point where your body is more machine than flesh. Their human components have often been reduced to a simple organic brain. They are the leaders of any Skitarii and are equivalent to a Space Marine Captain.

Time to smoke out some bitches and blow....literally.

Of particular note is the fact that many Martian Skitarii Alphas were failed Imperial Knight nobles of House Taranis. Although failure to bond with an Imperial Knight typically drives the would-be pilot insane, emotive-suppressors and memory-catheters are able to keep their rages in check. House Taranis asks in return that their Skitarii cohorts are assigned to fight alongside their Knights, so that the Nobles can still fight alongside their former brothers.

Skitarii RangerEdit

The Mechanicus' equivalent of the Eldar Rangers but more Awesome. They are relentless hunter-killer infantry, and are known that they will hunt their prey across the galaxy for decades if need be. Mindful of the harsh terrain of Mars, their legs have been removed from the knees down, replaced by cybernetic augmentations. This has made their stamina legendary, and they are known to hunt a foe until it exhausts itself. Skitarii Rangers themselves are split into the Skitarii Fresh-forged which are essentially the most recent additions to a Skitarii Ranger team. They differ to normal Skitarii as their remaining flesh is still raw from the surgery involved in bionic modification. There is also the Skitarii Specialists who are given the holy duty of carrying and maintaining the Skitarii kill team’s more unusual weaponry.

Their weapon of choice are Galvanic Rifles, though others may be armed with Arc Rifles, Transuranic Arquebus', or Plasma Calivers. A Skitarii Rangers team is led by an Alpha, normally equipped with Radium Pistol or Arc Pistol as well as a Power Sword, Taser Goad, or Arc Maul.

Some Rangers control the guns on the Dunecrawler (they are the dude in the hatch).

The funny thing is, that gun is the least of your worries.

Skitarii VanguardEdit

Skitarii Vanguards, known informally as Rad-Troopers, are the other type of Skitarii infantry used by the Adeptus Mechanicus. Skitarii Vanguards are so soaked in radiation from their Radium Carbine weaponry that even to approach them is to invite death. Eventually, the radiation burns through even their heavy armor plating, slowly poisoning them to death. Mindful of the harsh terrain of Mars, their legs have been removed from the knees down, replaced by cybernetic augmentation. Their augmentations and radioactive conditioning has allowed Skitarii Vanguards to be deployed to the most hazardous war zones the galaxy has to offer.

A Skitarii Vanguard squad is led by an Alpha, equipped with either a Phosphor Blast Pistol, Radium Pistol, or Arc Pistol, as well as a Power Sword, Taser Goad, or Arc Maul. These guys are there to rape infantry in close quarters.

Vanguard are also used in the Onager Dunecrawlers as the pilot. They're basically dumped into the same kind of emulsion tank some Titan pilots get. They don't last very long but on the plus side no more getting killed by small-arms.

Sicarian RuststalkersEdit

Sicarian Ruststalkers are the elite Skitarii assassins of the Adeptus Mechanicus and an attempt to make an Eversor Assassin look like a rehabilitated good Samaritan (spoiler: a failed one). Initially an elite assassination squad, the Sicarian Ruststalkers proved so effective at the art of killing that they were repurposed as front-line, physics-manipulating commandos. Their Transonic Weapons hum and resonate with efficiency, passing through the strongest armor as if it simply didn't exist, though the effect of the damage often takes several seconds to manifest. These highly trained and augmented squads known as Killclades are led by Princeps.

As with their Infiltrator brothers, every Sicarian was once a Skitarii who was grievously injured in battle. If these fallen are judged still fit to serve the Omnissiah, they are not incinerated but instead taken back to be augmented into lethal killing machines. This process can take place as long as a Skitarius possesses a head, torso, and some limb-stumps.

Sicarian Ruststalkers also called "shivs", a reference to a way they repeatedly plunge their transonic weapons into their enemies, visible only as a blur of blue and arcing sprays of scarlet blood.

Sicarian InfiltratorEdit

AYE AYE AYE! Power Rangers! Fellow Skitarii! We request support for Zordon The Omnissiah!

The sneaky counterparts to the Skitarii forces that also bears an uncanny resemblance to Alpha-5 from Power Rangers. Sicarian Infiltrators are the brutal Skitarii scout troops of the Adeptus Mechanicus, renowned as perhaps the most sinister warriors of the Mechanicum. Heavily augmented into more machine than man, the Sicarian Infiltrators are a hideous, frightening strike force - the height of Adeptus Mechanicus posthuman engineering. When hunting, they emit from their domed helmets a white noise that fills all sensory spectrum's with static, leaving their foe disorientated and helpless and incredibly irritated. Enemies fall, deafened and blinded by the scree of a brutally disruptive audiovisual assault; battles are often decided before even a single kill is confirmed. Infiltrator squads can bypass enemy defenses with ease, though not because of their stealth but rather their disruptive wavelengths they broadcast when on the move. These scout squads are led by Princeps. Regular Skitarii warriors sent to fight alongside Infiltrators are given null-codes that can transmute their disorientated wavelength frequencies, allowing for efficient combined-arms assaults.

As with their Ruststalker brothers, every Sicarian was once a Skitarii who was grievously injured in battle. If these fallen are judged still fit to serve the Omnissiah, they are not incinerated but instead taken back to be augmented into lethal killing machines. This process can take place as long as a Skitarius possesses a head, torso, and some limb-stumps.

Heavily modified for their scouting missions, almost their entire human heads have been replaced with a specialized domed helm allowing a three-hundred and sixty degree view of the battlefield. They are equipped with a wide array of weapons including Stubcarbines, Power Swords, Taser Goads, and Flechette Blasters.

Skitarii ProtectorEdit

Protectors were soldiers and guards that worked in the Adeptus Mechanicus.

They were genetically engineered and augmented Humans that wore red robes and bronze masks that showed green mechanical eyes. Members of the Protectors typically carried weapon staves and served as the personal guards within a techpriest's forge. They were noted to smell of spoiled, decayed meat and oils. skitarii protectors were much more commonly used during the horus heresy and most were deemed ineffective by the martian priesthood and the use of thousands of tech thralls became more popular to defend forges and forgeworlds when the mechanicus was short on full blown skitarii. Which, in true Warhammer fashion, makes no sense as they are made in the same way and Protectors, being actual Skitarii, would have been far more effective and just as numerous as Tech-Thralls (due to being made in the same way as the thralls). Dammit, GW!


Secutarii are the protectors and recoverers of Titans, and many are drawn from the service of normal skitarii from the Exploratory Fleets who show great affinity working with Titans. Their own article explains them more in depth.

Serberys Sulphurhounds/RaidersEdit
