What Are Skitarii?
Skitarii are the cybernetic foot soldiers of the Adeptus Mechanicus, the tech-priesthood of the Imperium. They form the backbone of almost every Mechanicus army, both in the lore and on the tabletop. Where Space Marines fight for the Emperor and Guardsmen fight for their homeworld, Skitarii fight for the Omnissiah, the Machine God worshipped by the Adeptus Mechanicus.
Every Skitarius is a heavily augmented human. So much of their body has been replaced with cybernetics that they’re barely human any more. Their legs are mechanical, their senses are enhanced with optical implants and data-tethers, and their minds are conditioned to feel nothing but devotion to the machine. They don’t fight with courage; they fight with cold, calculated precision, directed by their Tech-Priest masters through noospheric data-links.
On the tabletop, Skitarii come in two flavours: Skitarii Rangers and Skitarii Vanguard. Both are built from the same kit, giving you flexibility in how you assemble your army. Knowing when to use each is one of the keys to playing Adeptus Mechanicus well.
Skitarii Lore
The Skitarii have served the Mechanicus since long before the Imperium existed. During the Age of Strife, the forge worlds raised their own armies to defend their precious technology from raiders and xenos. These soldiers were augmented with whatever technology was available, crude bionics at first, then increasingly sophisticated cybernetics as the forge worlds consolidated their power.
When the Emperor forged the Treaty of Olympus with Mars, the Skitarii became part of the Imperium’s war machine. But they answer to the Tech-Priests, not to Imperial commanders. Each forge world maintains its own Skitarii Legions, and their maniples are deployed wherever the Mechanicus needs them: defending forge worlds, accompanying Explorator fleets searching for lost technology, or joining Imperial crusades.
What makes Skitarii disturbing is how they’re made. They don’t volunteer. The Tech-Priests take candidates from the populations of the forge worlds and subject them to extensive surgical modification. Their free will is suppressed by neural implants and replaced with combat protocols and unwavering obedience. They feel no fear, no doubt and no mercy. They are tools of the Omnissiah, as much machine as the weapons they carry.
The Skitarii Alpha, the sergeant-equivalent, retains a little more autonomy than the rank and file and can make tactical decisions in the field. But even an Alpha is ultimately guided by data from the controlling Tech-Priest through the noosphere, the Mechanicus’s equivalent of a wireless network.
Skitarii Rangers vs Vanguard
The two Skitarii variants serve distinctly different roles, and understanding the difference is critical for building an effective Adeptus Mechanicus list.
Skitarii Rangers
Rangers are the long-range specialists. Armed with galvanic rifles, they sit back on objectives and pour accurate fire into targets at range. Their job is to hold ground, screen more valuable units and add steady firepower from a safe distance.
Rangers excel at:
- Holding backfield objectives
- Providing consistent long-range shooting
- Screening against deep strikers
- Taking out light to medium infantry at range
Skitarii Vanguard
Vanguard are the aggressive close-range option. Armed with radium carbines, they advance up the board and saturate enemies with irradiated rounds. Their weapons put out more shots at shorter range, making them ideal for pushing forward and contesting mid-board objectives. Their radiation also saps the Objective Control of non-vehicle enemy units close by, making them a nasty unit to stand next to on an objective.
Vanguard excel at:
- Pushing onto mid-board objectives
- High-volume short-range firepower
- Aggressive screening and board control
- Punishing units that get too close
Which Should You Take?
Most Adeptus Mechanicus lists run a mix of both: Rangers hold the backfield while Vanguard push forward. If you can only pick one, think about your army’s plan. If it’s vehicle-heavy and needs cheap objective holders, take Rangers. If you need bodies pushing up the board alongside your Ironstriders and Kastelans, take Vanguard.
Skitarii on the Tabletop
Rangers and Vanguard share the same basic profile: fragile, lightly armoured infantry with one wound each, protected by a 5+ invulnerable save, and with good Objective Control for their cost. They come in squads of ten, led by an Alpha who can take an upgraded melee weapon or a pistol. The difference between the two units is almost entirely in their guns and their special abilities.
For exact stats, points and abilities, always check the current Adeptus Mechanicus codex, the Munitorum Field Manual or the Warhammer 40,000 app, as they are updated regularly. In 11th Edition, the Adeptus Mechanicus codex stays valid until the faction gets its 11th Edition book.
Weapon Loadouts
The Skitarii kit offers several weapon options beyond the standard rifles. Choosing the right loadout depends on what you need the unit to do.
Galvanic Rifle (Rangers Default)
The galvanic rifle is a long-ranged rifle that fires two shots per model. It has no armour penetration of its own, so it works best against light infantry. It represents the Mechanicus’s mastery of precision weaponry, and for Rangers sitting on objectives it’s reliable against most infantry targets.
Radium Carbine (Vanguard Default)
Radium carbines trade range for volume of fire. They spray irradiated rounds that are as dangerous to the environment as they are to the enemy, and put out more shots per model than galvanic rifles, making Vanguard deadly at close range through sheer weight of fire.
Arc Rifle (Special Weapon)
The arc rifle is an anti-vehicle special weapon. It fires crackling arcs of electricity that overload the machine spirits and systems of enemy vehicles, so it’s much more effective against vehicles than against infantry. If you’re facing vehicle-heavy armies, arc rifles give your Skitarii some anti-armour punch.
Transuranic Arquebus (Special Weapon)
The transuranic arquebus is a long-range sniper weapon capable of picking out characters and punching through heavy armour. It’s designed to be fired from a stationary position, which makes it a natural fit for Rangers sitting still on a backfield objective. Park them in terrain, don’t move far, and let the arquebus pick off priority targets.
Plasma Caliver (Special Weapon)
The plasma caliver is a more general-purpose special weapon that works against elite infantry and light vehicles alike. It’s a good choice when you don’t know what you’ll be facing.
Alpha Weapons
The kit gives the Skitarii Alpha options like an arc pistol, a radium pistol, a power weapon, a taser goad or an arc maul. On the current datasheet these are simplified: the Alpha can take an Alpha combat weapon and can swap their rifle or carbine for a Mechanicus pistol, so build whichever look you like. In most cases the melee upgrade is cheap insurance: it gives the Alpha a fighting chance if the squad gets charged.
Tactics
Playing Skitarii well means understanding their role within the wider Adeptus Mechanicus army.
Objective Play
Skitarii are your main objective holders. In 11th Edition, objectives are terrain areas rather than markers, and you control one by having more Objective Control inside the area at the end of a phase. A ten-model Skitarii squad brings plenty of OC for its cost. Use Rangers on backfield objectives where their range matters, and Vanguard on mid-board objectives where their close-range firepower punishes anyone contesting.
Screening
Spread your Skitarii out to screen against deep strikers and stop enemies landing behind your valuable units. In 11th Edition, reserves must arrive more than 8″ horizontally from all enemy units, so a well-placed squad can deny a big chunk of the board. Remember that reserves can’t arrive in battle round 1, so your screens matter most from round 2 onwards.
Don’t Overinvest
Skitarii are cheap infantry. Don’t sink too many points into upgrades. Their job is to hold objectives, screen and contribute some shooting. Your heavy lifting should come from other units such as Ironstriders, Kastelan Robots and Onager Dunecrawlers. Keep your Skitarii efficient and numerous.
Use Terrain
With light armour and one wound per model, Skitarii die quickly in the open. In 11th Edition, Infantry in a terrain area gain the benefit of cover, which worsens the attacker’s Ballistic Skill by 1, and Infantry in terrain that haven’t shot this turn or last turn can only be seen from within 15″. Use ruins aggressively, and position Skitarii where they can shoot without being easily targeted. A Ranger squad with a transuranic arquebus in a ruin is a persistent threat that’s hard to remove without committing real resources.
Doctrina Imperatives
Doctrina Imperatives are the Adeptus Mechanicus army rule, representing the Tech-Priests uploading new combat protocols to their soldiers mid-battle. Rather than the old system of trading Weapon Skill for Ballistic Skill, the current version gives your army a choice between a more defensive, hold-the-line posture and a more aggressive, push-forward posture, and you switch between them as the battle develops.
The exact effects are set by the current codex and can change with balance updates, so check the codex or the app rather than relying on older guides. As a rule of thumb for Skitarii:
- Use the defensive posture while your Rangers are holding backfield objectives and your opponent is closing in.
- Switch to the aggressive posture on the turn your Vanguard and other forward units push into the enemy’s half of the board.
- Remember that only one Stratagem can affect a unit per phase in 11th Edition, so the army rule is often your most reliable buff.
Synergies with Tech-Priests
Skitarii become noticeably better when led by the right characters. In 11th Edition, Leader and Support characters are attached when you write your army roster, and each bodyguard unit can take one Leader and one Support. Check each character’s datasheet for which units it can join.
Skitarii Marshal
The Skitarii Marshal is the dedicated field commander for Skitarii squads, improving their effectiveness in battle. If you’re running several Skitarii squads, a Marshal is a natural choice. He joins Rangers and Vanguard as a Support character rather than a Leader, so he can sit in the same squad as a Tech-Priest Leader. Attach him to your most important squad, typically the one holding your home objective or the one carrying special weapons.
Tech-Priest Dominus
The Dominus is a high-ranking Tech-Priest and a strong all-round leader, adding his own considerable firepower and support abilities to the squad he joins. He pairs well with a large Ranger squad sitting on an important objective.
Tech-Priest Manipulus
The Manipulus is a Tech-Priest who specialises in manipulating the energy fields around his troops, boosting the shooting of the unit he leads. He’s especially useful with Vanguard, helping them contribute while they advance up the board.
Supporting Units
Sydonian Skatros
The Sydonian Skatros is not a character but a scout walker unit: a single Skitarius mounted on a long-legged Sydonian walker, built to range ahead of the army. It suits a forward scouting role, grabbing early position ahead of the army, rather than a front-line fighting role. It makes a good companion to Ranger squads holding the flanks.
Frequently Asked Questions
Are Skitarii Rangers or Vanguard better?
Neither is strictly better; they fill different roles. Rangers are better for holding backfield objectives and long-range shooting. Vanguard are better for pushing forward and close-range engagements. Most armies benefit from taking both.
How many Skitarii should I take in a 2000-point army?
Typically two or three squads of Skitarii form the backbone of an Adeptus Mechanicus army. This gives you enough bodies to hold objectives while leaving points for your more powerful units. Some lists run more if they want a large infantry presence.
Can Skitarii fight in melee?
Technically yes, but poorly. They have weak melee skills and weapons (aside from Alpha upgrades), and only one wound each. Avoid melee whenever possible. If you’re charged, fight back, but don’t plan around Skitarii melee combat.
Are Skitarii good in 11th Edition?
Skitarii remain the core infantry of any Adeptus Mechanicus army, and 11th Edition’s terrain-based objectives and cover rules suit cheap infantry that can sit inside ruins. How strong they are at any moment depends on points and the current balance state, so check recent results and the latest Munitorum Field Manual for an up-to-date picture.
What’s the best special weapon for Skitarii?
The transuranic arquebus is best for Rangers holding a static position, thanks to its range and precision. Arc rifles are best for Vanguard pushing forward, as they add anti-vehicle punch to a unit already closing with the enemy. Take the weapon that matches the squad’s role.
What is the difference between Skitarii and Tech-Priests?
Skitarii are the soldiers of the Adeptus Mechanicus, heavily augmented warriors who fight under orders, while Tech-Priests are the priesthood that rules it. Tech-Priests study and maintain technology in the name of the Omnissiah and command Skitarii through the noosphere. On the tabletop, Skitarii are the core infantry, and Tech-Priests such as the Dominus and Manipulus are characters that support them.
What are the Skitarii ranks?
The basic soldier is a Skitarius, and each squad is led by an Alpha, the sergeant-equivalent with a little more autonomy. Squads are grouped into maniples, maniples into cohorts and cohorts into a forge world’s Skitarii Legion. Skitarii Marshals lead in the field, and the whole force answers to the Tech-Priests, from a Dominus up to the Magi of the forge world.
What Skitarii units are there?
The Skitarii line covers Skitarii Rangers and Vanguard, the Sicarian Ruststalkers and Infiltrators, and the Skitarii Marshal. They also field the Ironstrider Ballistarii and Sydonian Dragoons walkers, the Serberys Raiders and Sulphurhounds cavalry, the Pteraxii Skystalkers and Sterylizors jump infantry, and the Sydonian Skatros scout walker. Rangers and Vanguard are the core troops covered in this guide.
Which forge worlds do Skitarii come from?
Every forge world raises its own Skitarii Legions, each with its own colours. Mars is the most famous and the seat of the Fabricator General, and other well-known forge worlds include Lucius, Agripinaa, Stygies VIII, Graia, Ryza and Metalica. Each has its own character, such as Ryza’s mastery of plasma or Metalica’s ear-splitting war-hymns, so players pick a forge world to suit the look and theme they want.
