Eradication Cohort: The 11th-Edition AdMech Skitarii Aggression Detachment

It is short, and it is entirely parasitic on the army rule. Each time a model in a Skitarii unit from your army makes an attack:

• If the Protector Imperative is active for that unit, re-roll a Hit roll of 1.
• If the Conqueror Imperative is active for that unit, re-roll a Wound roll of 1.

So the detachment does nothing on its own and everything once you decide which Imperative a unit is running. The interesting consequence is that anything granting both Imperatives at once grants both re-rolls at once, which is exactly what the Omnicogitator enhancement does, and it is why that enhancement is the first thing most Eradication lists buy.

Note the keyword: Skitarii, not Adeptus Mechanicus. That is a wide net (Rangers, Vanguard, Hastarii, Sicarians, Pteraxii, Serberys, the Skorpius chassis, Ironstriders, Dunecrawlers) but it excludes the Cult Mechanicus half of the faction entirely.

Six, all 1CP, all pointed forward.

• Unshackled Wrath (Shooting) — a Skitarii unit that has not shot gains Sustained Hits 1 or Lethal Hits, or, if you gamble, all of Sustained Hits 1, Lethal Hits and Hazardous. The big damage spike, with a real cost.
• Threat-cogitation Targeters (Shooting) — a Skitarii Vehicle unit re-rolls the Damage roll against Monsters and Vehicles. The anti-armour button.
• Precision Onslaught (Charge) — after a Sicarian unit declares a charge, roll a D6 per model in Engagement Range with a chosen target: each 4+ is a mortal wound.
• Servo-driven Charge (Fight) — an AdMech unit that has not fought gains Lance on its melee weapons.
• Unrelenting Aggression (Movement) — an AdMech unit that Fell Back can shoot, and a Skitarii unit can shoot and declare a charge. This is how the detachment refuses to be tarpitted.
• Analytic Reprisals (opponent's Shooting) — a Skitarii Infantry unit that lost models shoots back at the attacker.

• Omnicogitator — Skitarii Marshal only: both Imperatives active for the bearer's unit, which turns the detachment rule into a full set of 1-re-rolls on both hit and wound for that brick. The keystone enhancement.
• Belicosa-class Capacitor Vanes — AdMech model only: +6\" Range and +1 Strength on the unit's ranged weapons. Range plus Strength is a bigger swing than it looks on a mid-strength volume-fire army.
• Martial Signatum Amplificator — Tech-Priest only: models in the bearer's unit gain the Skitarii keyword, folding a Cult Mechanicus unit into the detachment rule.
• Omnissiah's Fury — Skitarii Marshal only: +2 Attacks and +1 Armour Penetration and Damage on the bearer's melee weapons.

(Points come from the Munitorum Field Manual and move with updates; confirm in the app.)

• Skitarii Rangers and Vanguard — the Battleline anchor. They are the re-roll engine and the reason nearby units get the good half of each Imperative.
• Sicarian Infiltrators and Ruststalkers — the only Sicarian datasheets, so they are the sole targets for Precision Onslaught's charge mortals.
• Hastarii Exterminators and Fusiliers — the pack's new Skitarii Infantry, and legal Analytic Reprisals targets.
• Skorpius Disintegrator — a Skitarii Vehicle, which is the specific keyword Threat-cogitation Targeters asks for.
• Skitarii Marshal — carries Omnicogitator or Omnissiah's Fury, and is now a Support character, so it can ride along with another Leader.

Take it when your collection is Skitarii-heavy and you want to play the aggressive, close-range version of the Machine Cult: advance into rapid-fire range, cash in the re-rolls, and follow up with Sicarian charges rather than sitting back on a gunline.

Be clear-eyed about the price. At 3 DP it fills your whole 2,000-point budget, and its rule is entirely conditional on the Imperatives, which means a turn where you need the wrong Imperative is a turn where half the detachment does nothing. Reviews around the pack's release rated it the weaker of the two 3-DP options, mostly because the same points spent on a 2-DP core plus Lords of the Forge buys more. Pick it for the Skitarii theme and the Omnicogitator brick rather than for pure optimisation.

Sample gameplan: deploy a Rangers or Vanguard block with a Skitarii Marshal carrying Omnicogitator so that brick runs both Imperatives and both re-rolls. Advance under Conqueror for Assault weapons, keeping everything inside 6\" of Battleline so the +1 Armour Penetration clause stays live. Spend Unshackled Wrath on the key volley, Threat-cogitation Targeters into an enemy tank, and charge with Sicarians using Precision Onslaught. Use Unrelenting Aggression to break out of a bad melee without losing the turn, and Analytic Reprisals to punish anyone who shoots your line.
