Lightning claws, power fists, and jump packs—the Ursarax Cohort is ready to tear through enemies in Horus Heresy; see how they bring Mechanicum melee power!
The Mechanicum never does subtle, and the Ursarax Cohort is no exception. These brutal cyborg shock troops come packed with lightning claws, power fists, and oversized jump packs, making them a high-speed nightmare for anything in their path. Built for relentless close combat, they trade the Thallax’s ranged firepower for raw melee destruction.
With the new plastic kit bringing these war constructs to the tabletop, it’s time to see how they fit into a Horus Heresy army. Whether it’s tearing through elite infantry or smashing armored targets, Ursarax are here to hit hard, move fast, and leave wreckage behind. Let’s break down what makes them a must-have for any Mechanicum force.
Cyborg Shock Troops Land in Horus Heresy
The Mechanicum never stops finding new ways to unleash devastation, and this time, they’ve cooked up something truly terrifying—the Ursarax Cohort. If you thought the Thallax were unsettling, these cybernetic wrecking balls take it a step further, swapping out long-range firepower for brutal, up-close destruction.
What is the Ursarax Cohort?
Imagine the Thallax but angrier, faster, and more specialized for close combat. The Ursarax were the brainchild of Explorator Magos Enabrin Falkan, an independent mind who needed a unit that could hit hard and fast. By fusing existing Mechanicum tech with oversized jump engines, he created these brutal shock troops—living weapons designed for raw aggression.
They come equipped with Utan jump boosters, which launch them into the fray, where they rip apart enemies with lightning claws and power fists. If that wasn’t enough, some carry volkite incinerators, adding extra firepower to their already devastating toolkit.
Unlike soulless servitors, the Ursarax retain enough consciousness to make battlefield decisions. The catch? Their existence is a non-stop cycle of agony, only relieved when they complete objectives and earn a fleeting moment of neural anesthesia. Grimdark enough for you?
How Do They Fit into a Horus Heresy Army?
Mechanicum armies already pack some of the nastiest units in The Horus Heresy, and the Ursarax fill a unique role as mobile melee brawlers. If you need something faster than Thallax but deadlier in close quarters, they’re an excellent addition.
Strengths:
Speed & Mobility – Their jump boosters let them reposition quickly and pounce on vulnerable targets.
lose Combat Monsters – Lightning claws and power fists make them a threat to both infantry and heavier units.
Durability – Like Thallax, they’re tough and won’t go down easily.
Weaknesses:
No Long-Range Options – Unlike Thallax, they lack strong ranged capabilities.
Vulnerable to Massed Fire – Despite their resilience, focused fire can bring them down before they reach combat.
If you’re playing a Mechanicum force that likes to control the battlefield through aggressive maneuvers, Ursarax brings the pain where it matters most.
The Plastic Kit: What’s in the “Box”?
The upcoming plastic Ursarax kit is set to include six models, armed with lightning claws and volkite incinerators. For those who prefer even more brute force, two of them can swap their claws for power fists.
This marks a big step forward for Mechanicum players who’ve been waiting for more plastic options. Resin (and Forge World Kits) is great for collectors, but plastic kits make it easier to field larger squads without breaking the bank.
Final Thoughts On the Ursarax Cohort
The Mechanicum already boasts some of the most terrifying units in The Horus Heresy, and the Ursarax take that to another level. They add a highly mobile close-combat option that can pressure enemy backlines, punch through elite infantry, and create chaos in the right hands.
With a new plastic kit on the horizon, there’s never been a better time to add these brutal cyborgs to your collection. Whether you’re running a Taghmata Omnissiah, an Ordo Reductor, or just love the idea of launching pain-fueled killing machines into battle, Ursarax are ready to charge in—literally.
