Commanders of elite kill teams know that victory is often a matter of securing the proper resources and ensuring their operatives have the tools they need to get the job done. Given the critical nature of their missions, kill teams often find themselves equipped with all manner of useful tools, from measuring devices to portable barricades.

Amongst the storied regiments of Cadia, the Kasrkin are lauded as the elite of the elite. These special operatives are trusted with more potent weaponry, such as high-powered hot-shot lasguns, and equipped with thicker carapace armour than their peers. The Kasrkin are peerless shots and battle-tested killers – disciplined and professional, they are equal or superior to any unaugmented warrior of the Imperium.

Inquisitors wield nearly limitless power in the Imperium, and dispatch cells of sanctioned agents across the galaxy to do their bidding. Led by trusted Interrogator apprentices, these secret teams might include customised servitors, soldiers seconded from any and every military branch, dangerous psykers, convicted killers with skills too ‘useful’ to waste, and religious zealots whose fervour shields them from experiences that would drive more rational souls into madness.

Imperial Navy Breachers are the elite fighting troops of the Imperium's many naval assets, from orbital stations to mighty battleships – aggressive blunt instruments instructed extensively in close-quarter fighting techniques. Well-equipped and experienced in hazardous boarding actions, these squads are clad in fully-enclosed void armour, with mag-boots and rebreathers for zero gravity operatioons, and given access to specialised equipment designed for cracking enemy bulkheads.

Hierotek Circles of the Necron dynasties operate in secret throughout the stars, cold-hearted coteries of android killers acting in service to obsessive Cryptek masters. These ancient Necron techno-sages are driven by ruthless paranoia and amoral curiosity, issuing missions to their underlings according to labyrinthine plans that few outside of their own kind can understand. The Hierotek Circles employ eldritch science and specialist constructs to overwhelm all opposition, completing their clandestine missions with frightening thoroughness.

Hearthkyn Salvagers are experienced combat-surveyors of the Leagues of Votann, deployed to scout out hazardous locations such as drifting space hulks and rad-blasted killzones in search of wealth and resources. Loaded with advanced equipment for scanning and navigating their dangerous surroundings, these doughty explorers use bursts of intense firepower to eliminate anyone obstructing their search.

Archons are the rulers of the Dark City's Kabals, callous Drukhari schemers driven by boundless avarice. When these cartel-masters require precision and certainty, they assemble their Hand – an elite team of Kabalite experts, chosen for their terrifying skills in everything from poison to bladework. Hands of the Archon accomplish their employer's dark whims without fail – all while jockeying for influence and prestige in the courts of Commorragh.

Foul warbands afflicted by a gruesome techno-organic plague, the Gellerpox Infected are nightmarish meldings of festering flesh and malignant machinery. These hideous beings may once have been loyal servants of the God-Emperor, plying the void beneath the safety of a geller field – such days are long gone, wiped away by supernatural sickness and a gleeful compulsion to spread their infection across the stars.

Beastmen are an abhuman subspecies, condemned across the Imperium as unclean mutants. Embittered by their persecution, many Beastmen turn to the Ruinous Powers, congregating on the outskirts of civilisation in savage herds dominated by Fellgor Ravagers. These brutal Beastmen are veterans of countless raids, who prove their strength and devotion to the Dark Gods through braying war cries, swift slaughter, and violent sacrifices.

Kroot Farstalkers are experienced explorers and savvy mercenaries, roaming the galaxy in search of exotic prey and plunder. Farstalker Kinbands act as scouts for wandering Kroot Warsphere ships, seeking out fresh employers and profitable warzones under the command of a skilled Kill-broker – equal parts wily negotiator and keen tactician. Armed with sturdy hunting weapons and strange alien weaponry – taken as loot and payment alike – these stealthy gene-hunters stalk the battlefield, springing deadly ambushes to bring in a worthy bounty.

The Adeptus Arbites enforce the Imperium's laws without exception or mercy. Exaction Squads are formed of only the most experienced Arbitrators, called into service to hunt down dangerous transgressors for interrogation and punishment, no matter where they hide. They do not hesitate to crush any who stand in their way, ruthlessly bludgeoning or cutting them down in blazes of firepower, never halting until their target is in custody.
