===Special units===
The VI Legion utilizes a variety of specialist troops, like every Legiones Astartes. Legion formations often include more Destroyers, Cybernetica Robots, and [[Terminator]]-suited units than other Legions. Death's Heads armoured units are largely made up of Sicarian-variant tanks and artillery vehicles. However, by the outset of the Heresy, many Predator tanks, especially Executioner-type, have made their way into VI Legion armouries. The Whirlwind has also gained widespread usage due to its ability to utilize various warheads. Legion aircraft usually consists of large, dual-role gunships that provide transport and ground support capabilities, most commonly the Fire Raptor, Storm Eagle, and Thunderhawk. Smaller, nimbler fighter craft, such as the Thunderbolt or, later, the Xiphon, are rarely used on the large-scale, often deployed exclusively as air superiority or escort craft.

Due to the low numbers of Astartes within the Legion, and their close ties with the [[Mechanicum]], large numbers of Cybernetica units have been inducted into the VI Legion, bearing their colours and heraldry, fighting under the watch of the Legion's Techmarines. These are most commonly Castellax, Domitar, or Vorax models, but logistical reports include several Arlatrax and even Thanatar-type units.

Amongst their more esoteric units are the Umbarax, designed with the Mechanicum of Orsus Secundus' aid, originally conceived as a test base for the Mashad Warhost's various weapons technologies. Originally based upon a mixture of Vorax-class Battle Automata and Thallax Tech-Thrall technolore, the Umbarax are based around a mortal host, their brain directly linked into a Cybernetica Cortex, allowing them to be used either autonomously or remotely. Most non-essential organs, such as the subject's skin, musculature, bones, and pain sensors, are removed and replaced by mechanical components within an armoured casement inside the unit's chest. Neural systems are hooked up to the various mechanical functions and actuations of the Automata suit, allowing the subject to easily control its systems once successfully implanted within the vessel. The subject is, unfortunately, largely cut off from outside stimuli, relying entirely upon sight and sound, greatly amplified by the unit's suite of tactical readouts, sensors, and cogitators. Umbarax units are primarily equipped with Radium or Phosphor weaponry, although Volkite, Irad, and even Phosphex weapons can be mounted. An Umbarax suit also includes a jump-thruster, a sensor suite, and a heads-up display referred to as a "Djinn-seer", allowing the unit to visualize and track personnel concealed behind any obstruction. They have been recorded as using a kind of distorted echolocation to perceive their targets more clearly.

Umbarax are deployed in a hunter-killer role, using their Djinn-seer and jump-thruster to track and eliminate opponents attempting to evade discovery. Although initial testing utilized mortal subjects, the VI Legion has adapted the Umbarax unit to recover Astartes, who have succumbed to gene-seed flaws shortly after their full induction into the Legion. The combination of the Djinn-seers sensor capabilities and an Astartes' natural post-human senses leads to an extremely perceptive if unstable, unit able to track a target for entire months without tiring. Once the Umbaraxi corner their quarry, they let loose their full destructive payload, destroying whomever they may come across. Rumour even has it that Umbarax units have been deployed across the wider galaxy, hunting enemies of the VI across the void.

Vandal squads are another specialized unit used by the VI Legion. The Vandals of Einchurt's homeworld were bands of warriors who had lost their original clan, forced to wander the rad-wastes in search of retribution and redemption. Within the VI Legion, an Astartes becomes a Vandal by failing to complete their assignment as efficiently and effectively as possible. While their numbers were never high before the Brotherwar, Legionnaires could be redeemed and thus return to their regular posts. However, even minor slights could result in one being inducted into the ranks of the Vandals.

By the end of the Great Crusade, Vandals take to the field in suits of Terminator Armour, almost entirely in Tartaros-pattern. They wield Volkite Chargers, War Flails, and the usual repertoire of heavy weapons. However, the most unique feature of the Vandal's equipment is their auto-loading Assault Harnesses. Unlike the more common Grenade Harness, an Assault Harness can be fired repeatedly, allowing the user to launch a blistering barrage of explosive projectiles. It is also connected to a store of various grenade types, commonly Phosphex, Ignis-Ferrum, and Rad, along with the standard Fragmentation.

Vandal squads are deployed on missions where extremely heavy resistance is expected. Siege, trench, and boarding warfare are their specialties, clearing points of contention with withering volleys of alchemical explosives. Enemies who attempt to flee are cut down by well-placed Volkite shots, and those who hold their ground must face the thundering charge of the Vandals.

The Primarch is often accompanied by his personal bodyguard, the elite Landsknetch. Clad in suits of Morventum Terminator Plate, a modified version of the standard Cataphractii Plate, they can wade through environments toxic enough to lay low even the scions of the Omnissiah or fully-clad Astartes. They wield heavy-headed power halberds of such a size even an Astartes in Terminator Armour requires both hands to effectively use it.
