Power Armour

Power Armour is an advanced form of powered combat armour, worn primarily by the Space Marines and the Chaos Space Marines, though suits have been created to be worn by mere mortals. It is a completely enclosed suit of combat armour composed of shaped Adamantium and Plasteel plates, encased in a Ceramite ablative layer.

Each suit possesses a full suite of life-support functions for operation in hostile environments, an automated medicae system to provide some level of first aid to a wounded wearer and a highly advanced and fully integrated tactical targeting and threat analysis system known as Auto-senses.

The suit would be heavy and cumbersome to wear but for the electrically-motivated fibre bundles within the armour that replicates the wearer's movement and enhances his strength beyond its already considerable superhuman baseline (for Space Marines). Whilst Power Armour is most commonly associated with the Space Marines of the Legiones Astartes, many organisations have also use powered armour of one sort or another, including but not limited to; the Emperor's own Custodians, Sisters of Silence and powerful or influential members of the ruling Imperial Elite.

Typically, however, these armours may not contain the same strength-enhancing properties or life-support functions of Space Marine Power Armour, nor do they always provide the same level of protection.

Design
The enclosing suits of armour worn by Space Marines are made from thick ceramite plates and would be cumbersome but for electrically motivated fibre bundles that replicate the movements of the wearer and supplement his strength. The last gene-seed organ to be implanted in a Space Marine -- the Black Carapace -- rests beneath the skin, itself fitted with neural sensors and transfusion ports.

These plug-in points mesh with Space Marine Power Armour, linking the wearer's nervous system to his suit's mind impulse controls, turning the suit into a second skin that moves with all the speed and precision of the Battle-Brother's own body. Without the Black Carapace, Space Marine Power Armour is almost useless, and it is therefore the most distinctive feature of a Space Marine and the true mark of an Astartes.

There are several patterns (or "marks") of Power Armour, whose appearances differ significantly. Many marks have special associations for certain legions and are often worn by their ceremonial Honour Guards or elite units, or may be entirely unique to a single legion all together. Power Armour is sometimes maintained by skilled Artificers who are not Space Marines, especially in the less mechanically inclined legions, but servants who spend their lives working for the Legion and their Chapter descendants, generations of their family's passing on the craft to their children through the ages. Especially talented Artificers are justly celebrated, and examples of their work highly prized.

Power Armour is fully sealed, isolating the wearer from the outside environment and protecting him from chemical and/or biological weapons and toxic atmospheres. It also commonly includes numerous auxiliary systems such as radio frequency communicators, auto-senses, etc. Space Marines go through an arduous process where they receive various biogenetically-engineered implants culminating with the implantation of the Black Carapace which allows the Astartes a direct and instinctual neural interface with his Power Armour, transforming it into effectively a second skin.

The advanced systems of Space Marine Power Armour also monitor the Astartes' biological functions, feeding the collected medical information to the wearer and, if necessary, to the Legions Apothecaries when he is wounded. The armour's backpack contains the suit's main power source -- a sub-atomic microfusion generator and a back-up solar power converter and 100 solar cell batteries to store the absorbed solar energy. The backpack also contains the armour's environmental and life support systems and additional movement stabiliser thrusters for low and zero-gravity combat.

Common Components of Space Marine Power Armour
All patterns of Adeptus Astartes Power Armour since the Mk2 suit possess the following components:


 * Helmet - The armoured reinforced headgear that protects an Astartes head.
 * Auto-senses - A Space Marine's helmet contains most of his armour's combat systems, all of which are referred to by one title -- Auto-senses. These include thought-activated comm-augers and audio-filters, targeting reticules and range finders, tactical displays and Auspex-links, and a host of other features that further enhance the Space Marine's already superhuman senses.
 * Photolenses - The photolenses are the reinforced eye guards in the helmet that protect the Space Marine from dazzling light bursts. They also allow him to see into the infrared and ultraviolet ranges, as well as enabling vision in low-light conditions.
 * Respirator Vox Grill - The Vox grill can amplify a Space Marine's battle cries to deafening volumes. It also contains a respirator to filter out toxins and can be shut off with a thought, drawing instead upon an internal oxygen supply.


 * Gorget - Part of the armour that protects the throat.
 * Pauldron - The auto-reactive shoulder guards are shaped to deflect as well as absorb incoming blows, these shoulder plates typically display Adeptus Astartes identification markings, including Chapter symbols, company and squad markings, as well as many other honour badges.
 * Gauntlet - The armoured glove that protects both the hand and the wrist.
 * Cuisses - The part of the armour that protects the thigh.
 * Plastron - The armoured chestplate that is designed to protect the suit's armoured power cables, and more importantly, the Astartes vital organs. It is typically adorned with the Imperial Aquila or the Imperialis honour for more veteran Space Marines.
 * Couter - Part of the armour that protects the elbow.
 * Vambrace - Part of the armour that protects the forearm.
 * Poleyn - Part of the armour that protects the knee.
 * Greaves - Part of the armour that protects the lower leg. The greaves incorporate gyroscopic stabilisers and power units that can magnetise the soles of the armour's boots for combat in zero-gravity or other unstable conditions.
 * Sabaton - The armoured boot that protects the foot.
 * Backpack Power Unit- The main power source for the suit of Power Armour is located in the suit's backpack. This highly-efficient sub-atomic microfusion reactor core provides the power for all internal systems. The suit does contain a reserve power supply and a back-up micro-solar panel array in case of emergencies.
 * Life Signs Monitor - Adeptus Astartes Power Armour contains a suite of life-support functions, including an auto-medicae equipped with various painkillers, combat stimulants and anti-venoms.
 * Temperature Regulator - Astartes Power Armour automatically maintains the Space Marine's temperature. Heat is provided by the power core and thermal build-up can be vented via the backpack's distinctive nozzles. As a result, a Space Marine can fight anywhere, in the cold vacuum of space or the raging heart of a volcano, without even noticing the change of temperature. This thermal waste can also be used for limited maneuvering in zero-gravity.


 * Nutrient Reservoir - Astartes Power Armour contains a self-replenishing, high-energy liquid food store that can sustain a Space Marine's metabolism without need for further nourishment. During battle, there is no need for a Space Marine to stop to eat or drink.

History and Development
Power Armour has been in use since before the Age of the Imperium, worn by the techno-barbarians that dominated Terra during the Age of Strife. It was also worn by the early genetically-engineered warriors that formed part of the Emperor's retinue during his unification of Terra towards the end of the Age of Strife in the 30th Millennium. In the armour's earliest incarnation, the suit was not fully sealed or life-supporting, this being unnecessary while its use was still confined solely to Terra. Over the history of the Imperium, Power Armour has developed into many different forms. Need, circumstances and the recovery of new materials and lost advanced technology, so-called archeotech, has shaped the armour's evolution.

It may be noted that there appears to be a steady improvement in engineering and design through the years. However this progress is not because of any particular invention or creativity. Rather, the changes were triggered by the gradual rediscovery of knowledge and materials from the Dark Age of Technology, as the Emperor's Great Crusade reconquered the galaxy.

Mark I Thunder Power Armour
The first Power Armour suit type used by the proto-Astartes Legions was not in fact designed for them, but merely retrofitted from the suit worn by the older cadre of genetically-augmented soldiers, the Thunder Warriors, and from them it gained its name as the “Mark I Thunder Power Armour”, though the name was assigned after the fact and at the time of its use the suit was simply called "Power Armour." It was developed from the powered combat armour worn by the techno-barbarians that plagued Terra near the end of the Age of Strife. It was used during the Emperor's campaign to retake and reunite the homeworld and its moon before the Great Crusade.

It was by no means unique to the first Space Marines -- in fact, the techno-barbarian warriors the Emperor fought during the conquest of Terra wore it too, and the Emperor's forces of genetically-enhanced warriors were wearing it even before the first true Space Marines were developed. However, because it was designed with fighting in a terrestrial environment in mind, it is not fully enclosed, with no means to support the wearer in a vacuum. Only the upper body is powered, due in part to the fact that during the Emperor's Conquest of Terra, ranged weapons were difficult to make due to technological constraints, and so a warrior's upper-body strength was his most important asset. This early armour was produced on a completely local basis. There was no standard design, individual suits varied heavily and their exact designs were often a matter of personal taste.

The main part of the armour is the massive powered torso which encloses the chest and arms. Coiled energy cables beneath the armour plating transmit energy from the power pack on the back to the arms, greatly increasing physical strength. Since the fighting on Terra during this period was primarily close-quarters, the strength of a warrior's chest and arms was of paramount importance. The legs of this armour are not powered at all, but are enclosed in tough padded breaches, though simple steel plates were sometimes also used. Although uncommon, the best-equipped warriors sometimes wore armoured greaves and armoured boots. However, this ancient suit of Power Armour was noticeably noisier than later models, perhaps due to the unpowered legs, making stealth operations nearly impossible in it.

Mark II Crusade Power Armour
Mark II Power Armour was developed towards the end of the Age of Strife and was used during the dawn of the Imperium by the Space Marines who carried out the Emperor's Great Crusade to reunite the lost colony worlds of Mankind in a new Imperium of Man. After the conquest of Luna by the Emperor's new armies of Space Marines and the peaceful unification with the Martian Mechanicum, the red planets factories were set to work constructing a new and far more advanced type of Power Armour purpose made for the Emperor's newborn Space Marines.

This armoured suit is commonly referred to as "Crusade Armour," since it was designed with the planned Great Crusade in mind. It was the first fully enclosed suit of Power Armour, making it suitable for the conquest of space and operations in a vacuum. It was designed as a fully enclosed suit with life-sustaining systems that now allowed the Astartes to fight in deep space and on alien worlds with hostile atmospheres or environments.

The armour was made up of microscopic circular armoured rings of ceramite fitted under and over each other, making this armour relatively tedious to repair. The larger armour plates composed of these microscopic rings were linked together to allow for a greater ease of movement and most of the power cabling for the suit was threaded inside the plating.

The backpack retained a similar shape to that of the Mark I suits but now contained advanced life support equipment such as air-scrubbing, fluid recycling and emergency medical first aid systems as well as the power supply for the armour. The helmet was initially set in a fixed position, but did allow the occupant to turn his head inside the suit. In time, this was altered with newer technology, allowing the wearer some level of mobility. The helmet also contained electronic sensory devices and miniaturised Cogitators (computers) that monitored the surrounding battlescape and fed visual and auditory signals directly to the Astartes' cerebral cortex through a neural feedback mechanism.

This further enhanced the Astartes' already superhuman sight and hearing, while at the same time dampening any blinding flashes or deafening explosions. These so-called "autosenses," as well as the other internal improvements, all became standard equipment in every subsequent pattern of Imperial Power Armour.

Though quieter than the Mark I, Crusade Armour is also not intended for stealth, though the sight of an Astartes wearing this armour draws every Space Marine's mind to the glory of the Great Crusade.

Mark III Iron Power Armour
As the Great Crusade reached the planets towards the core of the galaxy, some of the worlds encountered were the Squat homeworlds, which were not pleased to find themselves the object of a galactic conquest, Emperor of Mankind or no. The Squats' independent and stubborn nature along with the conditions of the fighting in the Squats' underground cities spurred the creation of this new armour type.

The Mark III was best suited for spacecraft boarding actions and combat in confined subterranean tunnel complexes with little cover. This armour was ideally used by Space Marines when cover was minimal and combat was a matter of a simple frontal assault. Because of this pattern of Power Armour's great strength, it became known as the "Iron Armour" or Armorum Ferrum in Imperial High Gothic.

The Mark III was never intended to replace the Mark II armour but instead was a specialised suit to provide heavier protection than the normal Mark II suit when fighting in conditions similar to that found on the Squat homeworlds, in mines, subterranean complexes or the tight corridors of a spacecraft. It has more frontal protection than the Mark II Armour, but the weight of the rear armour was lessened to compensate.

The suit uses a heavy armoured helmet with sloping plates designed to deflect shots to the left and right, thus inspiring its name as the Iron Pattern. The helmet inspired the Mark IV and VI helmet designs. The wedge-shaped helmet (designed to deflect incoming fire from the front) formed the basis for the later distinctive Beak helmet of the Mark VI Pattern.

Mark IV Maximus Power Armour
As the Great Crusade reached its climax and the Imperium reached its zenith in terms of technology and strength, the Space Marine Legions found their original suits of Mark II armour wearing out. While some Legions chose to continue local production and maintenance, the Mechanicum of Mars designed a new variant, which was to be called the Mark IV or Maximus Pattern since it was produced during the days of the Imperium's greatest glory, and at the time was the greatest Imperial Power Armour mark to date.

At the Mark IV stage of Power Armour development, Space Marine armour began to take on an appearance recognizable to that of contemporary Power Armour patterns, its primary change being the abandonment of the separate abutting plates of armour in favour of larger, inflexible armour casings incorporating flexible joints. This marginally reduced an Astartes' mobility but was far easier to produce and maintain, and the suit was actually lighter and provided its wearer with more overall mobility due to the lessened weight, while not reducing the actual level of protection the suit provided compared to its Mark II counterpart.

Technical secrets from the Dark Age of Technology recovered on newly conquered worlds during the Great Crusade allowed the Mechanicum of Mars to develop the more efficient mark of armour, improving the quality of protection and reducing the suit's weight at the same time. Improved armouring of the suit's power cables allowed the main arm and chest power supply cables to be safely relocated to the exterior of the armour, while the use of new materials reduced the size and number of cables.

The various systems contained within the suit's backpack were miniaturised and made more efficient, allowing the backpack to be smaller, lighter and to make use of an altered exhaust system that provided a shape much closer to that of the Mark VI and Mark VII patterns of armour in widespread use at the present time.

The Mark IV suit's helmet was a completely new design, the basic shape inspired by the sweeping front of the Mark III, but with a new neck piece that allowed for far more freedom of movement while still maintaining an environmental seal. This advancement represented the Artificers' increasing experience with neural connector gear and the new materials which flooded into the Martian workshops as the Great Crusade progressed.

Whilst standard patterns of armour were shared across the Space Marine Legions during the Great Crusade, variations on these templates surfaced in most of the Legions, though these were in truth little more than cosmetic changes dictated by local forge world or legion traditions.

Mark V Xenocide Power Armour
Though almost all of the legions were equipped with advanced power armour suits by the beginning of the Rangdan War, the deverstating conflict placed a strain upon the Imperium's supply lines, forcing many legions to improvise or repair what they had on hand when normally, warriors would have simply been assigned new wargear. Many legions had already taken to canabalising their armour parts, combining marks together into so called "Pariah" armour, but something more was required.

This suit of Power Armour was developed by Space Marine Artificers and Techmarines on both sides of the divide as a solution to the supply problems caused by the Rangdan War. It was manufactured from the most basic of materials, and it was easy to maintain. Almost all of its users used molecular bonding studs to hold the armour layers of plasteel and ceramite together, and these studs became a distinctive marker of this pattern of Power Armour.

In time, it became traditional for the studs to be found on the head, lower legs, and left shoulder plate of the armour. Since the highly advanced Mark IV suits became so difficult to maintain, the Mark V was defined by its flexibility, as it was capable of being repaired with either new or old materials, depending upon their availability.

In many cases, older, heavier power cabling was used, which created a weak point on the armour throughout the suit's composition. To deal with this problem, many Legions Techmarines reinforced these suits with an extra plate of ceramite fitted over the top of the original plates with molecular bonding studs, which as noted above were responsible for the armour's distinctive appearance.

Due to the sub-standard materials used in the construction of this armour variant, the Mark V had a tendency to overheat quickly, and many Space Marines had to endure substandard performance by turning down the power output of their backpack to prevent intolerable heat build-ups. The helmet appears to be an early version of the Mark VII helmet derived from a modification of the Mark IV helmet, although it is significantly more primitive in its design, likely being a dead end and abandoned design that now saw new life amongst the warriors of the legions.

Of all the legions, the Omnimarines were the most well known for using this style of armour, having possessed a facsimile of eventual MkV armour far before the Rangdan War, using it throughout the Great Crusade. The Angelis Noctem were also known for this style of armour, having utilised it since the legions near death at the Black Star Rift mere years before the start of that great conflict.

Mark VI Umbral Power Armour
This classic Power Armour variant was developed in the last years of the Great Crusade by the Mechanicum as an upgrade to the MkIV armour. It is characterized by the beak-like muzzle on the helmet and a molecular bonding studded auto-reactive shoulder plate on the left shoulder of the armour.

The Mark VI suit was intended to be extremely easy to repair and maintain by Space Marine Legions engaged in the constant warfare, and was built with dual technology circuits that allowed the easy replacement of rare or sophisticated parts with more common or basic alternatives with no degeneration in protection or performance. It also included new fail-safes such as duplicate power cabling. Most notable in the armour however was the large sensor bundle that gave the armour far greater tactical visibility across a battlefield, all contained within the conical beak like helmet the armour sported.

The left shoulder plate, which usually took the brunt of enemy fire, boasting molecular bonding studs so as to be more easily replaceable. The Mark VI Pattern of Power Armour is the lightest form of the technology and has gained a reputation among Space Marine Techmarines as having the smoothest fit between its moving parts, reducing noise and power consumption, leading to the armour quickly being adopted adopted for specialised use within the legions, especially amongst reconnaissance or infiltration units.

The finalised pattern of the Mark VI armour was named Umbral Armour in honour of Umbral Blades, who had been chosen as the test bed for the new design, and as such were given more suits than almost any other legion, the armour becoming synonymous with the IIIrd Legion, especially after the outbreak of the Great Secession, where warriors of the IIIrd Legion managed to secure nearly all examples of this suit, destroying the details on its manufactur, in essence denying it to the Mechanicum and the Loyalist Legions.

Other Imperial Power Armours
Although Power Armour is most closely associated with the Adeptus Astartes and their legion forebearers, it is also used by other institutions of the Imperium of man, such as the Sisters of Silence or the kastarian First.

However, the mortals who use Power Armour do not possess the Black Carapace gene-seed organ implant, and so cannot be directly linked to the suit's advanced movement enhancement and fire control systems in the way Space Marines are, which decreases the armour's effectiveness.

Some high-ranking members of the Adeptus Mechanicus, the Machine Cult, use Power Armour, Enginseers of the Astra Militarum use it to protect them from enemy fire as they tend to the Machine Spirits of the Imperial Guard's vehicles.

Terminator Armour
Tactical Dreadnought Armour, more often called Terminator Armour, is one of the strongest forms of personal Power Armour in existence and is the heaviest and most resilient model the Imperium of Man has to offer. It was developed for a mid-range of uses between the armoured chassis of a true Dreadnought and standard Power Armour. It is composed of a specially synthesized ceramite/plasteel alloy exoskeleton whose manufacture is now unknown to the Adeptus Mechanicus, with servo-assisted interfaces that link into the user's own neurological and muscular systems to enhance movement.

It is able to withstand tremendous punishment, and serves as a solid heavy-weapons platform in open-field combat. Due to its size, it is best deployed in close quarters such as the corridors of a starship, where the standard-issue Storm Bolter can be most effective.

Artificer Armour
Artificer Armour is the name given to individualised and heavily modified suits of Power Armour of many different patterns provided only to Space Marines who have proven themselves worthy of the honour, such as Chapter Masters, Company Captains, members of the Chapter or Legions Honour Guard, or particularly skilled Veterans.

Though Artificer Armour and Power Armour are similar in appearance, Artificer Armour is as far beyond standard Power Armour as Power Armour is beyond the Carapace Armour used by the soldiers of the Imperial Guard. Ingeniously designed damage control mechanisms and superdense materials allow most suits of Artificer Armour to offer a much greater degree of protection than standard Power Armour, even rivaling that offered by Terminator Armour in some cases. Artificer Armour cannot, however, make use of weapons as powerful as those available to Astartes in Terminator Armour.

A suit of Artificer Armour is an extremely valuable relic for a Space Marine Chapter, and even the legions of old could not readily make use of these suits on a grand scale. Many elements of the suit will have been replaced or repaired over the long years and its heraldry altered for each wearer, but it is still held to be the same suit of armour and so is venerated for its history.

Techmarines also wear a form of Artificer Armour. These suits are rarely as old and venerated as the others possessed by the Chapter, but are essentially suits of Power Armour that have been heavily modified and improved by several generations of Techmarines. Such suits usually contain a vast array of mechanical interfaces and built-in servo-tools to aid a Techmarine in his duties for the Chapter.

Noxim Pattern Artificer Armour
Uniquely amongst the Emperor’s Legions, the Angelis Noctem have some of their number march to war not in the stocky masculine form of a starard Astartes, but instead in a far more lithe form, one that closely mirrors Nocterra’s own physique as a female. Though they are still men, even Nocterra’s geneseed only working upon the male of the species, these elite warriors have used their powerful psionic abilities to alter their appearance in honour of the Dark Lady. Though this has given them a far sleeker appearance than a normal Astartes, this appearance is deceptive, the warriors being every bit as strong as their counterparts in the other legions.

Further emphasising this change is the Noxim-pattern Artificer armour such warriors are equipped with, forged within the Dark Fortress deep beneath the surface of Noxim itself by mindscrubbed servitors and sworn Mechanicum adepts, the secrecy ensuring few understand the inner workings of such armour.

Each suit is a work of art, similar in appearance to regular Power Armour, but in truth being as far beyond standard Power Armour as Power Armour is beyond the Carapace Armour used by the soldiers of the Imperial Army. Ingeniously designed damage control mechanisms and superdense materials allow for the Noxim-pattern to offer a much greater degree of protection than standard Power Armour, rivaling that offered by Terminator Armour without slowing the user at all, as well as being significantly lighter, allowing the drop legion to maintain the use of their beloved jetpacks.

While many officers of the legion have earnt the right to wear the Noxim-pattern Armour, it is most commonly seen amongst the very best of the Angelis Noctem, the Lunar Guard and later, the Blinded, the two elite formations universally wearing such armour, punishing Nocterra’s foes wherever they may find themselves, the armour marking them as daughters of Nocterra first, and sons of the Emperor second...

Lorica Thallax
The Lorica Thallax is a type of Power Armour worn by the Thallax and Ursarax troops of the Mechanicum. Unlike almost all other examples of power armour, the Lorica Thallax was permanently surgically bonded to the body of the wearer. It uses mechanical armatures to replace the primary limbs, and a compact Plasma Reactor core to generate power for the warriors weaponry. The armour is fused directly to the spinal cord and nervous system of the wearer, which marks them out as a warrior of the Mechanicum while simultaneously serving as a symbol of their eternal servitude to the Machine God.

Vratine Armour
When a Sister-aspirant of the Sisters of Silence takes her final oaths of duty and says the last words she will ever utter aloud in her lifetime, she is given her panoply of war: the Vratine Armour -- literally "the armour of the oath."

It is a subpattern of technologically-advanced battlegear which shares design elements with both the Power Armour of the Legiones Astartes and the silicate-mesh of Selenite void-mail, though unlike either of those famed armours, it is not -- at least without additional gearing -- fully environmentally sealed or designed for extended operations.

It does, however, provide formidable protection from ballistic impacts and directed energy weapons, and is tailored and forged uniquely to its intended wearer to allow for their complete freedom of movement and to augment their reaction speed.

Custodian Armour
The Custodians of the Adeptus Custodes, the bodyguard of the Emperor of Mankind, also wear Power Armour of a design created just for them during the days of the Great Crusade. The panoply of the Adeptus Custodes, known as Custodian Armour, represents the pinnacle of the armourer's art.

Far more sophisticated than production-model Space Marine Power Armour, it is fashioned with rare Auramite alloy such as that used for the armour the Emperor Himself wore in battle, rather than the standard ceramite used in all other forms of Imperial Power Armour.

Each suit is unique to the Custodian Guard who wears it, as it is customised to its user, a finely wrought suit of master-crafted battle-plate in the Custodes' traditional golden colour, each a work of art in its own right and highly individualised after the fact by its user. Custodian Armour is also fitted with arrays of proximity sensors and Refraction Field generators to further enhance its formidable defences.

Post-Imperial Reformation Power Armour
In the wake of the Great Secession and the peace that followed, the Secessionist legions now looked to new roles through which to serve the Imperium, now that war was but a distant memory. For many legions, this meant they required little in the way of power armour, being equipped with functional and generic power armour that advanced as the ages past, becoming sleeker and more ergonomic, though losing some of the brute strength of the Great Crusade era armours.

For other legions however, their new roles necessitated not merely the continued use of power armour, but the development of entierly new types of power armour, many all but unrecognisable from their Great Crusade counterparts.

The Angelis Noctem
This armour was far lighter than Great Crusade era warplate, barely a fraction of the mass, looking slight by comparison. However, this lessened weight did not indicate a lesser degree of protection, the armour nearly as strong as the older Mk4 armour. Alongside this reduced weight, hexagrammic warding runes, designed by Nocterra based off of her own tattoo’s, were worked into every layer of the suits, providing a degree of protection against psychic attacks far greater than standard armour. The armour also features fully integrated shock absorbers, similar to the Mantles High Altitude Drop Exoskeleton’s of the Great Crusade and grav-assisted jump packs, allowing the legion the power of true flight, before slamming into the ground at near terminal velocity, their enemies scattering before them, drop pods all but eliminated from their armouries.

However, for all the strength of the armour, it did have its downsides, cutbacks in certain areas to allow for the lighter and more agile suits, namely in the power supply. Rather than featuring an external power pack like other marks of armour, the new armour featured an internal generator, able to power the armour completely, but not for extended periods of time. Now, more than ever, the Angelis Noctem were a hit and run force, streaking into combat to strike down their foe before withdrawing once more. This suited their new targets perfectly, the legion rarely being called upon to fight in protracted fights.

Power Armour of the Chaos Legions
Just like the Imperium those legions who had survived within the Webway after the Great Secession and subsequently turned to the service of the Choas Gods soon saw a mass advance in power armour technology, free from the strictures of the Mechanicum, the limitations of realspace or the burden of a peace-time economy, these armours were hellishly effective, as the Imperium would learn to its peril at the closing of the 41st Millennium.
