Tactical Dreadnought Armour, more commonly known as Terminator Armour, is an advanced form of powered armour developed for close-quarters melee fighting done by Space Marine Terminators, for whom slaying power is more important than maneuverability. These suits are primarily utilised in situations where standard Space Marine Power Armour does not provide enough protection for a warrior. When battle calls for durability and protection over agility, it is to revered suits of Terminator Armour that the Space Marines turn. Massively thick armour plates and powerful servo-muscles drive these defensive shells, and only the best and bravest of a Space Marine Chapter may don this ancient and sacred battle-harness.
Terminator Armour is an incredibly durable suit comprising an outer shell of heavy-gauge ceramite plasteel composite plates, mounted on an adamantium exoskeleton with servo-assisted interfaces that integrate with an Astartes' own neurological and muscular systems to enhance movement. Its advanced composition allows the wearer to survive hits from firepower that could penetrate even the armour of a tank, and it is the heaviest combat armour in any Imperial arsenal, able to withstand tremendous punishment. Offensively, it provides the strength to maintain mobility while serving as a solid heavy-weapons platform in open-field combat.
The elite 1st Company of most Space Marine Chapters uses Terminator Armour extensively, and only those Astartes who earn the Crux Terminatus, a special badge of honour said to contain a fragment of the Power Armour worn by the Emperor of Mankind when he defeated Horus at the end of the Battle of Terra, are permitted to wear it. It is said that the Crux Terminatus behaves as a ward that augments the Terminator Armour itself, capable of turning aside blows that would threaten even a war engine.
Less frequently, high-ranking members of the Inquisition have been known to wear a form of Terminator Armour sized for an ordinary human occupant. Notably, members of the Ordo Malleus in particular have been known to favour suits of Terminator Armour. However, lacking the genetically-engineered subdermal Space Marine organ known as the Black Carapace, Inquisitors are unable to neurologically interface with the armour, and generally find its bulk much more cumbersome than a Space Marine does.
Amongst the Traitor Legions that still reside within the hellish realm known as the Eye of Terror, only aspiring Chaos Champions or Chaos Lords who stand in great favour to the Ruinous Powers wear Terminator Armour. So scarce is Terminator Armour among the Forces of Chaos that sometimes an Aspiring Champion can only claim a suit for himself by killing the current wearer, whether in ritual combat or by more devious means. Chaos Terminators will often act as the personal guard of such an esteemed Champion. Within a warband of Chaos Space Marines, Chaos Terminators enforce the will of their leader and take the first pick of the spoils of victory.
Space Marine Power Armour has a long and glorious history, having its origins in the long-forgotten time before the Emperor's unification of Mankind on Terra during the Unification Wars fought by his legions of gen-enhanced pseudo-Astartes, known as the Thunder Warriors. Nothing is known of this time, but it is speculated that the first suits of human-developed powered armour were worn by the techno-barbarians that fought alongside the Emperor as he battled to bring Terra under his rule during the Unification Wars of the 30th Millennium. Over time, these suits were refined and improved, becoming the earliest incarnations of fully enclosed Power Armour.
The first suits of Space Marine Power Armour were developed from this armour during the late 30th Millennium, and were said to have been worn by the first Space Marines of the Legiones Astartes as they launched the Great Crusade to reunite the worlds of the Solar System under the Emperor's control. Legends tell that once the Terran Solar System was secure, and the process of rebuilding firmly in hand, galactic conquest began in earnest. Faded techno-arcana of the Adeptus Mechanicus tell that even before the Age of Strife had ended, the Emperor had started to make provisions for his Great Crusade. Part of these plans included the re-equipping of the Space Marine Legions with a far more sophisticated fighting suit that Imperial historians have dubbed Mark II "Crusader" or "Crusader Armour". Alongside these developments, the Emperor initiated a programme to develop a system of armour that would provide even greater protection than that offered by Power Armour for Space Marine Legionaries on the field of battle.
The technology for Exo-armour was originally developed during Mankind's Dark Age of Technology. These sealed environment suits enabled maintenance crews of spacecraft to operate in extremely hazardous environments such as hard vacuum or in other adverse atmospheric conditions. Exo-armour was constructed from heavy gauge Plasteel plating, forming an armoured shell that could withstand even the colossal impact of high-speed orbital micro-debris. It is the only armour suitable for working inside the high-pressure casings of plasma reactor shields, or the extremely corrosive environments inside the holds of bulk chemical carriers. These same qualities, suitably enhanced, were used to make Tactical Dreadnought Armour virtually invulnerable to most weapons. The development of Terminator Armour, as Tactical Dreadnought Armour soon became known, was well underway during the Great Crusade to replace Power Armour, but was relegated to its current role due to a lack of maneuverability.
During the Great Crusade era, the Mechanicum was receiving a steady influx of new and rediscovered technologies from each planet brought to Imperial Compliance, and, in an effort to stem the horrendous loss of Astartes lives resulting from the ferocious conquests, attempted to design the "ultimate" pattern of Power Armour which would render a Space Marine virtually invunerable. The design emerged from a hybrid of standard Astartes Power Armour, the cybernetic shell of a Dreadnought and the armoured hostile environment suits long worn by Terran engineers who worked in difficult conditions like debris-plagued orbital space and the radioactive engine cores of interstellar spacecraft. Tactical Dreadnought Armour, as it was called, would turn the Astartes warrior within it into a living tank.
The eventual result of the Mechanicum's travails was only a partial success: the first suits of Terminator Armour did, as intended, afford a level of protection previously unattainable for its wearer. Like Power Armour, these suits were equipped with fibre-bundle synthetic muscles and imposed few movement restrictions upon the wearer despite their immense weight. But they were also too bulky, and their massive weight made running difficult despite built-in auto-balancers. The suits suffered from voracious power demands, and few existing armaments could be carried as the armour's sheer bulk made handling and reloading impossible. But most importantly, the sheer amounts of raw materials and manpower required to craft Terminator Armour were so great that retrofitting the whole of the existing Space Marine Legions with it was simply not feasible for the already thinly stretched logistics of the nascent Imperium of Man.
Several patterns of Terminator Armour evolved in parallel from the Forge Worlds of the Mechanicum and the armouries of the Space Marine Legions. The Mechanicum refined their concept, and developed weapons specially adapted for it, like Combi-weapons and the Reaper Autocannon. Terminator Armour was then presented in limited numbers to the crusading Legions, who quickly found a use for it. Massively armoured, sealed against any hostile environmental conditions and incorporating their own heavy ranged or close combat armament, Terminator Armour designs soon proved their worth.
Terminator Armour, with its ability to maximise the firepower and protection for a Space Marine, became standard on missions in extremely confined spaces like the corridors of a hive city, or during a boarding action on a Space Hulk where Dreadnoughts and armoured vehicles could not operate because they were too large to fit. Anecdotal evidence of this adaptability and willingness to embrace new weapons of warfare can be found in Horus' vocal backing of the Tactical Dreadnought Armour project, with the result being that his Luna Wolves Legion was one of the first and most widely equipped with Terminator Armour and at the forefront of the development of tactics for its use in assaults. By the time the Horus Heresy erupted and the Arch-traitor Horus first struck a blow against the Emperor during the Istvaan III Atrocity, these heavily armoured suits had become widely available to the Space Marine Legions.
According to fragmented records of the Adeptus Mechanicus, Terminator Armour was originally designed to be the ultimate Space Marine Power Armour, and was envisioned to replace the older suits. However, as the Horus Heresy devoured the Imperium's resources, and the Mechanicum divided into separate factions during the Schism of Mars, Terminator suits became increasingly rare, for they were exceptionally difficult to create and maintain. In addition, during most battles their bulk became a disadvantage against the lighter power-armoured warriors who easily outmanoeuvred them. These suits were highly sought after, and they were used to great effect in the countless bloody and short-ranged battles waged in cramped conditions, such as boarding actions in ship-to-ship engagements, hive cities and tunnel fighting. It is in these kinds of engagements that Terminator Armour excels, as it is under these conditions that their bulk and sturdy frame serves best.
Very few suits of this early Terminator Armour were ever manufactured by the Mechanicum before the Horus Heresy began, and the secrets of the technology's design have now almost been lost. As a result, every suit of Terminator Armour is treated as an irreplaceable, precious relic by the Space Marine Chapters that own them. In the late 41st Millennium it is a rare thing to see a "new" suit of Terminator Armour. If an additional suit is required, it is usually cobbled together from refurbished parts salvaged from the remains of Terminators killed in action. Indeed, as time marches onward, the knowledge of how to fabricate some of the more complex pieces of Terminator Armour has become only a desperate hope in the minds of the Tech-priests of the Adeptus Mechanicus, whose understanding of science and technology has been slowly decaying for the last 10,000 standard years.
Due to the amount of labour required and the difficulty of reproducing a single suit of Tactical Dreadnought Armour, this armour is only produced in extremely small numbers. There are dark rumours that Heretek Warpsmiths within the Eye of Terror may also possess some rare copies of the original STC blueprints, thus making it possible for them to reproduce new suits of Terminator Armour for the Chaos Space Marines of the Traitor Legions as well.
Terminator Armour Composition
Terminator Armour contains a full exo-skeleton and a complex arrangement of fibre-bundle muscles that allow a warrior to fight with deadly skill in close quarters, where agility is not of paramount importance. These incredibly durable suits are comprised of an outer shell of heavy-gauge ceramite and plasteel composite plates, mounted on an adamantium exoskeleton with servo-assisted interfaces that integrate with an Astartes' own neurological and muscular systems to enhance movement. Its advanced composition allows the wearer to survive hits from firepower that could penetrate tank armour, and it is the heaviest form of combat armour in any Imperial arsenal, able to withstand tremendous punishment. Offensively, it provides the strength to maintain mobility while serving as a solid heavy-weapons platform in open-field combat.
In the same manner as Power Armour, Terminator Armour contains its own independent power supply and fully enclosed life-support functions, though those incorporated in Terminator Armour are more powerful and longer-lasting. Various augers and auspex enable the Space Marine operator to be fully aware of his environment, both externally and internally, and to monitor such things as radiation levels, proximity of biological entities and the life signals of the body. These operate in the same way as the support systems in power armour, although several other devices have been added to improve the protective aspects even further. Teleport Homers enable the bearers to teleport into the midst of battle with a good degree of accuracy.
Meanwhile, threat detectors and motion sensors aid the Space Marine in avoiding enemy weapon emplacements and other situational dangers. In addition, the suit is fully equipped with a range of auto-senses and targeters, allowing the tracking of targets with the utmost accuracy. Terminators are linked to each other with pict-display units, allowing the Space Marines to see what their brother warriors see. All suits are capable of this, but to avoid confusion, it is usual for only the Sergeant's armour to broadcast pict-signals.
Terminator Armour Usage
A Chapter's elite 1st Company is known as the Veteran Company and contains its bravest and most heroic battle-brothers. Many of these Veteran Marines will have risen to the rank of Veteran Sergeant before being inducted, though less experienced Space Marines are often accepted into its ranks for performing acts of exceptional courage.
These Space Marines are mighty heroes whose legendary actions have become part of the Chapter's history, and it is every warrior's ambition to become one of their Chapter's elite. The 1st Company is invariably the most powerful company in the Chapter, as many of its warriors are trained to take to the field of battle wearing Terminator Armour. All Space Marine Chapters maintain a number of suits of the revered and rightly feared Terminator Armour, and these are amongst a Chapter's most prized relics.
Suits of Terminator Armour are rare and highly sought after, and as such, each Chapter carefully maintains the suits in its possession. Incredibly ancient, the secrets of their construction have long since been lost and each one is revered by the Space Marines and lovingly maintained by the Chapter's Techmarines. The armour is often ancient, and many of the older suits were produced before the Horus Heresy. Although new suits are manufactured by the Adeptus Mechanicus, the production rate is so slow and the demand for them so great that each Chapter takes the utmost care of its precious remaining suits. Each suit has a special place of honour within the 1st Company's Chapel and only warriors of the 1st Company and selected senior commanders may enter the armoury and don these holy artefacts. It requires rigorous training to be able to fight in Terminator Armour and, once trained in its use, a Space Marine will be expected to perform above and beyond his brethren, acting as an example to the rest of the Chapter.
Less frequently, high-ranking members of the Inquisition have been known to wear a form of Terminator Armour sized for an ordinary human occupant. Notably, members of the Ordo Malleus in particular have been known to prefer them because of their struggles with often physically-overpowering daemons. However, lacking the genetically-engineered subdermal Space Marine organ known as the Black Carapace, Inquisitors are unable to neurologically interface with the armour and generally find its bulk much more cumbersome than a Space Marine does.
Amongst the Veteran Marines of the elite 1st Company, each Terminator badge upon an Astartes' left shoulder guard is a special badge of honour made of stone, known as the Crux Terminatus and said to incorporate fragments of the Power Armour worn by the Emperor of Mankind when He defeated Horus at the end of the Battle of Terra. At the climax of the Horus Heresy, when the Emperor was mortally wounded following Horus' defeat, it is said that the Emperor decreed that His armour be taken off and melted down, and that the pieces be made into badges that all Terminators could wear in recognition of the service performed in the defeat of Horus. However, if this is true, then each suit of Terminator Armour must only contain the most miniscule of fragments. It is said that the Crux Terminatus behaves as a ward that augments the Terminator Armour itself, capable of turning aside blows that would threaten even a war engine.
Elements of the Crux Terminatus, on the shoulder plate of a Terminator, can be adorned with additional ornamentation in recognition of acts of supreme valour. One such adornment is the Crux Argentum, a shoulder badge of silver encrusted with gems that is awarded to Space Marines who perform acts of valour above and beyond the call of duty.
Almost all Space Marine Chapters maintain some suits of Terminator Armour and usually train their Veteran Astartes in their use, despite the armour's rarity. Terminator Armour is worn in very specific circumstances, such as when the close corridors of a hive city or Space Hulk need to be cleared. Astartes wearing normal Power Armour would not be ideal in such a role; instead, they would form a cordon around the Terminators while they carried out their search-and-destroy mission. In the present time, the 41st Millennium, Terminator Armour has become so rare that its use is reserved for those times when it will provide the maximal tactical benefit.
Terminators are best used during starship boarding actions where the cramped conditons and tight starship corridors maximise the effects of a Terminator's superior firepower while downplaying his lack of maneuverability, as the environment means flanking attacks are unlikely. Terminator Armour is also deployed into combat on standard battlefields when their heavy weapons can be used for long-range strikes, or they can use teleporter technology to suddenly appear amidst a vast group of enemies where their near-invulnerability to damage can transform them into true force multipliers with little risk of their own loss.
Squads of Terminators are most often employed in boarding actions or where the fighting is certain to be close and bloody. Although they can also be equipped with weaponry that allows them to fight at longer ranges, it is brutal assaults that they are primarily designed for. Terminator Armour is designed to carry a variety of weapon fits, but the most common armament is a Storm Bolter and Power Fist. This configuration allows a Terminator to engage the enemy at long range while advancing, before delivering a devastating assault with the deadly energies of a Power Fist -- a weapon capable of tearing through the hull of a battle tank with ease. Some Space Marines opt to carry a Chain Fist instead. These weapons have a similar to effect to Power Fists, but are equipped with an additional massively powerful Chainblade attachment that can carve through the armoured bulkheads of a mighty starship.
Within each squad, one Space Marine is often assigned a fire support role. The armour's massive fibre-bundle muscles and integrated suspensor fields allow a Terminator to carry a much heavier array of weaponry than his power-armoured brethren. Such warriors may carry the dreaded Assault Cannon to lay down a hail of heavy shells, a Heavy Flamer when the fighting is certain to be at extreme close quarters and the enemy closely packed, or a Cyclone Missile Launcher to engage heavily armoured targets at long range.
Certain squads of Terminators are also configured specially for close combat, with no ranged weaponry whatsoever. These squads are most often teleported into battle where the enemy cannot engage them with long-range firepower before the Terminators attack. The most favoured configuation for these squads is either a pair of Lightning Claws -- multiple, fist-mounted blades sheathed in lethal energy that can cut through armour and flesh with equal ease -- or a Thunder Hammer and a Storm Shield. This latter configuration is usually employed when the enemy is likely to make use of weaponry that may defeat even the formidable armour of a Terminator. A Storm Shield contains a small power field generator that can protect a warrior in melee and is proof against even the most lethal close combat weapons. The Thunder Hammer it is commonly paired with is a deadly weapon that releases a terrific blast of energy upon impact; those it does not kill, vehicles and the living alike, are rendered incapacitated.
Unlike Space Marines in Power Armour, Terminators are bulky and slow-moving. As a result, methods have been developed to allow the squads to reach the enemy in enough strength to prevail. Terminator Armour is designed to allow its wearer to utilise the technology of teleportation, and through this sometimes treacherous method of transport, Terminators may teleport right into the heart of the enemy battle lines. Although teleportation can be far from accurate, it is often the best way to get Terminators into the thick of the fighting quickly. Teleportation is a barely understood science, and the technology is far from perfect. Many Chapters of Space Marines -- such as the Space Wolves -- have a healthy distrust of such things and refuse to use it. For Chapters like this, the more common method of deployment for battle remains the more straightforward Land Raider Spartan heavy-assault transport. In this way, Space Marines in Terminator Armour can reach the heart of the battle in relative safety.
The Land Raider is one of, if not the most powerful tank in the Imperium's arsenal, able to withstand the impact of a Battle Cannon and barely be slowed. These tanks were designed primarily to enable Terminator Squads to travel in safety through the very worst warzones. They are equipped with frontal assault ramps that deliver the warriors within straight into the thick of the fighting. In addition, the most common pattern of Land Raider is armed with powerful Lascannons, and can act as mobile fire support for the Terminators once they have disembarked.
There are also many other Land Raider variants, but one of the most common is the Land Raider Crusader, a pattern developed by Marine-Artificer Simagus during the Jerulas Crusade of the Black Templars Chapter. This crusade involved the besiegement of many heavily fortified bastions of a Hive World and enabled the Sword Brethren Terminators of the Black Templars to penetrate the enemy lines with relative ease. With an increased transport capacity and weaponry designed to inflict maximum casualties amongst nearby infantry, many other Chapters quickly adopted this Land Raider pattern.
Another more recent development is the use of Storm Wing Squadrons. Comprised of a Stormraven Gunship and two Stormtalon escorts, these squadrons have proven exceptional in countless shock assaults. The superb manoeuvrability of a Stormraven twinned with its capacious transport bay is a potent combination -- so potent, in fact, that it is considered too valuable of an asset to be used lightly. Despite the variety of heavy armaments it boasts, the most deadly of the Storm Wing Squadron's weapons is the cargo it carries. Within the cabled belly of a Storm Wing Squadron's Stormraven is a squad of elite Battle-Brothers wearing Terminator Armour, waiting for their chance to charge forth to mete out vengeance to the enemies of the Imperium.
Because of the front-heavy design of the Stormtalon and the assault ramps that serve as its jaws, as soon as the aircraft settles upon its landing gear and its prow yawns wide, the unit inside can hurl themselves straight into combat, potentially changing the tide of battle within a few seconds of their arrival. So effective is the sudden onslaught of a Storm Wing Squadron that Traitors, heretics and xenos warriors alike have learnt to fear them, cowering at the triple silhouette and roaring afterburners of their approach.
Terminator Armour Variants
Designed during the Great Crusade and adapted from the heaviest of industrial gear, several types and patterns of Terminator Armour were developed concurrently. Tactical Dreadnought Armour has evolved over the centuries and each of the First Founding Legions has had their own deviation from the standard pattern Terminator Armours of the time. There are, according to fragmented Imperial sources, four other patterns of Terminator Armour in existence, but these have yet to be publicly outlined by the Adeptus Mechanicus. Some have been reported to be used by the Dark Angels, Ultramarines and Blood Angels Chapters, but they may or may not have been variants of the standard Indomitus Pattern. The different Terminator Armours that have seen service with the Legiones Astartes and the Adeptus Astartes since the founding of the Imperium of Man include:
- Cataphractii Pattern Tactical Dreadnought Armour - The Cataphractii Pattern of Terminator Armour was originally a prototype for the later patterns of Terminator Armour that was used by the Space Marine Legions and the warriors of the Legio Custodes throughout the Great Crusade and Horus Heresy eras. Whilst similar in many respects to the standard Indomitus Pattern Terminator Armour used by the Adeptus Astartes of the late 41st Millennium, it was set apart by a number of features such as the large, layered pauldrons, the pteruges protecting the elbow and thigh joints, and a helmet that resembled that used by the Mark III Iron Pattern suit of Power Armour. Although the use of the Cataphractii Pattern was rare before the Horus Heresy, some Legions, such as the Sons of Horus and the Iron Hands, possessed a large number of these suits. The Iron Hands Legion passed on these suits to their Successor Chapters during the Second Founding.
- Indomitus Pattern Tactical Dreadnought Armour - Originally designed during the Horus Heresy to replace the severe losses on both sides as the civil war dragged on, all of the Traitor Legions' Chaos Terminators now use Indomitus Pattern Terminator Armour, and it is also the pattern most commonly employed at present by the Adeptus Astartes because its template is held on many key Forge Worlds such as Mars. In the aftermath of the Horus Heresy, the Ultramarines pioneered the widespread use of Indomitus Pattern Terminator Armour as their Legion was unable to replace the older patterns of Terminator Armour after the loss of many important Forge Worlds during the war. Presently, only the Iron Hands, Minotaurs, and Salamanders Chapters do not have a full 1st Company's worth of Indomitus Pattern Terminator Armour for various reasons. The Iron Hands do not field Terminator Squads; only their officers wear Terminator Armour. The Minotaurs were granted their suits of Terminator Armour by the Inquisition; and the Salamanders encourage their elite Battle-Brothers to manufacture their own arms and armour, leaving their Techmarines free to construct and maintain older and more complex wargear.
- Gorgon Pattern Tactical Dreadnought Armour - A variant of Indomitus Pattern Tactical Dreadnought Armour devised by the Iron Hands Primarch Ferrus Manus and his Iron Fathers, this advanced prototype suit was just going into production at the outset of the Horus Heresy in the early 31st Millennium to supplement the Iron Hands Legion's combat-depleted stocks of Terminator Armour. The design replaced the field generators embedded in standard Indomitus Pattern Terminator Armour with experimental systems that converted incoming electromagnetic and kinetic energy into bursts of blinding light, able to incapacitate and maim nearby foes. The heat and electrochemical toxin bleed from the armour's systems limited the armour's agility, and its negative side effects required a high level of cybernetic rebuild for its wearer to endure. However, volunteers for this painful modification were plentiful in the Legion's ranks, many deeming it an honour to serve as part of this great endeavour.
- Tartaros Pattern Tactical Dreadnought Armour - Tartaros Pattern Terminator Armour was originally developed concurrently with several other patterns of Tactical Dreadnought Armour towards the closing years of the Great Crusade, and is still sometimes issued at present to the Veterans of a Space Marine Chapter’s elite 1st Company. Perhaps the most advanced form of Terminator Armour ever designed, the Tartaros Pattern shares many systems with the Mark IV Maximus Pattern of Power Armour, and provides greater mobility for its wearer than the Indomitus Pattern, with no loss in durability or protection. Of the shared characteristics between the Tartaros and Maximus Pattern armours, the most obvious is the helmet, though there are other more subtle ones such as the design of the armour on the back of the Tartaros' legs or the vambrace and gauntlets. The Tartaros Pattern also seems to share design characteristics with the Contemptor Dreadnought, most especially in the design of the torso plates. There are also characteristics inherited or derived from the venerable Cataphractii Pattern Terminator Armour, the pauldrons being the more obvious of these.
- Aegis Terminator Armour - The Aegis Terminator Armour used by the Space Marines of the Grey Knights Chapter is similar to the standard Indomitus Pattern Terminator Armour, but is inscribed with a complex network of protective prayers, runes and other wards which are psychically charged to provide better protection for a Grey Knight Astartes from the sorcerous powers of daemons and other servants of Chaos. The only major difference between Aegis Terminator Armour and the standard Indomitus Pattern besides the extra layer of psychic protection is the suit's helmet, which has been constructed to be very similar to that used by the ancient Mark III Iron Pattern suit of Power Armour.
- Chaos Terminator Armour - After the Traitor Legions were driven from the realms of Mankind into the Eye of Terror during the Great Scouring following the climactic end of the Horus Heresy, suits of Terminator Armour became even rarer. As each Legion of Chaos Space Marines fought one another for dominance in the endless internecine struggles for dominance or favour of their patron Chaos Gods, many of their most prized relics and artefacts of technology were lost due to attrition. As the Chaos Space Marines succumbed to powers of the Warp, much of the organisation and structure of their former Astartes Legion or Chapter has disappeared. Therefore, suits of Terminator Armour have become their most prized wargear - carefully maintained and guarded jealously by those fortunate few who have been in possession of these rare examples of advanced technology from a bygone era. Amongst the Traitor Legions that still reside within the hellish realms of the Eye, only aspiring Chaos Champions or Chaos Lords who stand in great favour to the Ruinous Powers wear Terminator Armour. So scarce is Terminator Armour that sometimes an Aspiring Champion can only claim a suit for himself by killing the current wearer, whether in ritual combat or by more devious means. Chaos Terminators will often act as the personal guard of such an esteemed Champion. Within the warband, they enforce the will of their leader and take the first pick of the spoils of victory.
