Working in concert, armour and Astartes together become a weapon without equal.{{Fn|9}} Each suit of Space Marine Power Armour is a work of supreme artisanship, and although it may be one of many, each is a unique artifact whose spirit and history is of deep spiritual significance to both the [[Chapter]] to which it belongs and the Space Marine who wears it.{{Fn|9}} It can take decades to complete just one of the new Mk VII power armour, so it is often easier to make spare part for an existing suit than it is to make a completely new one.{{Fn|18}} There are numerous different Marks of Power Armour, most of which date back in terms of design and application many thousands of years ago to the time of the [[Great Crusade]] and the [[Horus Heresy]]. Each has its own lore and genesis in place and time. Even in the 41st Millennium some intact suits from this near-mythical age survive in active service as war-relics of the Chaos Space Marines. Countless others have been produced or reacquired since, and different Chapters often have entirely different panoplies they can call upon to armour individualise their forces. It is also far from uncommon for more recently fashioned armour to incorporate slivers or whole components from far older suits as revered connections to the past.{{Fn|9}} Space Marines go through an arduous process where they receive various implants culminating with the implantation of the [[Black Carapace]], which allows the Marine a direct and instinctual interface with the armour, making it in effect a second skin. The advanced systems of Space Marine power armour also monitor the Marine's biological functions, feeding the medical information to the Marine.{{Cite This}} ==='''Components'''===While Space Marine Armour has evolved and changed over the Millenniacrests, key components remain the same.{{Fn|15}}*'''Auto-senses''': Contained in the helmet, these systems include thought-activated communication arrays and audio filters, targeting reticules and range finders, tactical displays and auspex-linkshorns, skulls chains and a host of other features.*'''Photolenses''': Protect the Space Marine from light bursts and allow him to see in the infrared and ultraviolet spectrum's as well as enable vision in low-light conditions.*'''Respirator Vox Grill''': This thought-activated device amplifies a Marine's battlecry to deafening volumes and contains a respirator to filter out toxins and draw upon an internal oxygen supplyspikes.*'''Auto Responsive Shoulder Plates''': Shaped to deflect and absorb incoming blows, they usually display heraldry including Chapter, Company, and Squad symbols.*'''Chestpiece''': Designed to protect armoured power cables.*'''Backpack Power Unit''': This houses the primary power core for the armour, as well as reserve cells and an emergency solar collector.*'''Life Signs Monitor''': Regulate a suite of life support functions, including an injection system that can regulate painkillers, anti-toxins, and combat stimulants.*'''Nutrient Reservoir''': A self-replenishing high-energy food store that can sustain a Chaos Space Marine's metabolism.

When the Emperor began his conquest of EarthIt might sprout spines or bony ridges, the "[[Thunder Warriors]]", the proto-[[Space Marines]] which formed part of his retinue, were armoured in the same way as the soldiers of the other warlords. A thunderbolt and lightning symbol was displayed on the breastplate of warriors loyal to the Emperor - this was the personal badge of the Emperor be covered in those days, predating the Imperial [[Aquila]] which only became the symbol of the Imperium much later. The emblem gives the suit its common name – "Thunder Armour."{{Fn|1}} Thunder Armour was not an enclosing suit and offered no life support functions, being unnecessary while the fighting was confined to Terra and the similar environments of [[Luna]] and [[Mars]]. This early armour was produced on a completely local basis and as such individual suits varied heavily and their exact designs were often a matter layer of personal taste.{{Fn|1}} The main part of the armour is the massive powered torso which encloses the chest and arms. Coiled scales or flicker with coruscating energy cables beneath the armour plating transmit power from the power pack on the back to the arms, greatly increasing physical strength by a factor of between 3 and 4 times. Since 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 Mark are typically not power-armoured at all, but are enclosed in tough padded breeches. The best-equipped warriors sometimes wore armoured greaves and armoured boots, and such additional protection was common amongst the Thunder Warriors.{{Fn|1}} As with all powered armour, the power supply is contained with a notably bulky back-mounted unit, most of which is taken up by cooling systems designed to prevent the entire armour design from overheating.{{Fn|1}} Although it is very rarely used in the 41st Millennium, some suits of Thunder Armour are maintained for ceremonial purposes.{{Fn|1}} This ancient style of armour is noticeably noisier than later Marks. {{Fn|816}}

==Imperium='''Mark II "Crusade ====Sisters of Battle Power Armour"'''===*{{main|Sisters of Battle Power Armour}}The [[Sisters of Battle]] use a version of power armour designed for the [[human]] shape and size, known as Sororitas Power Armour. Sisters of Battle do not have the same [[Black Carapace]] as [[File:Mk2 crusade armor 200Space Marines]] do, as such some patterns of their power armour are not built with direct interface in mind, thus lacking the same benefits to strength and support systems integration.jpg{{Fn|thumb2a}} Other Sisters make use of armour that do benefit from direct connection via the usage of [[Imperial_bionics#Interface_Port|250pxInterface Ports]].{{Fn|Mark II Crusade Armour21}}{{Fn|60a25}}It is also known that some sisters, such as the [[Hospitaller]], make use of [[Imperial_bionics#Mind_Impulse_Unit| Mind Impulse units]], which may offer another avenue of controlling power armour.{{Fn|22}}{{Fn|19c}}

After the conquest of the main planets of the [[Sol system]], the factories on [[Mars]] were set to work constructing a new type of armour for the Emperor's elite [[Space Marines]]. This armoured suit is commonly referred to as "Crusade Armour," since it was designed with the planned [[Great Crusade]] in mind, and its production led to the Thunder ===Adeptus Custodes Power Armour being retroactively designated as the Mark I. It was the first fully enclosed power armour, with life-sustaining capabilities===*{{Fnmain|1}}, making it suitable for combat on toxic alien planets and the depths of space.{{Fn|8Custodes Power Armour}} The Mk.II Pattern was standard for the Legiones Astartes during most of the [[Great CrusadeAdeptus Custodes]], and its helmet are clad in particular became a symbol for the Legiones Astartes throughout the Imperiumfinely wrought golden armour. By the ending stages of the Crusade, Mk.II Their Power Armour had been phased out for the Mk.IV but many Legions still possessed them in great numbers. In particular, Legions not favored by Warmaster is made from [[Auramite]] as opposed to [[HorusCeramite]] or had many units spread out on the frontiers of the Imperium retained the largest amounts of Mk.II Armour.{{Fn|52}}

Crusade ===Vratine Power Armour===*{{main|Vratine Armour}}Vratine Armour is fully plated, and the legs are also power armoured. The plates are arranged into articulated hoops, for increased maneuverability.

However, this which shares design could not be copied over to elements with both the new powered leg power armour, which resulted in exposed cabling on the backs of the lower legs.

The helmet ===Inquisition===Power armour is fitted with automatic sensory devices developed on Marsalso favoured for use by agents of the [[Inquisition]]. These suits of armour enhance the user's strength, which allow the wearer to see for operation in hostile environments, and hear include auxiliary systems such as [[vox]]-links and auto-senses. Like the [[Adepta Sororitas]] though , those who lack of a form of direct interface such as [[Black Carapace]] cannot fully interface with these patterns power armour and some patterns are not wearing a helmetbuilt for such interface,and these users do not enjoy the same strength enhancements and other advanced support systems typical to Astartes power armour.{{Fn|12a}} andHowever, since all information is transmitted some Inquisitors such as [[Amberly Vail]] do wear bodygloves that connect to a computer dermal [[Imperial_bionics#Interface_Port| Interface Ports]] that mimic the Black Carapace, in the helmet before being transmitted directly to same manner as the wearer's brain via neural link, it enhances sight and hearing while dampening blinding lights and deafening noisessome Sisters of Battle.{{Fn|820}} The wearer is {{Fn|21}} An alternative method of interface with Power Armour also able to see in the infra-red and ultra-violet spectrumsexists via [[Imperial_bionics#Mind_Impulse_Unit| Mind Impulse units]], images can be zoomed in and magnified while noises can be enhancedeschewing direct physical connection with wireless control of power armour.{{Fn|122}}{{Fn|19c}}

Mark II armour is believed by many to still be the most efficient example of power armour design, although with the caveat that the overlapping hooped armour plates are difficult to repair. It can still be found in operational use - in extremely limited numbers - amongst several [[Space Marine Chapter]]s.{{Fn|1}} Mark II armour had several subtypes, such as the Paravane subtype used by the [[Dark Angels]], which was known for its exceptional void endurance and enhanced systems. {{Fn|55a}} <div class="mw-collapsible mw-collapsed" style="width:100%">*<b>Gallery of Images and Armor variants</b><div class="mw-collapsible-content"><gallery heights="250px" widths="400px" mode="packed" caption="Images and Variants">DAHeresyArt.jpg|[[Dark Angels]] Mark II Armour (Paravane sub-type) {{Fn|55a}}TSEarly.jpg|Pre-[[Magnus]] [[Thousand Sons]] Mark II Armour with Stygian-pattern helm{{Fn|54c}}TSHH.jpg|[[Thousand Sons]] Mark II Armour Achaean Sub-pattern variant{{Fn|35}}IWDecimator.jpg|[[Iron Warriors]] Mark II Armour with Decimator sub-pattern helm{{Fn|54a}}WSHeresy.jpg|[[White Scars]] Mark II Armour with Qayan-Pattern helm{{Fn|55b}}WEHeresyEra.jpg|Heresy-era [[World Eater]] in Mark II Malleus Power Armour with [[Sarum]]-pattern helm.

In these sources, the wearers of this class also bear a singular weapon thought to be related to the almost obsolete volkite, some manner of [[Disintegration_Weapon|disintegration beamerOrdo Malleus]].{{Fn|48}} It was made available between Mark II and Mark III{{Fn|63}}{{Clear}} ==='''Mark III "Iron Armour"'''===[[File:Mk3 iron armor 200.jpg|thumb|250px|Mark III Iron Armour{{Fn|60a}}Inquisitor]]This model dates from the wars of the [[Great Crusade]], when Astartes Legions were forced into deadly boarding actions and tunnel combat.{{Fn|Conflicting sources}} This armour was ideal when cover was minimal and combat was a matter of frontal assault.{{Fn|1}} The most visually brutal and imposing of all the widely produced armour marks, the Iron Armour was a heavy, modified Mark II design (itself the first mass-produced Power Armour of the Crusade era). The Iron Armour's structure has augmented frontal defence and incorporates additional ablative plates, and is intended foremost for use in boarding actions, tunnel assaults and void warfare, although it is considerably heavier and more power hungry than its contemporaries.{{Fn|9}} The new helmet design is a heavily armoured model with sloping plates designed to deflect shots to the left and right, and inspired the Mark IV and VI helmet designs.{{Fn|1}} Mark III was never intended to replace Rare even among the previous Mark but to act as an optional suit specialised for situations where heavier frontal protection would be advantageousHoly Ordos, such as in the close confines of spacecraft and mining complexes.{{Fn|8}} Because of this, no Legion was ever fully equipped with the Mark III. While successful in the conditions it was designed for, the power armour is too clumsy and uncomfortable for conventional fighting. Nonetheless it became widespread inscribed with pentagrammatic wards in some Legions, such as the [[Imperial Fists]] and [[Death Guard]]. Meanwhile vaults deep below the [[Dark AngelsTricorn Palace]] and [[Space Wolves]] also favored the design, perhaps due to its more bellicose nature.{{Fn|52}} The Mk.III is sometimes worn by ceremonial guards due to its visual brutality, and can also still be found used in close-quarters situations by various Space Marine Chapters. It is commonly called the Iron Suit or ''Armorum Ferrum'' in recognition of its great strength.{{Fn|1}}{{Clear}} ==='''Mark IV "Imperial Maximus Suit"'''===[[File:Mk4 maximus armor 200.jpg|thumb|250px|Mark IV Maximus Armour{{Fn|60a}}]]At the end of the [[Great Crusade]] the [[Space Marines]] found their armour wearing out. While some Legions chose to continue local production and maintenance, the [[Adeptus Mechanicus|Mechanicum of Mars]] started to design a new variant for centralised issue, which was to be designated the Mark IV or ''Imperial Maximus'' suit.{{Fn|1}} At the Mark IV stage of the power armour development, Space Marine armour began to take on an appearance recognisable as contemporary power armour, the main change being the abandonment of the separate abutting plates in favour of larger inflexible armour casings incorporating flexible joints. This marginally reduced mobility but was far easier to produce and maintain.{{Fn|1}} Technical secrets recovered on newly conquered worlds allowed Mars to develop the more efficient armour, improving the quality of protection and reducing the suit's weight at the same time. Improved armouring of the power cables allowed the main arm and chest supply to be safely relocated to the exterior of the armour, while the use of new material reduced the size and number of cables.{{Fn|1}} The helmet was a completely new design, the basic shape inspired highly prized by the sweeping front of the Mark III. In Mark IV and later versions the helmet is no longer fixed, but moves with the wearer's head. This represented the constructors' increasing experience with neural connector gear and the new materials which flooded into the Martian workshops as the Crusade progressed.{{Fn|1}} Mark IV armour was envisioned at the time those who expect to be the ultimate and final type of Space Marine armour, able to offer the best protection in a variety of conditions. Many of the Space Marine Legions were entirely or partially re-equipped with it, although the order of which Legions received the armour would shortly prove to be of significance.{{Fn|1}} As a result of its widespread production and use prior to and during the fight [[Horus Heresydaemons]], Mark IV suits are the most common of the pre-Heresy armour Marks still in service during the 41st Millennium. The Pattern was initially most widespread in Legions that were favored by Warmaster [[Horus]], and thus would become synonymous with Traitor Astartes.{{Fn|52}} Notably, a few Chapters, such as the [[Red Scorpions]] and [[Iron Hands]], are still capable of producing new Mark IV suits in the 41st millennium.{{Fn|9}} The round nozzles on either side of the backpack are not only for heat dissipation but also could be used as stabiliser jets in zero gravity conditions.{{Fn|27}}<div class="mw-collapsible mw-collapsed" style="width:100%">*<b>Gallery of Images and Armor variants</b><div class="mwhand-collapsible-content">*'''Achean Pattern'''[[File:Achean Pattern Thousand Son.jpg|thumb|right|170px|Achean Pattern]] Helmets and Shoulder Pads were a variant Mk IV ‘Maximus’ battle plate design of the [[Thousand Sons]] [[Space Marine Legion|Legion]] during the [[Great Crusade]] and [[Horus Heresy]].

Many of the Legions that had just been fully equipped with Mark IV armour turned against the Imperium while many of the loyal Legions had been deliberately starved of access to it and remained operating with the older Mark II and Mark III armour. Additionally, even the Legions equipped with Mark IV suits quickly found themselves low on spare parts and unable to manufacture replacement units. With war damage and mobile operations, resupply for damaged equipment was difficult or impossible. Marine artificers and [[Techmarine]]s had to use old style equipment from older models to keep the legions fighting, as well as salvage from slain enemies and unorthodox innovations of their own.{{Fn|1}}{{Fn|8}} This ad-hoc assemblage of various armour mark segments must have good (including new or unoffical design elementsdesperate) being created by a multitude of legions resulted in an entirely new mark of armour being 'accidentally' created; these previously non-standard, emergency/stopgap designs were retroactively termed as the Mark V once production of the Mark IV was halted and the design for the subsequent Corvus Armour mark (Mark VI) was finalised. Some form of standardisation across Mark V suits is notable, despite their apparently random creation and individual varied origins, due to the dissemination of molecular bonding techniques across the legions. These techniques were developed due to battlefield experience in fighting other [[Astartes]]; Astartes plate needed to be proof against their own penetrator weapons, and it was discovered that power armour would benefit from additional reinforcing in this regard.{{Fn|6}} All sorts of improvised additional armour can be seen on Mark V suits, but the most common technique was affix additional layers of armour with the aforementioned molecular bonding studs. This relatively quick and simple technique effectively added another ablative layer to marine armour suitsreasons. The extra weight this generated would prove considerable, however, which placed a strain on power supplies. As wards inscribed onto the addition of extra power generation sources and cabling would just require more armour plating, catching the design in an eternal circle, the wearers of the suit was forced to either deal with the additional weight, or turn up the power output of his backpack but suffer extreme heat output, which not only would prove uncomfortable and even compromising in certain situations,{{Fn|1}}{{Fn|8}} and in many cases older, heavy power cabling was used, which created a weak point on the chest{{Fn|8}} Many Mark V suits ended up featuring an unusual helmet design appropriated from supplies generated by the [[Tactical Dreadnought Armour]] program; this spin-off helmet featured similar levels of improved auto-senses as Terminator suits, but was still found to be inferior to those of Mark IV suits.{{Fn|1}} The respirator used for this helmet was codified as the Mantilla-pattern, and saw use as early as late [[M30]].{{Fn|10}} The Mark V would be the most common armour mark visible during the Horus Heresy, by its nature as a mark resulting harm Daemonic creatures who directly from strike the concerns of that galactic civil war. As a result, the Mark V is commonly called the Heresy Suit and is distinguished by the molecular bonding studs often seen on areas such as the helmet, shoulder plates and greaves. Few Imperial Space Marines are ever seen in Mark V suits today, as the loyalist Chapters either broke up these suits for spares or purposefully destroyed them after the Heresy was over. In contrast, many [[Chaos Space Marines]] still wear Mark V armour by default{{Fn|1}}, either because they still possess their original suits or because they are forced to scavenge equipmentwearer. The Mk.V became most prevalent in the [[Shattered Legions]] due to their more desperate situation.{{Fn|52}} This power armour carries resonances of the Imperium’s darkest hour and its greatest victory. Battle-Brothers will offer the wearer their respect. However, members of the Inquisition wards are instinctively suspicious of any connection to the Horus Heresy.{{Fn|8}} ;Production Mark VProduction Mark V is the most widely recognisable form of Mark V, and consists of elements of power armour that most Legions were able to manufacture in their own forges, or otherwise obtain themselves, falling back on common designs for parts that had specific cross-compatibilities, often deriving from Mark IV, V, VI and later Mark VII.{{Fn|48}} ;Non-production Mark VNon-production Mark V is a genuine amalgamation of field modifications combining several different marks of armour in ways no Tech-Priest would ever think to sanction. In general, Mark II and III components can be combined without issue, as can those of Marks IV, VI and the much later Mark VII. Parts outside these two distinct groups can only be combined with one another with great difficulty, however, and so this was often only seen in the more technically adept Legions such as the Iron Hands and Salamanders - in particular those elements of the [[Shattered Legions]] that were cut off from ready sources of resupply in the wake of the treachery temporary at Istvaan V.{{Fn|48}} ==='''Mark VI "Corvus Armour"'''===[[File:Mk 6 corvus armor 200.jpg|thumb|250px|Mark VI Corvus Armour{{Fn|60a}}]]At the end of the production of Mark IV armourbest, some failing after a long term research project began to replace it.

Mark VI armour offered no better protection-levels than the Mark IV, but incorporated more efficient internal systems where power-routing and auto-sense were concerned. Power systems were given back-up redundancies with no increase in weight, while both olfactory and auditory sensors were improved. Additionally, the armour featured the best stealth capabilities of all power armour marks so far designed,{{Fn|6}} as well as a new method of compartmentalising components hoping that allowed them to be swapped out with pieces from previous marks with ease.{{Fn|1}} It is the lightest variant of power armour and featured dual technology circuits that allowed the replacement of rare their death they might still weaken or sophisticated parts with common or basic alternatives.

The left shoulder armour features the tell-tale molecular bonding studs of Mark V armour. The initial suits did indeed use the ablative technique pioneered in Mark V suits, as paucity of supplies during the Heresy meant that some sacrifices still had allows it to be made, even with operate for a new armour designweek without recharging. In later years, the left shoulder was armoured to the same level as the rightAlternatively, but the studs were still affixed in a deliberate continuation of the honoured design that had won the Horus Heresy for the Imperials.{{Fn|1}} The [[Alpha Legion]] was able to acquire small numbers of Corvus Armour and modified it according to their Legion's own needs. Built in secret, the "Corvus-Alpha" pattern of Corvus Armour saw use openly during the [[Horus Heresy]].{{Fn|19}}  Chaos Space Marines can be seen in this armour despite its association with Imperial Space Marines; they captured a significant quantity of the suits on Mars during the Heresy, as well as Mechanicum production facilities, and were therefore able to produce their own Mark VI suits.{{Fn|1}} Mark VI armour was first issued during the later stages of the Great Crusade, and it was in wide service by the time of the Horus Heresy. And while it may be most associated with forces who employed stealth and infiltration tactics such as the Raven Guard or the Alpha Legion, every Legion was issued with this mobile, relatively lightweight armour mark – even the Iron Warriors, who were well-known for their preference for heavier armour.{{Fn|51}} By the time of the Siege of Terra, Mark VI was the most numerous pattern in service, the Loyalist Legions defending the Imperial Palace had whole Chapters equipped with Mark VI armour, while the Dark Mechanicum hacked the data vaults of those still loyal to the Emperor to provide the designs to Horus and his forces. With countless Forge Worlds under the control of the Warmaster, production of Mark VI armour continued apace, and the Emperor’s Children in particular used it en masse during the Siege of Terra. The predominance of the Corvus armour would continue well into the Scouring and the present age. {{Fn|48}}{{Fn|51}} Within the Warhammer 40,000 community, Mk.VI armour is often called "beaky" or "beakies".{{Fn|49}} <div class="mw-collapsible mw-collapsed" style="width:100%">*<b>Gallery of Images and Armor variants</b><div class="mw-collapsible-content"><gallery heights="200px" widths="300px" mode="packed" caption="Images and Variants">MkVIWolves.jpg|[[Space Wolves]] Mark VI helmet variant{{Fn|53}}CorvusAlpha.jpg|[[Alpha Legion]] Mark VI "Corvus-Alpha" variant{{Fn|54e}}</gallery></div> ==='''Mark VII "Aquila Armour"'''===[[File:Mk7blank.jpg|thumb|250px|Mark VII Aquila Armour]] Mark VII armour, also known as the “Aquila,” “Imperator”, “Eagle” armour{{Fn|1}} or “Armorum Impetor”{{Fn|39}}, was developed during the Horus Heresy, and remains in use as one of the most common form of power armour ten thousand years later. It represents the final major development of Mark VI armour.{{Fn|1}} While the final battle for Mars was underway, the Imperium realised the planet would eventually be lost. Armour development teams were transferred to Earth to continue, incorporating their latest work into the armour type that would become Mark VII.
