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}}

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.

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" widthsMalleus Power Armour=="400px" mode="packed" caption="Images and Variants">DAHeresyArt[[File:Maellusinquisitor.jpgJPG|[[Dark Angels]] Mark II Armour (Paravane sub-type) {{Fnthumb|55a}}TSEarly.jpg200px|Pre-[[MagnusOrdo Malleus]] [[Thousand SonsInquisitor]] Mark II Armour with Stygian-pattern helm{{Fn|54c}}TSHH.jpg|[[Thousand Sons]] Mark II Armour Achaean Sub-pattern variant{{Fn|35}}IWDecimator.jpg|Rare even among the Holy Ordos, this power armour is inscribed with pentagrammatic wards in the vaults deep below the [[Iron WarriorsTricorn Palace]] Mark II Armour with Decimator sub-pattern helm{{Fn|54a}}WSHeresy.jpg|It is highly prized by those who expect to fight [[White Scarsdaemons]] Mark II Armour with Qayanin hand-Pattern helm{{Fn|55b}}WEHeresyEra.jpg|Heresyto-era hand combat, and an Inquisitor who allows an [[World EaterAcolyte]] in Mark II Armour with [[Sarum]]-pattern helmaccess to it must have good (or desperate) reasons.

Many of the Space Marine Legions were entirely or partially re-equipped deal 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 [[Horus Heresy]], 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 [[HorusRuinous Powers]], and thus would become synonymous with Traitor Astartes.{{Fn|52}} Notably, a few Chapters, such as the [[Red Scorpions]] and [[Iron Hands]]other heretical forces, are still capable of producing new Mark IV Ignatus 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="mw-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]].

==='''Mark V "Heresy =Skin-Tight Power Armour"'''====Inquisitor [[File:Mk5 heresy armor 200.jpg|thumb|250px|Mark V Heresy Armour{{Fn|60a}}Obiwan Sherlock Clousseau]]The equipping of the legions was only partially complete when the [[Horus Heresy]] broke out. 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 known 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 (including new or unoffical design elements) being created by a multitude of legions resulted in wear an entirely new mark unnamed pattern of armour being 'accidentally' created; these previously non'Skin-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 Tight Power 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''' worn beneath a long cloak.{{Fn|6}} All sorts of improvised additional armour can be seen on Mark V suits, but the Like 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 suits. The extra weight this generated would prove considerable, howeverInquisitors, which placed he eschewed wearing a strain on power supplies. As the addition of extra power generation sources and cabling would just require more armour plating, catching the design helmet in an eternal circle, the wearers of the suit was forced to either deal with the additional weight, or turn up the power output favour 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 directly from the concerns of that galactic civil warhat. As a result, the Mark V Clousseau 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 said to scavenge equipment. 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 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 be 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 at Istvaan V.{{Fn|48}} ==='''Mark VI "Corvus Armourtypical inquisitor"'''===[[File:Mk 6 corvus armor 200.jpg|thumb|250px|Mark VI Corvus Armour{{Fn|60a}}]]At the end of the production of Mark IV armour, a long term research project began to replace it. As this remained a theoretical endeavour for some time, it lead to the production of the Corvus Suit as a stopgap measure, using a mixture of new and old features.{{Cite this}} The Mark VI prototype design (which bore the provisional designation of Mk V at the time) was field-tested during the [[Scalland Campaign]] by Legionaries of the [[Raven Guard]], whose experiences and comments resulted in improved design features in the finalised is unknown whether his particular armour mark. Mark VI armour offered no better protection-levels than the Mark IV, but incorporated more efficient internal systems where power-routing and auto-senses 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 is a new method of compartmentalising components 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 or sophisticated parts with common unique pattern of his 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 to be made, even with a new armour design. In later years, the left shoulder was armoured to the same level as the right, but the studs were still affixed in a deliberate continuation of the honoured design that had won the Horus Heresy for the Imperials.{{Fn|119b}} The This is likely accomplished either via [[Alpha LegionImperial_bionics#Interface_Port| Interface Ports]] was able to acquire small numbers of Corvus Armour and modified it according to their Legion's own needs.
