Powered Armor

"Feels like you can take on the whole Universe in there, doesn't it?"
 -Attributed to Llucerian Morningstar, Luminarch of The Ist Legion as he spoke to the rediscovered Xann Vakosa, Luminarch of the IXth Legion upon her first donning of Power Armor
Imperial Power armor stands as a pinnacle of advanced combat gear, serving as the formidable battle-plate primarily worn by the esteemed Imperial Legions. Nevertheless, customized variants have been developed for employment by mortal forces within the Stellar Imperium. These exoskeletal suits, often fully enclosed, boast a fusion of cutting-edge technologies, combining shaped Trungenite and plasteel plates, intricate circuitry, and delicate hydraulics. The outer layer varies, offering either ceramic Trungenite or Adamantine ablative layers based on the wearer's requirements or station within the Imperiums Militant Hierarchy.
Beneath its imposing exterior, each suit of Power armor is equipped with a comprehensive suite of life-support systems, ensuring the wearer's survival in hostile and variable environments. These systems include automated medicae capabilities, providing rudimentary first aid to an injured wearer, as well as state-of-the-art tactical targeting and threat analysis systems collectively referred to as Automatic Neuro-linked Smart senses or simply "smart-senses."
Despite its imposing weight and bulkiness, Power armor design incorporates electrically-motivated fiber bundles that mimic and enhance the wearer's movements, augmenting their physical prowess. For the Imperial Marines, this augmentation surpasses their already impressive superhuman abilities. In a symbiotic union with the wearer's nervous system, a Marine's armor seamlessly integrates, creating a haptic layer that enhances their performance on hostile battlefields. Crafting a single suit of power armor demands an extensive time investment, often spanning several solar years, and each suit is meticulously maintained by skilled Legion serfs or even by the wearers themselves. These suits are revered as unique artifacts, cherished by their respective Legions for their individual spirit and storied history.
Most Power armor marks boast an array of auxiliary systems that significantly enhance the wearer's combat effectiveness. Among these enhancements are thought-activated communications systems, augurs for gathering vital information, audio filters, targeting reticules, and a multitude of other cutting-edge features.
The life support functions integrated within the armor encompass pain suppressors, combat stimulants, and anti-venoms, further ensuring the wearer's survival in perilous situations. Reinforced greaves incorporate gyroscopic stabilizers and power units that magnetize the soles of the armor's boots, facilitating combat in zero-gravity environments and vacuum voids.
While power armor is most commonly associated with the renowned Imperial Legions, it also finds application within the Emperor's Guard Regiments and among the operatives of the Ordos Quintus of the Imperial Security Systems. However, these alternate armors may not possess the same strength-enhancing properties or comprehensive life-support functions found in the Legion Tier power armor. Similarly, they may not offer the same level of protection or mobility, representing a divergence from the pinnacle of Power armor technology.
== Design ==
The formidable suits of Imperial power armor are meticulously crafted utilizing thick ceramic-Trungenite alloy plates, which encase the wearer completely. And without the aid of electrically motivated fiber bundles, these suits would prove cumbersome, but these bundles faithfully replicate the movements of the bearer whilst augmenting their physical strength. Within the realm of power armor, distinct design Generations exist, each encompassing different patterns or "marks" of armor that exhibit significant variations in appearance and function. Many of the older marks hold special significance for particular Legions, often donned by their ceremonial honor guards or elite units.
The responsibility of maintaining power armor falls upon skilled Artificers, who are typically not the direct bearers of the armor. Instead, they are mortal human servants dedicating their lives to serving the Legion. Exceptionally talented Artificers are highly celebrated, and their crafted suits are held in great esteem. 
The fully sealed nature of power armor isolates the wearer from the external environment, safeguarding them against chemical and biological weapons, as well as toxic atmospheres. Furthermore, power armor commonly incorporates a multitude of auxiliary systems, including radio frequency communicators, smart-senses, and more.
The Neuro-Enhanced Machinery Operating System (NEMOS) Link, a sophisticated biotechnology facilitates the integration between the human nervous system and machine systems, be they weaponized or otherwise. This advanced system of neuroactive, black fibrous material is carefully implanted directly under the skin of the Bearers torso, thighs, upper-arms and forelimbs, in conjunction with The S.I neural augment that spans along the spine. This biomechanical link establishes a direct and instinctual neural connection between the Bearer and their power armor, effectively transforming it into a seamless second skin.
The advanced systems integrated into Imperial power armor continuously monitor the Bearers biological functions through the NEMOS and S.I, relaying pertinent medical data to the wearer and, if necessary, to the Imperial Medical Forces in the event of injury.
Located within the posterior power-pack of the armor is its primary power source—a Micro Arc-Reactor, a sub-atomic microfusion generator. Additionally, a backup solar power converter and a set of 100 micro solar cell batteries are present to store absorbed solar energy.
The backpack also houses the armor's environmental and life support systems, along with supplementary movement stabilizer thrusters designed for combat in low-gravity or zero-gravity environments.
== Armor Components ==
Component: 	Function:
Ceramic Trungenite-Alloy Outer Shell 	The outer shell of the Power Armor consists of a fairly 3-Layer thick titanium alloy. This plating covers the chest, arms, hip, legs, calves, feet, and hands. The alloy is extraordinarily resilient, can take significant punishment, and is nearly impervious to small arms fire.
While enough shots from armor piercing rounds (Such as Ark-Bolts, Plasmor Steams or Auger Rounds.etc) will breach the outer shell, the armor can take a few glancing blows from them without compromission. The outer shell of all Power Armor suits is covered with a refractive coating to help disperse the heat experienced from Energy based weaponry. However multiple direct hits from any Energy weapon will compromise the armor plating.
Helmet 	The armored reinforced headgear that protects the head.
The Helmet is one of the most vital aspects to the AEGIS system. It contains key features like the Heads-up display that links to the Brain and Limbs, and can identify equipment and display information about it when it is picked up by the bearer. Another feature is the direct neural interface system which connects to any neural implants donned by the Bearer. Two core processor chips are implanted into the Marine’s skull in the rear of the head. Which is comparable to an on-board computer using parts of the human brain for processing - when the connector at the rear of the Marine’s head and receptors in the brain link to the helmet's on-board sensors, it creates the neural link needed to move the AEGIS Suit.
The helmet also contains other equipment to protect and aid the user in hostile conditions. This includes: filters to remove toxins from the atmosphere, a supply to provide air to the wearer during EVA, thermal and motion sensors, communications, solar-powered lighting, and imaging and video gear. The helmet also contains the V.I housing, where the armor's False Anima, an armor-bound false intelligence, is primarily housed.
Smart-senses 	Electronic sensory devices and miniaturized cogitators that monitor the surrounding landscape and feed auditory and visual signals directly to the wearer's cerebral cortex through a neural feedback mechanism. This assortment of Smart-Senses can further enhance a marine's already superhuman sight and hearing, while at the same time dampening any blinding flashes or deafening explosions. These smart-senses, as well as the other internal improvements, have become standard equipment in every subsequent pattern of Imperial power armor, whilst lesser iterations have been integrated into Emperor's Guard Full-Steel Jackets and Carapace Armors.
Photo Lenses 	The photo lenses are the reinforced eye guards in the helmet that protect the wearer from dazzling light bursts. They also allow them to see into the infrared and ultraviolet ranges, as well as enabling vision in low-light conditions.
Respirator Comm-Link 	The RCL can amplify a wearer 's battle cries to deafening volumes. Also contained within is 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 armor that protects the throat.
Spaulder 	The auto-reactive shoulder guards are shaped to deflect as well as absorb incoming blows, these smaller shoulder plates are often bare, but rarely can be used to display Marine identification markings, including Legion/Cohort symbols, company and squad markings, as well as many other honor badges.
Pauldron 	These auto-reactive shoulder guards are modularly attached to Spaulders, and are shaped to deflect as well as absorb incoming blows better. These larger and more diverse shoulder plates typically display Marine identification markings, including Legion/Cohort symbols, company and squad markings, as well as many other honor badges.
Gauntlet 	The armored glove that protects both the hand and the wrist.
Cuisses 	The thigh protection component of the armor, specifically designed with larger dimensions and thicker plates. This deliberate construction aims to provide enhanced defense to this critical area of the wearer's body. In some variations, the Thigh Guard features strategically placed empty spaces, reminiscent of pockets, which serve versatile functions. These hollow compartments can be utilized to store additional ammunition or serve as convenient storage for emergency combat stimulants, ensuring swift access to vital resources during intense combat situations.
Plastron 	The armored chest-plate that is designed to protect the suit's armored power cables, and more importantly, the Bearers vital organs. It is typically adorned with the Tri Headed Imperial Aquila or the Imperialis honor for more veteran Soldiers.
Couter 	Part of the armor that protects the elbow.
Vambrace 	Part of the armor that protects the forearm.
Poleyn 	Part of the armor that protects the knee.
Greaves 	Part of the armor that protects the lower leg. The greaves often incorporate gyroscopic stabilizers and power units that can magnetize the soles of the armor's boots for combat in zero-gravity or other unstable conditions.
Sabaton 	The armored boot that protects the foot.
Life Signs Monitor 	Most marks of power armor contain a suite of life-support functions, including an auto-medicae equipped with various painkillers, combat stimulants and anti-venoms.
Temperature Regulator 	Power armor automatically maintains the wearer's temperature. Heat is provided by the power core and thermal build-up can be vented via the armors' distinctive vents. As a result, a Marine with their more advanced armor can fight anywhere, whilst the versatility of power armored mortals is highly increased. With a Marine being capable of fighting in the cold vacuum of space or the raging heart of a volcano, without noticing the change of temperature.
Nutrient Reservoir 	Most power armor contains a self-replenishing, high-energy liquid food store that can sustain a wearer's metabolism without need for further nourishment. During battle, there is no need for an Armored warrior to stop to eat or drink.
NEMOS Link 	A neuroactive, black organic fibrous material that is implanted directly under the skin of the a high ranking warriors torso, thighs, and upper-arms, along with The S.I that runs along the spine. Points are then cut through the Interface by Medical Personnel using surgical tools that allow the User to directly interface their central nervous system with their Power Armor's cybernetic systems along with Nerve Integrated Weaponry. After a few solar hours, the material hardens and invasive synthetic fiber bundles that will serve as connection points for neurons grow inward and interlink with the Bearer's central nervous system.
Spinal Conduit 	The Spinal Interface, also called the Ferro Animus. The S.I is implemented to aid the Interface to make movements within bulkier and more robust Power Armor Marks much more fluid and precise.
Force-Multiplying Circuits 	Integrated within the armor, there are power-enhancement systems that amplify the force exerted by the bearer. These systems notably facilitate hand-to-hand combat, providing the wearer with increased strength and agility. However, adjusting to these modifications during initial utilization can prove challenging. Even a slight motion, if executed improperly, has the potential to result in unintended and potentially harmful consequences.
Due to these inherent risks, the utilization of these strength modifications is limited to Imperial Marines and individuals equipped with the NEMOS and S.I technologies. The formidable physiology of Imperial Marines allows them to withstand the heightened power and rapid movements enabled by these enhancements. On the other hand, the NEMOS Link plays a pivotal role in synchronizing the human mind with FM-Circuits, effectively mitigating unwanted movements and excessive force. 
This synergy aids to prevent potential dangers such as broken bones or even fatal injuries caused by spasms resulting from the excruciating pain of fractured limbs. For un-augmented mortal bodies, the strain induced by such modifications would pose severe risks, making them unsuitable candidates for utilizing the strength enhancements without risking severe harm or even death.
Titano-Plasteel Nanocomposite Undersuit	Nestled between the external armor and the internal padding lies a robust black armored bodysuit, crucial for the safety and survival of the bearer. This specialized bodysuit boasts a multitude of small yet vital functions, working in unison to ensure optimal performance. Crafted from a titanium-based material, the bodysuit strikes a remarkable balance between strength and flexibility. Not only does it fortify the wearer's resilience, but it also acts as an additional layer of defense against ballistic assaults, reinforcing the armor's protective capabilities.
Furthermore, the bodysuit features a heat-resistant coating that efficiently disperses and dissipates heat generated by energy-based weaponry. This vital attribute prevents the wearer from succumbing to the potentially devastating effects of excessive heat, safeguarding their well-being amidst the chaos of battle.
Mag-lock Holster 	The Mag-Lock strips are small, yet powerful magnets placed on the legs, hips, waist, and back of the suit, and are used to hold any equipment with a magnetic property. The suit also contains an electromagnetic system on the boots of the armor that allow its bearer to stay attached to a metal surface even in Zero G environments, and can be toggled on or off by the bearer.
Hydrostatic Gel 	Underneath the armored bodysuit is a gel-filled layer. The gel layer regulates the temperature of the suit and can reactively change its density to conform to the bearer’s shape. The hydrostatic gel layer can also be pressurized to various levels to potentially save the bearer’s life. Severe or sustained trauma to the armor can cause the gel layer to become viscous, rendering it partially or completely ineffective
Enviro Pressure Seal 	The Pressure Seal is a vital component to the Armors protective systems. It keeps the armor airtight, in either underwater or void based combat zones. The seal is very strong and will only break under extreme pressure, such as in a high velocity impact or when the Hydrostatic Gel has been over pressurized.
Arc-Reactor 	The Primary power source of The AEGIS. The Arc-Reactor is the most essential part of the Armored Power System, as it provides power to all equipment on the Luminaire Armor. The reactor is built into the Armor and allows for nearly unlimited movement. The Arc-Reactor in all versions of the Luminaire Armor are half the size of a normal fusion pack that conventional infantry carry around.
Ark Shield Generators 	The Shield device was reverse engineered from Alfen technology. Jovian Tech-Priests would spend the next 100 years attempting to make some use of the technology. For decades, the attempts at cracking their technology had met with repeat failure. Some had given up, and others in the scientific community believed the energy shield technology could never be cracked; however, at some point before M94, a breakthrough was made, and for the first time, the Empire had successfully cracked and improved upon the stolen technology.
== History and Development ==
"Shells, blades, fire or claw - none shall slow the march of a power armored Son of The Emperors Legions."
Power armor has been in use by humanity millennia before the Age of the Stellar Imperium, utilized by humanities armies in the Golden Age of Mankind, and inevitably worn by the techno-barbarian clans that dominated Terra during the Long Dark. It would also be 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 Long Dark in the 90th Millennium.
In the armor's earliest incarnation, the suit was not fully sealed or life-supporting, being an unnecessary function whilst its use was still confined solely to Terra. But over the history of the Imperium though, power armor has developed into many different forms. Need, circumstances and the recovery of new materials and lost advanced technology, this so-called archeotech, has shaped the armor's evolution. The common image of the Emperor's Imperial Luminous Marines is of mighty warriors arrayed in imposing suits of armor made of ceramic Trungenite plates, adorned with the Heraldry of their Legions and Homeworlds. 
All the recent types are still in active use, to varying degrees, by the existing Imperial Legions, whilst earlier pre-powered patterns have been seconded to other arms of the Imperial Army. And working examples of the older powered marks, meanwhile, are often extremely rare and valued as a physical link to the history of the Imperial Marines. Older patterns of power armor are reserved for ceremonial guards or used as the badge of office of high-ranking officers. It may be noted that there appears to be a steady improvement in engineering and design through the years.
However this progress is often not because of any particular invention or creativity. Rather, the changes were triggered by the gradual rediscovery of knowledge and materials from the Golden Age of Technology, as the Emperor's Great Crusade reconquered the galaxy.
== Armor Iterations ==
The AEGIS (Advanced Exoskeletal Gear for Integrated Supremacy) Powered Assault Armor, also known as The Luminous Armor in its later iterations, represents a pinnacle of technological advancement in the realm of combat exoskeleton systems. Specifically engineered to enhance the physical capabilities of the esteemed forces within the Imperialis Militant, the cutting-edge armor of the Stellar Imperium provides a monumental boost to strength, speed, agility, reflexes, and overall durability. It serves as a game-changing asset across the entire spectrum of the Imperium's military, extending from the formidable Mortal armies of the Emperor's Guard Regiments to the battle-hardened Imperial Legions and their Luminarch Leaders in the heat of conflict.
== Gen 1 Imperial Power Armor Variants ==
Armor Mark: 	Overview:	Image:
Mark I Daedalus Super-Soldier Weapons System: Basalic Pattern Power Armor	Known by Imperial Historians as the Daedalus Super-Soldier Weapon System, The first pattern of power armor created for the I'cartes and few of the first true Imperial Marines was the Mark.I Basalic Pattern Power Armor, though the name was later assigned by the Jove-Denarion Tech-Guilds after the fact and at the time of its use the suit was simply called "power armor." The initial design plans were not completed until Dr. Nysa and Sr. Research Engineer Dr. Lethos acquired the funding and assistance for their Weapons Research Project; The AEGIS (Advanced Exoskeletal Gear for Integrated Supremacy) Platform, and brought the armor system into existence. Its design was developed from recovered sets of rudimentary powered combat armors worn by the techno-barbarians that had plagued Old Terra throughout the Long Dark. And instances of it's Design would be fielded through the Mid-to-Late Terran Unification Wars, and throughout the Sol Reclamation.
However, because it was designed with fighting in a terrestrial environment solely in mind, it was not fully enclosed, with no means to support the wearer in a vacuum. Only the lower body was powered, due in part to the fact that during the Emperor's conquest of Terra, high-powered ranged weaponry was difficult to make due to technological constraints, and so a warrior's lower-body mobility was his most important asset. The main part of the armor was the massive powered torso made up of overlapping plating which enclosed the torso. Coiled energy cables beneath the armor plating transmitted energy from the power pack on the back to the legs, greatly increasing the warrior's lower-body physical strength as well as speed and mobility.
The Mk.I Basalic Armor would gain its name from the fact it is the primogeniture base of all subsequent Patterns, Marks, Sub-Patterns and Scionic-Designs of Imperial Power Armor. That fact gave the armor its most common present-day name — Basalic Armor.	
== Gen 2 Imperial Power Armor Variants ==
Armor Mark: 	Overview:	Image:
Mark II: Carapace Armor 	During the waning years of the Terran Unification Wars, as the Firstborn of the Imperial Legions were taking shape and heralding in the dawn of the Stellar Imperium, the development of the Mark II Carapace Armor came to fruition. Designed by the greatest of Erikan and Taipanite minds, this formidable design of armor would play a pivotal role in the final battles of the Unification Wars and throughout the campaigns of The Sol Reclamation Wars, aimed at reuniting the Worlds of the Sol System under the banner of the nascent Imperium.
Emerging as a frontline assault armor platform to be utilized by the First, Second and Third-Founding Imperial Legions. Its advanced design incorporated the latest technological advancements and battlefield innovations at the time. Providing not only unparalleled protection but also significantly enhancing the bearer’s combat capabilities. The outer layer, composed of a multi-layered composite of reinforced plasteel and trungenite, offered superior resistance to ballistic and energy-based attacks. The inner framework utilized shrunken down iterations of the combat Rigs worn by the I'cartes to augment the strength and endurance of the Marine's that bore it, incorporating powered servos and muscle-mimicking actuators that allowed soldiers to perform feats of strength and agility far beyond human norms.
In addition to its protective capabilities, the Mark II Carapace Armor featured a comprehensive life support system similar to that of the earlier Mark I Combat Rig. This system included advanced filtration units to purify the air, manage respiratory functions, and provide a continuous supply of oxygen. Integrated nutrient delivery systems ensured that the Marine remained nourished during extended operations, while biofeedback mechanisms monitored vital signs and could administer emergency medical treatments if necessary.
Furthermore, the Mark II armor was equipped with, at the time, state-of-the-art sensory and communication systems. The helmet, with its distinctive visor, housed enhanced optics and auditory sensors that provided superior situational awareness. These systems allowed the wearer to detect threats and coordinate with allied units effectively, even in the chaos of battle. The Mk.II often was said to resemble more of a robust body armor rather than a fully-fledged powered combat rig as seen with other forces, earning it the fitting moniker of 'Carapace Armor.' 
The Mk.II and it's Sub-Patterns would serve the Legions for the decades of the Reclamation and even the opening years of the Imperial Great Crusade, but as with all things, as advancements in power armor design for the Legions took center stage with the coming of Greater minds and designs, the majority of Mk.II suits, along with their subsequent sub-patterns, upon being replaced by the Mk.III and beyond, found their purpose in serving the Emperor's Guard regiments in the form of repuposed Automata and shrunken down armor for elite mortal forces.	
-Mark II Sub-Pattern: EVA Armor- 	The Mk II Carapace Armor Sub-Pattern: EVA (Extravehicular Activity) had been specifically tailored for Legiones Combat Operations conducted in the void of space. As such, the Sub-Pattern features the notable inclusion of an advanced Low-Grade Adamantine-composite visor. Of which would expand over the helmet's anterior plating upon the exposure of a vacuum enviroment, serving to mitigate the detrimental effects of infrared radiation emitted by stars and other cosmic radiation hazards.
The EVA variant of the Mk.II is predominantly donned by Legion Void-Engineers who undertake crucial repair operations in the unforgiving expanse of open space, along with assault troops that upon the Hulls of Battleships during Naval Skirmishes. Suits designed specifically for Void Operations will boast a noticeably more reinforced set of plating, with its design focusing on providing micro-meteor resistance and shielding against hazardous radiation.
To enhance the movement capabilities of the armor, it is often equipped with Omni-Directional Void Gear (ODV). The equipment, developed by Chixian and Taipanite minds under the Stellar Imperium, enabled remarkable mobility in void operations. By incorporating many magnetoplasmadynamic thrusters into the OVM harness, bearers would gain the ability to navigate in a three-dimensional space rather than being confined to a two-dimensional plane.	
-Mark II Sub-Pattern: Advanced Hazard Operations Armor-	The Advanced Hazard Operations Armor, commonly referred to as the Mk.II-HOA or more simply as the Hazard Platform. Designed and Constructed with meticulous attention to detail, the armor incorporates a unique arrangement of microscopic laced Trungenite armored lattices. These lightweight plates are skillfully layered over and under each other, resulting in a formidable defense that exhibits exceptional durability. However, the intricate nature of this armor configuration renders repairs a time-consuming task. Nevertheless, the trade-off for its arduous maintenance is a level of resilience that enables the Mk.II-HOA to withstand the harshest conditions.
The Mk.II-HOA would serve as a specialized suit offering enhanced protection in environments akin to the incredibly hazardous conditions prevalent on those similar to the Ju'rralae homeworlds. It found its primary utility in scenarios such as mining operations, subterranean complexes, and the confined corridors of spacecraft. In comparison to the standard Mark II Armor, the Hazard Suit boasts augmented anterior and posterior defenses, whilst the weight of the rear armor is niminally reduced in places to maintain a balanced configuration.
This specialized suit features a heavy armored anterior facial plating deliberately designed to deflect incoming shots from both the left and right sides. Notably, the design of the helmet serves as a direct inspiration for subsequent iterations such as the Mark IV helmet designs. The Mk.II-HOA would find its primary adoption among the Vth, Xth, XIth, XIVth, and XVIIIth Imperial Legions, owing to its superior protective capabilities and suitability for much of their operational requirements.	
== Gen 3 Imperial Power Armor Variants ==
Armor Mark: 	Overview: 	Image:
Mark III: Combat Augmented Reaction Rig(CARR) 	The Combat Augmented Reaction Armor, commonly known as Steel-Skin, was a remarkable creation partially conceived by the renowned Luminarch Llucerian Morningstar, utilizing innovative Lecarrite-powered Exo-skeletal designs to replace the comparatively archaic Daedal-Pattern Combat Rig utilized by the Mk.II as more and more faults began to be found in it's design. At its core, the armor derived its power from streamlined 1st Gen-Micro Arc-Reactors within the frame along with the first utilization of the NEMOS Link and S.I Cyberhybridized System wherein the Mk.III-CARR is interlinked with the Bearer's central nervous system. 
The CARR system bestowed upon the regular infantry units of the Imperial Legions an unprecedented level of defensive capability while maintaining their superior mobility, effectively enhancing their already formidable super-soldier attributes. Through the system's powered support function, wherein the upper-body was powered and supported through micro-actuators, bearers would gain access to a range of deadly and efficient weapons previously inaccessible to even the infantry units of the Legions. Continuously monitoring the user's myopotential and synaptic responses, the CARR system's advanced onboard VI mind exhibited remarkable precision in calculating the precise point of impact for munitions, while also mitigating muzzle rise through recoil compensators and separate actuators, thereby enhancing the bearer's accuracy when aiming. These actuators, integrated into the armor, significantly amplified the already extraordinary physical strength and speed of the superhuman wearer.
Furthermore, the suit incorporated it's own onboard micro magnetoplasmadynamic thrusters, allowing the user to execute emergency evasive maneuvers to evade enemy attacks without requiring a dedicated ODV Module. While the maneuver's effectiveness was limited, it served as a valuable recourse during dire situations where the armor's defenses were on the brink of being breached, offering a chance to evade imminent danger.	
Proto-Mark IV 	Prototypes of the Mark IV Armor Platform would be extensively tested by the formidable Elite Units of the Ist Legion's Kill-Teams. Showcasing groundbreaking advancements in both design and functionality. These Prototypes were equipped with large thrusters positioned on the legs and clavicles, as well as experimental Micro-Personal Kinetic-Shielding Systems.
Combining Trungenite-Composite alloys, a semi Powered Exo-Skeletal Harness, a cutting-edge muscle-fiber and composite nano-armor control system, and an onboard Gen-1 VI machine mind, the suit provided unparalleled strength and protection. The enhanced power backpack, resembling the Mk.III's in design, now housed advanced life support equipment including air-scrubbing and fluid recycling systems. It also featured the state-of-the-art 3rd Gen Arc-Reactor power supply for the armor's operations.
The helmet would incorporate experimental electronic sensory devices and multiple simplified Cogitatation Units that meticulously and constantely monitored the surrounding battlescapes and enviroments. Through a neural feedback mechanism, visual and auditory signals were directly transmitted to the Marine's cerebral cortex, significantly augmenting their already superhuman sight and hearing. These enhancements, known as 'A.N.S-senses' (Automatic Neuro-linked Smart Senses), provided an exceptional level of perception. 
However, as with all Prototypes, it is worth noting that many of these additions were limited and outright faulty at times, with much of the sensory upgrades often resulting in intense overcompensation, occasionally overwhelming the bearer with intense deafening sounds or blinding bursts of light, albeit temporarily.

Mark IV: Thunderer 	The Mark IV "Thunderer" Armor would stand as the pinnacle of Imperial personal protection systems utilized by the Legiones. Designed to incorporate the Mk.III's CARR system whilst utilizing advancements found in the utilization of the Proto-Mk.IV. Made up of Ferro-Ceramic Trungenite alloy plates sitting atop a fully Powered Exo-Skeletal Harness formed from a mesh of sophisticated muscle-fiber and composite nano-armorial laticed control system, along with an upgraded Gen 4 VI Data-Mind.
The powered backpack, whilst retaining a similar basal shape to its predecessors, underwent significant improvements and downsizing. Now housing new state-of-the-art life support equipment, including enhanced air-scrubbing and fluid recycling systems, as well as the introduction of emergency medical first aid capabilities. The backpack also served as the power supply for the armor, benefiting from the utilization of advanced 11th Gen Micro Arc-Reactors. Micro-thrusters, powerful and finely tuned, were strategically positioned on the legs and clavicles to enhance the wearer's mobility and agility.
The Mk.IV helmet underwent significant upgrades, featuring advanced and upgraded electronic sensory devices and cutting-edge Micro-Cogitators. These sophisticated components continuously monitored the surrounding battlescape, relaying visual and auditory signals directly to the Marine's cerebral cortex through a neural feedback mechanism. The result of these advancements was the further enhancement of the Marine's already superhuman sight and hearing. Additionally, superior technology enabled the helmet to mitigate blinding flashes and deafening explosions, ensuring that the wearer's sensory experience remained optimal. These enhancements, collectively known as A.N-senses (Automatic Neuro-linked Senses), alongside other internal improvements, became standard features in subsequent patterns of true Imperial Power Armor.	
-Mark IV Sub-Pattern: Hunter-Killer- 	The specialized Mark IV Sub-Pattern 'Hunter-Killer' pattern of the Mk.IV armor was developed through a collaborative effort between the Luminarchs Anpu Symt Khener and Anikanov Zakharik, specifically for the VIIth and IXth Legions. This variant was meticulously designed to counter the extensive use of esoteric Omehgos-Pattern weaponry employed by the Umbral Wardens and Rad-Weapons of the Storm Raptors, two renowned forces known for their unconventional warfare tactics.
The key focus of the Mk.IV-HK pattern was to provide enhanced protection and survivability against the unique bio-hazards posed by these specialized weapons whilst retaining stealth capabilities. The armor incorporated advanced lining of micro-insulation materials beneath the Plating of the Mk.IV, offering superior resistance to both heat and radiation. This feature enabled the wearer to endure ever higher levels of these dangerous elements compared to warriors clad in other variations of power armor whilst retaining the mobility and silence of which the VIIth and IXth are known.
To ensure that the additional protective measures did not hinder mobility, an advanced latticed-servo system inspired by warmachines designed by Forge-Smiths of the Askari Blacks. This servo system efficiently distributed the weight of the enhanced insulation and additional defensive layers, allowing the wearer to maintain agility and maneuverability in the heat of battle. This aspect was particularly crucial for the VIth and XIIIth Legions, as their combat doctrines placed a strong emphasis on swift and dynamic engagements.	
-Mark IV Sub-Pattern: EVA Operations Armor- 	An Upgraded iteration of the Mk.II-EVA Armor utilising the Mk.IV as a base. Utilizes the same ODV Module System seen in the Mk.II.	
-Mark IV Sub-Pattern: Marauder- 	Unsurprisingly for a legion so focused on boarding, Zone Mortalis, and Siege Combat, The Astral Marauders Legion would utilized the Mk.IV-EVA armor to the near exclusion of all others, and thus were constantly at the mercy of the armor’s failings, of which there were many. Most namely being it's propensity to burning out its own lattice servo system under the combined stress of its own weight and power after continued use, meaning the armor would require near constant and time consuming maintenance.
Unwilling to accept this, Borakhutai Shogun began to experiment with the design and creation of his own sub-pattern. But eventually the Luminarch would reluctantly travel to Jupiter to gain the assistance of the Jovian Tech Guild; The Zaulk Triumvirate. Eventually culminating in the creation of the Mk.IV-Marauder Scion-Pattern. Designed as a super heavy form of power armor, one step removed from Dreadnought Armor, the suit would boast rear and anterior armor that the standard Mk.IV lacked, as well as an enhanced servo motor system designed to stop the systems burning out, though these extra muscle bundles had no effect on the armors speed, the suit still as ponderous as its standard counterpart.
The armor was also void sealed and hardened by design, rather than as a field modification as with other examples of such void hardening, and it was this that gave the armor its name. Possessing a self-sealing/replicating nanocomposite gel-layer to ensure cracks were plugged with an almost immediate air-tight seal, as well as an interior Micro-Hephaeston Engine within the rear, constantely running to refill the fuel reserves of both the Armor and it's Jump-Assault Systems. The 'Marauder' armor ensured its bearer could operate in airless and void environments for extended periods of time, even after the operation capability of the armor is ran more than thin.
Only the Astral Marauders ever truly made use of this pattern of armor, though aspects of its design were shared with the IInd and XIIth XXth Legions, and by M92.943, the armor after a number of revisions to accommodate the Luminous Legions was made standard across the entire legion, each warrior laying claim to a suit of the super-heavy plate.	
-Mark IV Sub-Pattern: EVA Operations Armor: Scion-Pattern: Void Hunter-	Unsurprisingly for a legion so focused on boarding and other far more dangerous Zone Mortalis combat even when compared to Legions sharing their combat philosophy, the XIIth Legion used the Mk IV Sub-Pattern EVA armor to the exclusion of all others, and thus were constantly at the mercy of the armor’s failings, of which there had been many. Heavy, slow, and prone to burning out its own servo motors under its own weight after continued use meant the armor required constant and time consuming maintenance.
Unwilling to accept this, Flumenel Wetekina Kua began to experiment with his own armor, eventually he would travel to the Tech-Guilds of Viharii'byan to gain the assistance of the Tempest Mechana, all culminating the the EVA Scion-Pattern being created in the late M92.416. Designed as a light form of power armor, one step removed from Reaver armor, the suit lacked rear and front armor that the standard Mk IV had, but boasted an enhanced servo motor design, these extra muscle bundles owing to an incredible effect on the armors speed.
The armor though sporting less armor was fully void sealed and its few areas of armor plating had been extra-reinforced by design, rather than as a field modification as the Legion often did with such forms of void hardening, The armor is also often equipped with pre-powered armor Omni-Directional Void Gear(OVM), allowing its bearer to move in the 3D spaces of the Void as opposed to a 2D one through the use of magnetoplasmadynamic thrusters equipped into the OVM harness. And it were these design evolutions that gave the armor its name. 
As with its 'sibling' pattern of the Marauder a self-sealing gel-layer to ensure cracks were plugged with an air-tight seal, as well as extended oxygen tanks akin to the fuel reserves on a jump pack were implemented in its design, the 'Void Hunter' armor ensured its bearer could operate in airless environments for extended periods of time, beyond what other warriors of the legions were expected to manage.
Unlike the Astral Marauders the Drowned Drakes were not the only Legion to ever truly make use of the pattern of armor, its design was shared and integrated into the forces of the IIIrd Legions Void Claws Cohort, The VIth Legions Storm Raiders Regiment, the VIIIth Legions Lancers, the IXth Legions Death Stalkers, the XIth Legions Lunar Dancers, the XIIIth Legions Hidden Serpent Regiment, the XVth Legions Void Butchers, and the XIXth Legions Storm Fangs.
And by M92.643, the armor after a number of revisions to accommodate the Luminous Legions was made standard across most of the XIIth Legion, each warrior of the 1st to 3rd Cohorts having stacked claim to a suit of the lighter War-Plate.	
-Mark IV Sub-Pattern: Advanced Hazard Operations Armor- Steel Blooded- 	The Advanced Hazard Operations Powered Armor, also known as the Steel Blooded Armor is an alternative Mk IV armor, a hybrid design evolution with its basis in the design of the older Mk II Hazard and Deep-Dweller armors.
The Mk IV Sub-Pattern was best suited for spacecraft boarding actions and combat in confined subterranean tunnel complexes with little cover. This armor had been ideally used by Imperial Marines when cover was minimal and combat was a matter of a simple frontal assault. Because of this pattern of Power Armor's great strength, it became known as the "Steel Blooded" or Sanquis Ferrum in Imperial High Gothic.
The suit uses a heavy armored helmet with sloping plates designed to deflect shots to the left and right, thus inspiring its name as the Hazard Pattern. The helmet inspired the later Mark IV and VI helmet designs. The semi-wedge-shaped helmet (designed to deflect incoming fire from the front) formed the basis for the later distinctive Corsair helmet of the Mark VIII Pattern.
Similar to its MK II ancestors it would be primarily adopted by the Vth, VIIth, Xth, XIVth, and XVIIIth Imperial Legions, mainly due to its greater protective ability.	
== Adaptability ==
A known characteristic shared by Legion Power Armor Systems from both the Mk.II and Mk.IV is their exceptional ruggedness and remarkable adaptability. It is not uncommon to witness a suit of power armor, worn by the warriors of various Imperial Marine Legions to amalgamate various components sourced from three or even four distinct sub and scionic-patterns salvaged from fallen battle-brothers on the battlefield. The Mk.IV in particular, was intentionally designed with a modular framework in mind to enable the seamless integration of diverse components.
Within the vast array of Imperial Marine Legions, each employs a unique combination of power armor patterns, tailored to their specific needs and preferences. Some legions prioritize equipping their marines with the latest and most advanced armor patterns available to them. On the contrary, other legions hold deep reverence for the older Marks, cherishing their historical significance and endeavoring to preserve them in a state of combat readiness for as long as possible.
== No Helmet Custom ==
The practice of Imperial Marines choosing to remove their helmets in combat, especially among certain Legions like the Frostwind Hounds and Scarlet Lions, is indeed an uncommon and controversial custom within the Imperium. While it is generally frowned upon for Marines to be without their helmets, some Legions view this act as a display of honor, courage, and defiance against their enemies.
However, it's important to note that removing the helmet carries inherent risks and sacrifices. By doing so, Marines lose the benefits of their suit's A.N.S-senses, which provide enhanced sight and hearing. To compensate for this loss, Marines who choose to go helmetless often utilize earpieces or ocular enhancement devices to maintain situational awareness.
It's crucial to adhere to proper rituals and ensure a correct environmental seal when removing the helmet, which can take additional time. This practice is not suitable for combat in a vacuum or hostile atmosphere since it eliminates the suit's environmental and life support systems.
When commanding their fellow Marines, leaders who embrace this custom can earn respect and foster unit cohesion due to their unwavering willingness to face the increased risk. However, in the event of a major firefight or entry into a hostile environment, promptly donning the helmet becomes the prudent course of action.
After the helmet is replaced, it takes time for the suit's A.N.S-senses and full vox-link to reactivate, as the armor's VI Mind requires a period to reawaken. Among the Frostwind Hounds, The Carcharodon Sons and Scarlet Lions Legions, who possess heightened olfactory senses, fighting without a helmet allows them to gather information through subtle changes in scent. This reliance on scent-based perception is so ingrained in these Legions that they may experience a sense of disorientation and claustrophobia when forced to don their helmets due to circumstances.
== Other Imperial Power Armors ==
Although power armor is most closely associated with the Imperial Marine Legions, it is also used by the Imperial War Sisters and some more martial-minded Inquisitors of all four of the Holy Ordos.
Armor Types: 	Overview:	Image:
Empyrean Ward	The Elite Drake Knights Imperial Marines who serve the IVth Legions Cult Malleus as its Chamber Militant wear the Empyrean Ward Armor, a type of power armor that is incredibly well-crafted.
It is anointed and inscribed with prayers and wards, ritually consecrated and psychically-charged. Working in tandem with the Drake Knights' formidable psychic powers, the Emperean warding within the armor protects the wearer from psychic attack unleashed by the effects of the Immaterium and the Daemons it spawns, using the wearer's own psychic power as its energy source.
The armor's ritual blessings and psychic resonance also serve to confound the psychic perception of any enemy that draws upon the power of the Warp, resulting in an effect called "the Shrouding." 
As well as its psychic properties, the armor itself incorporates an Arc-Rifle weapon that is similar in function to a standard Marine Arc-Rifle, albeit with a larger design and more robust manufacture. These weapons are common to the Grey Knights and often mounted on the wrist so that they might have a free hand to wield their Nemesis Force Weapons two-handed.
The suits are generally based on components from any ImperiaI power armor designs, with a modified helmet design that is reminiscent of the Mark III.	
Seraph Armor 	The Seraph Armour, worn by the Seraphim of the Legio Seraph, is a highly specialized and prestigious power armor designed exclusively for the bodyguard of the God Emperor of Man during the Terran Unification Wars. It surpasses the standard Imperial Marine power armor in sophistication and craftsmanship, representing the pinnacle of the armorer's art.
Unlike the typical power armor made of Plasteel or Carbon Ceramic, the Seraph Armour is fashioned with the rare and precious Sola-Titanite alloy, reminiscent of the armor worn by the Emperor Himself. This golden alloy adds to the regal and majestic appearance of the Seraphim Guard. Each suit is individually crafted and customized to its wearer, making every suit a unique and master-crafted work of art.
In addition to its exquisite aesthetics, the Seraph Armour boasts formidable defensive capabilities. It is equipped with proximity sensors that provide enhanced situational awareness to the wearer, allowing them to detect and react to nearby threats more effectively. The inclusion of Refraction Field generators further enhances its defensive capabilities, making it even more resilient against enemy attacks.
The Seraph Armour embodies the honor and sacred duty of the Seraphim Guard, serving as a symbol of their dedication to protecting the God Emperor. It combines exceptional craftsmanship, rare materials, and advanced technologies to create a suit of armor befitting the guardians of the most revered figure in the Imperium.
