· The Mark 1, also known as Thunder Armour, stands approximately 7 feet tall and weighs between 500-1000 kg, serving as the Space Marine's 'second skin' powered by a nuclear reactor.
· As the first Power Armour form, it was used by Thunder Warriors and the Emperor's proto-Space Marines during the Unification Wars. Lacking environmental sealing and life support, it wasn't a true Power Armour by modern standards.
· The Adeptus Mechanicus created it to manage thousands of designs, and it was produced by local Forge Cults, lacking a unified appearance. It focused on upper body enhancement but had primitive leg protection, characterized by noise and bulkiness due to its metal plating.
· After the Battle of Mount Ararat, it vanished with the Thunder Warriors but became the foundation for all subsequent Power Armour.

· Developed during the Great Crusade, the Mark 2 was designed for warriors enduring deep space environments.
· Unlike the Mark 1, it was the first to feature environmental sealing, enabling combat in vacuum and radioactive zones. It included full life support and powered locomotion, and its helmet, equipped with standardized auto-senses developed on Mars, connected to the wearer's brain via a neural network.
· Each Legion developed its own helmet variants, and when combined with the Black Carapace implant, it felt like an extension of the body. However, issues like leg cooling problems, exposed power cables, and maintenance difficulties were noted drawbacks.

· Based on the Mark 2, it was reinforced during the Great Crusade for combat in harsh terrains like high-gravity environments, ship interiors, and caves.
· Non-essential parts of the Mark 2 were removed, and massive, fixed frontal armour and thicker ceramite layers were added, transforming it into a 'walking barricade.' The rear armour was lightened to compensate for the increased weight.
· It was characterized by high power consumption and noisy servo-motors but presented a terrifying presence during frontal assaults. The wedge-shaped helmet design, intended to deflect impacts rather than absorb them, influenced later designs.

· Towards the end of the Great Crusade, it was developed as a solution to the obsolescence issues of the Mark 2 and 3, utilizing technology acquired from conquered worlds.
· The complex structures of previous models were replaced with larger, more robust armour casings and flexible joints, enhancing lightness and ease of maintenance. Power cables were relocated to the chest area to prevent external exposure, improving protection.
· The most significant change was the helmet, which, unlike previous models, could rotate freely with head movements, greatly improving situational awareness. However, during the Horus Heresy, Horus diverted most of the production to the traitors, forcing loyalists to use older equipment.

· During the Horus Heresy, supply lines were cut, forcing Tech-priests to hastily assemble temporary armour using recycled parts from existing Mark armours. There was no standardized model; it was characterized by 'molecular bonding studs' bolting different parts together and additional ceramite/plastoid layers.
· External cabling and increased weight burdened the power supply, often requiring reduced power output to prevent overheating. Performance compromises were unavoidable.
· The helmet was derived from the Tactical Dreadnought Terminator development program but was less effective than the Mark 4. After the Heresy, Loyalists viewed it as a symbol of despair and discarded it, but Chaos Space Marines continued to use it.

· A result of a secret project focused on stealth and advanced sensor integration, designed to replace the aging Mark 5. It was intended for reconnaissance and precision combat.
· The 'beak' helmet featured a complex vox-caster and auto-sensor array optimized for reconnaissance and precision combat, with its elongated shape providing cooling efficiency and protection.
· In response to supply issues during the Heresy, power cables were rerouted behind the chest plate, and design elements facilitating field repairs were integrated. Using high-quality dual-density ceramite, it offered protection comparable to the Mark 4 while being lighter and having an improved power-to-weight ratio, enabling quiet and stealthy movement.
· Named in honour of Primarch Corvus Corax, the Raven Guard and Alpha Legion proved the effectiveness of this armour.

· Developed in the Imperial Palace's under-halls during the Horus Heresy and completed just before the Siege of Terra. Its most significant feature was the reinforced chest plate, concealing internal power conduits behind thicker, more intricate armour, greatly enhancing frontal survivability.
· The Emperor's double-headed eagle insignia became a symbol of loyalty, originating from the Emperor's Sons Legions and bestowed upon all Loyalist Space Marines.
· The helmet was designed to be simpler and easier to mass-produce than the Mark 6, with small solar panels on the back for limited operation. It is compatible with Mark 6 components.
· The final form of the Mark 7, the Mark 8, features a high gorget for neck protection and fully enclosed chest cabling, making it the most common Power Armour in the Imperium even 10,000 years later.

· Mark 10 Tacticus: Commissioned by Guilliman for the Primaris Space Marines after the Horus Heresy. Designed for the enhanced physiology of the Primaris, it uses a fibrous sub-layer that replicates natural muscle movement via the Black Carapace implant. All components are internally integrated and modular for easy maintenance. It combines the agility of the classic Mark 5 Maximus with the protection of the Mark 8 Errant, featuring state-of-the-art auto-senses and a nuclear power pack.
· Mark 10 Phobos: A lightweight version designed by Belisarius Cawl for stealth missions. Its thin ceramite armour and quiet servo-motors allow for stealthy movement, and its helmet, equipped with long-range sensors and thermal imaging, is specialized for infiltration and ambushes.
· Mark 10 Gravis: The heaviest configuration of the Mark 10 system, designed for Primaris Marines who 'never take a step back.' It's like a mobile tank with multi-layered reinforced ceramite armour and additional cooling systems, used by units like Inceptors equipped with heavy weapons or jump packs.
· Mark 10 Omnis: A hybrid form combining the protection of Gravis and the mobility of Phobos, developed for Suppressor squads. It excels in capturing high ground or rapid redeployment, carrying jump packs and heavy weapons while maintaining excellent maneuverability.

· Also known as Tactical Dreadnought Armour, it began as an ambitious project to replace all standard Power Armour. Combining industrial exoskeletons and combat technology, it's a 'wearable tank' capable of withstanding impacts that would shatter ordinary soldiers.
· Cataphractii Pattern: Set the standard for durability during the Great Crusade, characterized by unique shoulder pauldrons housing capacitors for displacement shields.
· Tartaros Pattern: Focused on agility, using Mark 5 neural links that allowed the wearer to rotate their head freely.
· Saturnine Pattern: Equipped with powerful plasma cannons, but only a few survived the chaos of the rebellion.
· Invictus Pattern: The current standard model, easily identified by the Crux Terminatus on the left shoulder pauldron.
· Other specialized variants exist, including the Iron Hands' Gorgon Plate, the Grey Knights' Aegis Armour, and the Arcana Pattern.

· Unique, handcrafted masterpieces embodying the spirit of each Chapter, crafted for elite commanders and legendary veterans.
· Made from ultra-dense materials reinforced with rare alloys and complex micro-structures, it offers protection comparable to Terminator Armour while maintaining agility.
· Some are specialized versions integrating machine interfaces and servo-tools, with histories dating back to the Great Crusade or even the Dark Age of Technology. Repairs and battle scars become part of the armour, passed down through generations.

· Specialized gear used by the warriors of Fenris, combining advanced engineering with ancient Viking-style mysticism.
· Also known as 'Ethereal Rune Armour,' it acts like a magnet, absorbing and nullifying psychic attacks. The Adeptus Mechanicus of Mars calls it 'Rune-Pattern Mark 12,' claiming it's due to induction circuits hidden within the metal.
· The Space Wolves believe in the power of the runes inscribed on its surface, each made from the bone or teeth of Fenrisian beasts and imbued with specific intent. It is said to protect the soul from the Warp, and rare, millennia-old suits are bestowed only upon the Chapter's bravest warriors.

· Discovered as an STC template during efforts to recover lost technology in the 36th millennium. It's a massive exoskeleton worn over existing plate armour, turning a Space Marine into a 'walking fortress' specialized for siege warfare.
· Connected to the machine spirit via cables on its back, it can experience synchronization delays as it bypasses the Black Carapace. Primarily used by Devastator and Assault specialists who prioritize overwhelming firepower.
· It has its own power source, is larger than Terminator Armour, and uses damping fields to absorb the recoil of tank-like weaponry. The Assault variant functions as a siege drill capable of breaching steel walls, while the Devastator variant serves as a mobile heavy weapons platform.
