Editing Warhammer 40,000 8th edition (section)

====[[Astra Militarum]]====
* A Militarum Regimentum is the Administratum term for all Regiments derived from a single planet. 
* Brief overviews of a bunch of minor Regiments. The [[Tanith First (And Only)]] get a mention as well. New Regiments include:
**The Ventrillian Nobles, who "donate"part of their wealth to Munitorum officials and Rogue Traders to ensure they can be deployed to only the most glorious and adventure-filled warzones. They carry swords as well as lasguns and have a bunch of super-heavy tanks that they get from the AdMech in exchange for the rare gemstones only found on Ventrillia.
**The Miasman Redcowls, flamer specialists native to the orbital station above the gas giant Miasma XVI. They're most often deployed on the front lines, partly to burn a path forward for their allies and partly because said allies find that the smell of their world's gases is intolerable.
**The Indigan Praefects, expert beast hunters who learned how to fight big nasty monsters after their planetary governor's prized collection of dangerous predators from across the [[Segmentum]] escaped to breed in the wild. Since then, they've become some of the Guard's best Tyranid fighters. 
=====[[Cadia|Cadian Shock Troopers]]=====
*After the fall of their homeworld, those who survived the battle then reinforced the other worlds within the Cadian Gate and manage to hold back the tide of Daemons and Traitor Marines when the great rift appeared.
*The Cadians' new motto after the fall is "Cadia stands!", in honor of the heroic sacrifice of [[Creed|their Lord Castellan]] and the Cadian regiments that gave their lives to hold off Abaddon's forces over the history of the Imperium. When you think about it, it's a pretty good war cry because Abaddon spent a good while brooding over his epic failure to conclusively beat and humiliate the Imperium on Cadia in a straight battle and each Cadian war cry is no doubt an irritating taunt. Creed's true fate remains unknown to the Imperium, though he is currently presumed dead. 
*The Cadians who survived the fall of Cadia, were unable to reach the defense of their homeworld in time, or were busy on a different warzone settled down/drilled  countless worlds to instill their martial prowess and proud traditions to their host planets in order to carry on Cadia's legacy. Even though Cadia has fallen, the Cadian Shock Troopers aren't going anywhere. So Abaddon in typical fashion snatched defeat from the jaws of victory by turning his Cadia problem into many many problems.
*Due to his involvement in the Damocles Gulf Crusade against the T'au at the time, [[Knight Commander Pask|Knight Commander Pask]] was unable to reach Cadia before it fell. Pask was ashamed and wept manly tears when he learned about the fate of his homeworld. He wished he could have fought and died honorably with its proud defenders, then he turned said shame into hatred of the forces of Chaos.

=====[[Catachan Jungle Fighters]]=====
*Despite being a proverbial stone's throw away from the Great Rift, Catachan not only avoided being corrupted by Chaos, but was able to hold its own against the daemonic hordes thanks to a combination of the Jungle Fighters' prowess and the inherent lethality of the native flora and fauna.
**By the time the Indomitus Crusade arrived, the forces of Chaos had already been driven off- it's noted that when the Crusade left Catachan, its forces were greatly swelled by volunteers from the Catachan Jungle Fighters.
*According to a story that's made its rounds around the Jungle Fighters, [[Gunnery Sergeant "Stonetooth" Harker|Gunnery Sergeant Harker]] first picked up Payback when he was a new recruit. His platoon had been sent to deal with a small band of Orks which turned out to be a Blood Axes ambush; when his lasgun's energy cells fried from overuse he claimed the heavy bolter from the remains of the platoon's heavy weapons squad. Harker was the sole survivor.

=====[[Armageddon Steel Legion]]=====
*As mentioned previously, the Third War for Armageddon has been complicated further by the appearance of the forces of Khorne and Tzeentch. Reinforcements are slowly returning, but the influence of Chaos remains a dangerous wild card in the continuing Imperium-Ork conflict.

=====[[Vostroyan Firstborn]]=====
*The Vostroyan Firstborn still uphold their tradition of reinforcing the regiments outside of Vostroya's territory to the best of their abilities. Unfortunately, they're on the side of the Great Rift where the Astronomican isn't visible, which means that many of the transports they send never reach their destinations. The Vostroyans keep sending transports anyway, hell-bent on ''never'' repeating their refusal to send aid during the Horus Heresy.

=====[[Valhallan Ice Warriors]]=====
*Valhalla was surprisingly able to keep on with business as usual through the Noctis Aeterna, with the sheer stubbornness of the Valhallan Ice Warriors seeing them through the disappearance of a coherent chain of command.
*With the aid of the nearby Hive World of Skovi, the Valhallans drive off a major Ork fleet before it can reach Valhalla. While the losses are predictably staggering, it is still a victory.

=====[[Tallarn Desert Raiders]]=====
*The Tallarn Desert Raiders have recently taken up guerrilla tactics, acting as diversionary forces working in conjunction with other parts of the Indomitus Crusade. Additionally, their vaunted mobility has allowed them to thrive even as other regiments are strained by Warp storm-related logistics issues.
*A detachment of Tallarn Desert Raiders aided the Grey Knights in battling the rotten hordes spawned by the sentient plague Eater of Lives. As a show of gratitude, the Grey Knights carve the names of the Tallarn commanders into their armor...[[Grimdark|before euthanizing the lot of them, just to be safe]].

=====[[Mordian Iron Guard]]=====
*When the Thousand Sons and Tzeentch's Daemons attacked the Stygius Sector (where Mordian is located), Mordian alone was able to drive off the forces of the Architect of Fate. They remain ready for the inevitable next assault, aided by the Iron Hands after they refused to retreat from the sector.
