Here's my finished predator, with a fluff piece about it, enjoy.

Kratorum-Minos Pattern Legion Predator.

A variant of the standard Legion pattern Predator Battle Tank family of weapon systems, the Kratorum-Minos was predominantly used by Traitor forces during the Horus Heresy, mainly the XVI Legiones Astartes "Sons of Horus". This was mainly in part due to the design and championing of the project being done by Forge Master Vehdrek Faine of the XVI Legion.

Principally constructed on the minor Forge World of Kerrex and within the fleets of the Sons of Horus, the Kratorum-Minos is for all intents and purposes, a jury rig. Utilising parts and systems from various other Legion vehicles to aid in part compatibility in minor echo of the vaunted STC patterns. Forge Master Faine was enamoured with the idea of logistics, having spent a fair amount of deployments fighting alongside the XIIIth Legion, and meeting with their Primarch on a handful of occasions. Faine has remarked that Guilliman's greatest shame is not following Horus into his rebellion, as the addition of the XIIIth legion's numbers and logistics would have ended the war before a shot was fired.

Faine had no doubt that the Warrior Pride of the XVIth was unmatched, and was sure that the Sons of Horus could defeat any foe in 1 to 1 combat. However, the Galactic war his gene-father had envisioned was beyond any challenge the Imperium's premier Legion had faced before.

In the aftermath of Istvaan V, Faine was set the task of swelling the ranks of the Sons of Horus companies under his care with fresh war hulls for their fleet of armoured vehicles, scrounging from the fallen at the Urgal Depression, and from newly compliant worlds in the galactic neighbourhood of Istvaan.

Upon seeing so many legion variants filling the holds of the XVI's warships, Faine was struck by a need for standardisation, and uniformity. So now at odds with the individualist Legion culture that had burgeoned within the Sons of Horus, already prevalent with the Cthonian ganger fraternities; now blossoming to near tribalism with Horus at the Apex, a Lord above his chieftains.

After consultation with the agents of the new mechanicum, and The Twisted, Faine and his closest council if Techmarines were sent to the minor Forge World of Kerrex. Where he was to begin production of a new Legion predator, to become the standard within the XVI, and later the New Imperium. He was given access to all the forbidden rites of machine-lore the dark mechanicum could provide him with.

Falling back on previous Legion designs, mainly the Sicaran Battle Tank and Kratos Heavy Tank, the Kratorum-Minos was made almost in blissfully subtle mimicry of both. While still retaining the size and composition of the Mars Pattern Rhinos. A new feature was the retractable shutter doors, behind the side sponson guns that would allow the reloading of sponson guns mid battle by servo automata within the crew compartment.

The tank's sensor suite was upgraded as well, with improved optics and threat auspex, as well as an improved comms array that could function effectively in the scrapcode choked battlefields of the heresy. Command variants were given a uplink to the Noosphere, and various strategic functions which allowed a Commander of Kratorum-Minos pattern Predator higher levels of battlefield awareness than the average Predator tank.

All variants were tested, and all weapons that could be mounted to a base Predator tank, could be fitted to a Kratorum-Minos. Faine had a affection for the standard model, outfitted with a Predator Cannon, and for the Predator Interitus variant, outfitted with the deadly Heavy Conversion beamer.

The Vehicle went into production in the Forge vessels of the Sons of Horus fleet as well as Factorum of Kerrex, a year before the battle of Beta Garmon. This "limited" run however were a drop in the bucket compared to the masses of Mars and Deimos pattern hulls being churned out by Imperial worlds loyal to the Warmaster. As such only several companies were completely outfitted with them by the time of the Siege of Terra, and very few survived that apocalyptic conflict.

Additionally after the Death of Horus and the beginning of the Scouring, Kerrex and its system were purged for their loyalty to the Arch Traitor. Elements of the XVI tried to regroup there and rearm and were caught by Fleets of the VIth and XIIIth legions and supporting Imperial forces. Faine was killed there, as were all the Magi of Kerrex.

Kommenkos waited, the engine of his Predator ran idle creating a low-level noise that his enhanced senses blocked out. Staring out of the vision ports of the cupola of the turret he watched the ruins before him, waiting for the Imperial Ar-... Imperial Guard armoured patrol to roll past. Scout-cultists had said that a Salamander Command Vehicle and Two Chimera APCs come past this point at least three times a day.

He had chosen perfectly, parking his vehicle mostly within a terraced housing structure, as if it had suddenly diverted into it to escape an attack and then had been disabled. He then prepared his ambush further by taking down any walls or fencing that would impair his field of vision and field of fire. Being a former member of the Iron Warriors, he knew how to keep a structure standing whilst also breaking it apart.

Looking around, the last echoes of humanity within him stirred, this was once a home. Noticing a little pictograph on a wall, damaged now. The glass was cracked over one of the adults in such a manner to obscure them, the other a woman with a beaming smile, in front of them two children. One small boy with a mischievous grin and one girl. Dark brown hair, blue eyes.

'Kommen', he heard a voice distantly say within his mind, 'Kommen'. A memory surged into his mind, a memory from a time before his superhuman form, back on Olympia, he was young then. He was outside the walls of Lochos, in the fields below them, under a tree chasing a girl. A sonic boom overhead caused him to slow, he looks up to see two Lightning Strike Fighters fly overhead. He looks back at the girl who is stood before him now, she says 'Kommen', he reaches out to say something but the words are replaced by muffled noises, she smiles opens her mouth as if speaking but his memory has forgotten what was said. But the memory of emotion is still there, joy and sadness intertwined. She cries, her blue eyes pierce his mind and her name 'Fydiaz' is the only thing he remembers saying. Then pain, memories of combat training, implantation, surgeries, indoctrination swallow his mind and bring him back. Lochos burns in his mind, their rebellion failed. Perturabo decimated and enslaved the population, those who resisted were killed. He remembers finding Fydiaz, in a home like the one he is stood in now. She is dead, alone, but in her hand she holds a picture of a younger version of her and a boy, with a little 'IV' emblem in the corner. He remembers his dread realisation, the boy is him. She never forgot about him, both his hearts sank. That was the day he ceased to serve Perturabo.

He snapped back to the present, turned around and got back into his tank. The Hellwrights had bound the souls of his former crew to the machine spirit, enabling it to perform almost autonomously, which allowed Kommenkos to fight and hunt alone. Firing the weapons was as simple as thinking about it as his bionics allowed him to be directly wired to his vehicles with the views from the sights on the weapons were lit up on hololithic displays for him to see.

He saw the three vehicles approach and angled his weapons accordingly, the lascannons ruined the front and rear vehicles of the patrol with the latter vehicle, a Chimera, exploding in a ball of flame. The Predator Autocannon tore into the remaining vehicle, the other Chimera, taking a set of tracks out and disabling the turret. As the rear hatch opened, guardsmen charging out, Kommenkos fired the havoc missiles. They screamed through the air and detonated on the doomed troopers, shredding many of them. He opened up with the Autocannon again, finalising the destruction of the Chimera and ending the survivors.

Kommenkos surveyed his battlezone, the guardsmen were dead or dying, three vehicles taken out, they didn't have time to react. He closed his eyes, allowing himself to try to remember Fydiaz once more. His training had removed all the other memories of his previous life, his life as a child, before the Ascension. He tried in vain to recall her face, but all he could see was her dark hair and those piercing blue eyes. His brain tried to search for an emotion that wasn't there anymore, just anger and bitterness remain.

Siege Assault Vanguard

Refitted to the exacting standards of the IV Legion, the Olympia-pattern Vanguard Siege Assault IFV (more colloquially known as the Siege Rhino) was an offensive-focused cousin to the more ubiquitous Castellan-pattern, built to force breaches and manoeuvre squads into heavily defended positions. Favoured by specialist veteran squads such as Aigaion and Kottos who made heavy use of the vehicle, the Vanguard was well loved for its rugged construction and dependability.

Fitted with a ramming glacis, storm armour, driver’s periscope, and a pintle-mounted multi-melta, Vanguards lacked the side doors and top hatch of a standard RH1-N0 APC, which were replaced with ablative plates. Vanguards also came equipped with a tow crane, capable of hauling a vehicle of its own mass thanks to its dedicated engine (visible on the roof), and some variants were fitted with heavy clearance dozers for further use as battlefield support tanks. Vanguards were cramped and noisy vehicles at the best of times thanks to their overclocked engines and reinforced structure, though this general lack of comfort mattered little to posthuman troops.
