I made a visit to Warhammer World in June 2025. One of the displays at Warhammer World was this Horus Heresy battle, entitled, The Fall Of Outpost Sigma-12.
Traitor forces breach the Imperial Fist’s last defensive lines at Outpost Sigma-12 on Cthonia. Undermined by the Sons of Horus’ subterranean onslaught, the Loyalists are determined to fight to the last in the name of the Emperor. They ultimately reap such a toll of Traitor lives that any victory won was a hollow one. This battle would be one of the last fought during the Horus Heresy, for shortly after its bloody conclusion Horus launched his assault on the Emperor’s Palace on distant Terra.
I recently blogged about the Sons of Horus miniatures in that display. On my most recent visit to Warhammer World, I took some more photographs of the display.

This Imperial Fists Arquitor Bombard with Spicula Rocket System was in the displays at Warhammer World.
The Legion Arquitor is a heavy artillery platform designed to operate at the forefront of a Legiones Astartes advance. Equipped with a reinforced chassis and brutal short range firepower, it is called upon to break the most stubborn of fortifications or to annihilate massed enemy infantry and armour.
The spicula rocket system fires rippling salvos of unguided missiles that crash down on enemy positions, creating massive cumulative blasts that can scatter whole formations.
There are many different Armoured Vehicles of the Imperial Fists at Warhammer World.
The Rhino, or more formally, the Mars Pattern Rhino, is an Imperial armoured personnel carrier (APC) that is widely used throughout the galaxy by many different factions, though it is a mainstay vehicle of the Adeptus Astartes. It has provided safe transportation since the days of the Great Crusade, transporting its cargo of Space Marines swiftly and safely to the forefront of battle.
The Repulsor is an Imperial anti-gravitic main battle tank intended to provide armoured support for the Primaris Space Marines of many different Chapters.
The Repulsor armoured transport is a deadly combination of manoeuvrability and raw brute force.
Due to the turbine array at its rear, it has tremendous motive power, held aloft by powerful anti-gravitic generators.
The Repulsor is so heavily armed and armoured that is doesn’t skim over the landscape but instead crushes the ground below it.
The Astraeus is a symbol of the Imperium’s might, unbowed by the dawning of a bloody new millennium and unbroken by the onslaught of its foes. The Astraeus is a super-heavy tank, similar in form to the smaller Repulsor transport in use by the newly created Primaris Space Marines.
The Land Raider is regarded by many as the finest armoured fighting vehicle of its class in the Imperium’s arsenal, and is the mainstay battle tank of the Space Marine Legions.
It is a phenomenally powerful war machine, its multi-layered composite armour and reinforced hull all but impervious to even heavy weapons, being a sealed unit designed to resist enemy attack from any approach.
Intended to serve in almost any environment as both war machine and exploration vehicle, it can operate freely in war zones ranging from acid swamps to rad-deserts without any noticeable impediment to its performance, and can even operate in hard vacuum, ensuring there is no open battlefield on which its armoured wrath cannot be unleashed.
This is an Ultramarines Land Raider Proteus.
Those of us who have been playing Warhammer 40K since it was first released will recognise this model. It is of course a new version of the original Land Raider that was released back in 1987 following the release of the 1st edition of Warhammer 40,000, Rogue Trader. Forge World released a resin version a fair few years ago, and since then, a plastic version of the kit has been released as part of The Horus Heresy range.
This World Eaters Deimos Pattern Rhino was on display at Warhammer World.
World Eaters Deimos Pattern Rhino
The Deimos Pattern Rhino Armoured Personnel Carrier is a versatile and heavily armoured vehicle employed by both side of the Legiones Astartes during the Horus Heresy.
It is designed to transport troops safely into combat zones while providing them with substantial firepower.
Deimos Pattern Rhino
The Rhino’s thick armour and robust construction make it highly resistant to enemy fire, ensuring the protection of its occupants. Equipped with a variety of weapons, including heavy bolters and lascannons, the Rhino is capable of engaging infantry and light vehicles with devastating effect.
Ultramarines Deimos Pattern Rhino
The vehicle’s spacious interior can accommodate a squad of Space Marines, along with their equipment and supplies. The Deimos Pattern Rhino is a reliable and durable workhorse, capable of operating in the most challenging environments.
Sky-hunters are feared strike units, mounted atop sophisticated and powerful jetbikes.
Imperial Fists Sky-Hunter Jetbikes
These high-speed craft are more akin to compact aircraft than ground bikes – propelled across the battlefield by jet engines with grav-impellor assistance, they can maintain great speeds for extended periods of low-altitude flight.
Imperial Fists Sky-Hunter Jetbikes
The jetbike’s lift-strength is enough to carry an armoured Space Marine and his wargear along with a variety of heavy weapons mounts and stocks of ammunition, giving the Sky-hunters access to extremely potent, highly mobile firepower.
The Mastodon was one of the heaviest assault transports in the arsenal of the Legiones Astartes during the Great Crusade, and is still found in the armouries of the Space Marine Chapters of the 41st Millenium.
Mastodon Heavy Assault Transport
Its cavernous assault bay, capable of housing almost half a Company, is protected both by thick layers of ceramite armour as well as crackling void shields.
Mastodon Heavy Assault Transport
It also mounts a fearsome siege melta array, allowing it to breach even the most formidable defences with ease, as well as an array of secondary weaponry intended to defend the vehicle as it approaches its target.
Unleashed only against the most fearsome of enemy redoubts, there are few obstacles that can stay the wrath of this relic of the Imperium’s bloody birth.
Mastodon Heavy Assault Transport
The Mastodon is heavily armed and armoured, carrying 40 Space Marines, and even Dreadnoughts, safely to the heart of battle.
Mastodon Heavy Assault Transport
Whilst embarked, the warriors within will defend their immense transport, turning the sponson weapons on any enemy brave or foolish enough to come close.
Mastodon Heavy Assault Transport
It’s Siege melta array can easily destroy fortifications, and makes short work of armoured vehicles, whilst its Skyreaper Battery will tear through any airborne threat with ease.
The Fellblade Super Heavy Tank is a behemoth of the Legiones Astartes, a testament to their unwavering resolve and technological prowess. This imposing war machine is a towering fortress on tracks, its hull clad in thick, nigh-impenetrable armour that can shrug off even the most devastating artillery strikes. Its main armament is a devastating twin-linked siege cannon, capable of hurling massive shells with enough force to obliterate entire squads of infantry or even lighter vehicles in a single salvo.
Sons of Horus Fellblade Super Heavy Tank
To complement its firepower, the Fellblade is also equipped with a battery of heavy bolters and a pair of twin-linked lascannons, providing devastating anti-infantry and anti-vehicle capabilities. The Fellblade’s crew is protected by a multi-layered armour system and a reinforced cockpit, ensuring their survival even in the most intense combat.
Sons of Horus Fellblade Super Heavy Tank
This formidable war machine is a symbol of the Legiones Astartes’ relentless pursuit of dominance, a testament to their unwavering loyalty to the Emperor and their unwavering dedication to the cause of the Imperium. Then again, it is also a symbol of those Legions which betrayed the emperor.
Imperial Fists Fellblade Super Heavy Tank
The Fellblade is basedupon the same STC data as the Baneblade super-heavy tank, which is extensively used by the Imperial Guard. The Fellblade is a more advanced variant that first saw widespread service with the Legiones Astartes in the last decades of the Great Crusade.
Imperial Fists Fellblade Super Heavy Tank
It is most noted for its use of Mechanicum atomantic arc-reactor technology and a reinforced metaplas alloy chassis superior with an advanced accelerator cannon as its primary armament.These systems are Dark Age technologies rediscovered and restored to humanity shortly before the nightmare of the Great Heresy.
