Catachan was colonised by Humans millennia ago during the Dark Age of Technology, long before the Imperium of Man was established. A knife is not only a tool and the weapon of a Catachan warrior but also a mark of his status. The steel alloy used for these knives is only found on the jungle planet of Catachan. A well-honed Catachan blade will not rust and its edge will remain keen even after continuous use. https://www.warhammer-community.com/2020/03/01/sunday-preview-star-lizards-and-start-collecting-boxes/ The Catachan Devil Claw MK IV is unique from the other weapons as the in-game description and lore of the armament states that it is “Named after the Catachan Devil, a fearsome predator from the Catachan jungles, this massive blade is the most prized weapon of the eponymous regiment.” Buildings must constantly be rebuilt, for it seems that wherever the people of Catachan build structures, the jungle redoubles its efforts to destroy them.

The colonists only barely survived, holed up in their spacecraft against a living, besieging jungle, a battle for survival in which undoubtedly many of them died before they finally managed to learn enough about their new homeworld to survive, if not thrive, beneath its jungle canopies. In Catachan regiments, these elite soldiers are called "Catachan Devils," in reference to their famous Catachan Knives and the voracious predators of their homeworld whose fierceness they emulate in combat. Arandra V (930.M41) - The Catachan XXIV Regiment, the "Waiting Death," destroys WAAAGH! Krakskull on Arandra V, luring the entire Greenskin horde into a booby-trapped ravine with "Baiter Squads."The front legs of older male Devils become grossly enlarged, resembling scorpion claws. These mighty beasts are often dubbed ' Fiddlers' in Catachan slang, and are quite rightly feared for their ferocity and raw power, being the deadliest of their kind. The head of Catachan Devil is small and pointed with green luminous eyes. [3] [5]

Even these tough and uncompromising officers are unable to assert their authority over Catachan soldiers, who are notoriously disrespectful to any who have not shared the perils of their homeworld; in fact, Commissars are generally deeply resented by these troops, and it is not uncommon for Commissars assigned to Catachan regiments to be "fragged" by their own men. It is common for Ogryns, however, to fight in Catachan regiments. Shredder Mines - Explosive fragmentation charges mounted on an upright plate hurls the blast in a specific direction, creating an expanding cone of destruction filled with white-hot fragments of metal. Shredder Mines are Ideal for covering trails, streams and paths. Common mines of the Shredder type include: Triplex Phall Type XII "Repudiator" auto-mine, Armageddon "Hammerhead" area denial weapon, and the Necromunda Pattern "Widowmaker" anti-personal savager. Captain Catachan - A legendary Catachan Devil who is used for propaganda purposes by the the Astra Militarum's Regimental Standard newspaper. The Brainleaf, a vegetative carnivore, is a small tree, not particularly conspicuous on Catachan, but is able to attach its tendrils to the spine and brain of a person, taking control over their body. This creature may be an offshoot of the Tyranid Cortex Leech, a creature with similar abilities. [18]Spring Mines - Spring Mines received this moniker because these devices spring into the air before detonating. Spring Mines are particularly effective against dispersed targets. However, a wary squad leader will advance with a trooper moving ahead on "point" to try to reduce the effectiveness of Spring Mines. Common mines of the Spring type include: Necromunda Pattern "Jumping-snap" anti-personnel leaper, the Gearian Type XIV vertical blast device, and the Martian Type CXI Fragmentation Mine. Fire Support Heavy Weapons Squads - Compared to a standard Imperial Guard force, Catachan Heavy Weapons Squads are rare. The weapons' bulk and the weight of their ammunition makes them difficult to transport across a wilderness as unforgiving as the jungle environments where the Catachan Regiments see most of their combat. Nonetheless, the firepower of Heavy Bolters and Autocannons can be decisive in close battles. These squads are composed of one and three Heavy Weapons Teams, each consisting of two Catachan Veteran Guardsmen.
