Catachan Jungle Fighters: Warhammer 40K Lore Guide

On Catachan, everything wants you dead. The trees strangle, the leaves poison, the insects carry diseases that rot flesh from a scratch, and the predators are big enough to tear a tank apart. Half of all children die before they can walk, and half of those who remain do not see their tenth birthday. The ones who survive grow up to be the most dangerous light infantry in the Imperium, and they regard the rest of the galaxy's battlefields as a holiday.

The Catachan Jungle Fighters are the toughest of the Astra Militarum regiments, a red-bandanna'd army of guerrillas, trappers and knife fighters who win by ambush and infiltration rather than by drill. This guide goes beyond our Imperial Guard overview to cover the death world that made them, their tribal culture, their weapons and tactics, legends like Colonel "Iron Hand" Straken and Sly Marbo, their great campaigns, and how the army plays and collects.

Catachan Jungle Fighters at a Glance

Catachan: The Deadliest Death World

The Imperium classes a handful of planets as death worlds, places where survival itself is a daily war. Catachan is the most infamous of them all. Its jungle seems consciously hostile to foreign life: every animal is carnivorous, nearly every plant is poisonous, and necrotic bacteria can turn the slightest scratch fatal. It is said that even Space Marines avoid the place, and the planet needs no Planetary Defense Force, because no invader would survive long enough to fight one.

The lore has given Catachan a whole bestiary. The Catachan Devil is a monstrous many-legged predator big enough to give its name to the planet's most famous units. The Brainleaf is a parasitic plant that takes over its victim's nervous system. There are face-eaters, lethally toxic barking toads, stranglevines, spiker plants, blood wasps, venus mantraps and things the Imperium has never bothered to catalog. Humans on Catachan live in fortified settlements surrounded by cleared ground to keep fields of fire open, and even these do not last: vines, lichen and acidic sap eat through mortar and armor, and sooner or later the wildlife drives the settlers out to build somewhere else.

Children on Catachan learn to shoot before they learn to walk and are deadly fighters by the age at which children on other worlds learn to spell. Adults are heavily muscled, physically and mentally resilient, and blunt to the point of rudeness. Other Guardsmen have nicknamed them "baby Ogryns", though rarely to their faces. When the Departmento Munitorum calls a Founding, Catachans answer eagerly, because no war in the galaxy is harder than an ordinary day at home.

Culture: Family, Bandannas and Elected Officers

Catachan regiments keep the tribal structure of their homeworld. A regiment is often raised from a small region, so a squad might be made up of cousins, siblings and the uncles or grandfathers who lead them. That gives Catachan units a level of trust and teamwork drill-ground regiments cannot match.

It also gives them a unique relationship with authority. Catachans choose their own leaders. Captains and sergeants are elected, and if the soldiers decide a superior is unfit to command or is endangering the squad, they may openly challenge him to step down. A Catachan officer stays in charge exactly as long as he deserves to be.

Commissars, who expect to be obeyed, have a hard time of it. They have little real authority over Catachan troops, and it is an open secret that commissars attached to Catachan regiments sometimes go missing in the jungle. Commissars, for their part, admit that Catachans are born killers; they just do not respect them.

The rest of Catachan culture is visible on the soldiers themselves:

• The red bandanna symbolizes a blood oath, and it has become the regiment's emblem across the galaxy.
• Tattoos take the place of medals, recording years of service and marksman status.
• Trophies taken from the enemy are worn and traded for morale.
• A Catachan name, a nickname such as "Iron Hand" or "Stonetooth," is earned by junior soldiers through some memorable deed.
• Fatalism about the jungle. Catachans believe the jungle will take them all eventually. Dying in battle is simply another way of going home.

Weapons and Tactics of the Jungle Fighters

Catachans fight like the predators they grew up among. Their specialties are ambushes, long-range penetration raids deep behind enemy lines, booby traps and demolitions, and herding the enemy into terrain that will kill them. Their skills transfer easily from jungle to city, swamp or ash waste, and the old boast that one Catachan is worth ten soldiers from any other regiment is only partly a joke.

Their kit reflects that style:

• Light gear. Catachans prefer flakweave fatigues to heavy flak armor, and the shorter lascarbine to the full-length lasgun. Mobility matters more than protection.
• Knives. Every Catachan carries a Catachan fang, a knife up to twenty inches long used for fighting, survival and settling arguments. The blackened Night Reaper is used for silent kills. The Devil's Claw is closer to a sword at up to four feet long, with a hollow blade half-filled with mercury to add weight to every swing.
• Flamers and heavy bolters are the preferred special and heavy weapons. A flamer is the best way to clear dense vegetation, and the enemies hiding in it.
• Explosives. Demolition charges, mines and improvised bombs are standard, and some veterans could rig a jungle trail in their sleep.

Catachans also field specialists that other regiments would class as elite. Catachan Devils squads conduct deep raids, scout ahead and hunt enemy infiltrators. Veteran snipers lie hidden for days, sometimes using toxin-laced rounds. Assault teams of the most aggressive soldiers carry flamers, meltas and demolition charges. Catachans also work well with Ogryns, who appreciate a regiment that values strength and does not ask too many questions. Since nearly every Catachan who reaches the front is effectively a veteran, most regiments do not bother to distinguish them at all.

Legends of Catachan

Colonel "Iron Hand" Straken

The archetypal Catachan is Colonel Straken of the Catachan II. His nickname comes from the bionics that replaced the parts of his arm and chest devoured by a Miral land shark. His exploits are legendary even by Catachan standards: holding off a phalanx of daemon engines at Vendal's Landing with twenty-two men, ten lasguns and a case of short-fused mining charges; defeating the Drukhari Archon Yrekh Drash in single combat at the Battle of the Red Rain; leading the assault on Signis VIII and killing a Hive Tyrant; and waging a guerrilla war against the Orks on Dulma'lin, where he outfought the infamous Kommando Snikrot. In the current setting, Straken is overseeing the raising of a reconstituted Catachan II to fight in the Indomitus Crusade. Toby Frost's Black Library novel Straken tells his story.

Sly Marbo, the One-Man Army

If Straken is the Catachan ideal, Sly Marbo is the Catachan myth. A silent loner who appears from nowhere, kills everything and vanishes again, Marbo has been awarded the Star of Terra multiple times. The Imperial records credit him with vanishing for two weeks during the war against Waaagh! Urgok on Ryza and returning with the Warboss's head, being found alone on Galabad surrounded by wrecked vehicles and the Drukhari Archon's head on a spike, destroying a T'au armored convoy on Pardus by booby-trapping an entire ravine, and hunting chameleonic Lictors for sport. Several of his reported feats, including the destruction of a Gargant and a Titan, were dismissed as improbable or sealed by Segmentum Command. Marbo carries a toxin-coated blade so lethal that the smallest cut kills. It was also Marbo who carried Straken's broken body from the field on Dulma'lin.

Other heroes

• Gunnery Sergeant "Stonetooth" Harker — a heavy weapons specialist who reportedly killed a Tyranid Ravener by crushing its neck between his biceps.
• Colonel Greiss — Straken's predecessor in command of the Catachan II, later promoted to General.
• Sergeant "Ripper" Jackson and Colonel "Death" Strike — further names from Catachan's long roll of nicknamed legends.

Notable Campaigns

Catachans fight wherever the terrain is too hostile for anyone else. They took part in the Macharian Crusade, the Third War for Armageddon and the Pandorax Campaign, and they are a fixture of the Tyrannic Wars, where their skill at hunting predators in dense terrain makes them ideal against the Tyranid hive fleets. More recently they fought in the War of Beasts on Vigilus, the Season of Blood and the Fourth War for Armageddon.

The most telling story is the Battle of Catachan itself. When the Great Rift opened and the Noctis Aeterna cut the Imperium off from the Astronomican, Catachan was caught in a daemonic invasion. By the time Guilliman's Indomitus Crusade arrived to relieve the planet, the local Catachan regiments had already dealt with the threat.

How Catachans Differ From the Rest of the Guard

• Doctrine. Most of the Guard fights as a hammer: massed lines, tanks and artillery. Catachans are a knife, small units operating independently, often far ahead of any support.
• Discipline. Cadians are drilled professionals and Krieg obeys to the point of self-destruction. Catachans obey leaders they respect and ignore the rest.
• Individuality. Where Krieg erases names, Catachan collects nicknames, tattoos and trophies. Personality is part of the regiment's strength.
• Survival. Krieg wants to die and Cadia wants to hold. Catachan wants to win and walk out of the jungle afterward.

Collecting and Playing Catachans

The plastic Catachan Jungle Fighters squad has been part of the Imperial Guard range for more than two decades. Its bare-armed, bandanna-wearing troopers are a deliberate homage to 1980s action movies, and characters like Straken and Marbo carry that tone into the army. Catachan heavy weapons teams, flamers and Ogryns all fit the theme naturally.

On the tabletop, a Catachan force plays as an aggressive infantry army. Expect to use cover and terrain heavily, push into close range where flamers and knives do their work, and lean on characters who make the soldiers around them hit harder. Where a Cadian list sits back and shoots, a Catachan list goes looking for a fight. For painters, deep jungle bases, camouflage fatigues and skin tones carry most of the look, and the models reward a bit of grime.
