Weapons of the Imperium

This list names the various types of weaponry used by the Imperium in the Warhammer 40,000 universe. The various weapons, grouped according to their category, are discussed in detail including their in-universe specs and their in-game use. With the evolution of the Warhammer 40,000 setting over some 20 years, many weapons and equipment have been described in the various editions of the various games. Some of these are no longer in use in the most current editions. Whenever appropriate, the history of the weapon in-game is described, including some of the more notable units that are known to carry that weapon.

The Imperium is a vast, galaxy-spanning empire in Games Workshop's Warhammer 40,000 fictional universe. There are several armed branches of the Imperium's military and police services, and much of their equipment is common to multiple branches. The armed forces of the Imperium include, but are not limited to the Space Marines, the Imperial Guard, the Adeptus Mechanicus, the three Ordos of the Inquisition, the Adeptus Arbites and the Orders Militant of the Sisters of Battle.

The information below is taken mainly from the Warhammer 40,000 rulebooks, and the Warhammer 40,000 second edition wargear book. Some of the weapons descriptions are also supplemented by information from the first edition of the Necromunda rulebook, which contains detailed writeups on the various weapons in the Warhammer 40,000 universe. Specific weapon descriptions have been taken from their appropriate Codex entries, including the various Space Marine, Imperial Guard and Inquisition codices.

In addition, some of the descriptions of the weapon effects are taken from the Warhammer 40,000 video games, Dawn of War and its expansions.

Close-combat weapons
Close combat weapons are an entire class of single-handed weapons used in the Warhammer 40,000 tabletop game and universe. The term itself is a collective term for any implement or weapon that can be used one-handed in an assault. This includes various common melee weapons such as swords, knives, bayonets, maces, clubs and even pistols. It also includes some unorthodox "weapons" such as claws, tails, beaks and teeth.

Specific races have certain preferences for close-combat weapon types, as seen in the official miniatures released by Games Workshop for those races. The Space Marines make common use of chainswords. The Imperial Guard have knives and long machete-like blades in addition to the bayonets occasionally attached to their lasguns.

C'tan Phase Sword

 * Used exclusively by Callidus assassins, the C'tan Phase Sword is an extremely potent close-combat weapon. In the background, it is said to "phase" in and out of "realspace" and is capable of bypassing armour and force fields alike. This characteristic is reflected in-game by the Phase Sword's special rules, which prevent any kind of saving throw from being attempted against wounds caused by the sword.


 * It is suggested by the background information that the weapon itself has an inherent connection to the gods of the Necrons, the C'tan with which the weapon shares its name. In the third edition Necron codex, a story describes how a Callidus assassin stabs one of the disguised C'tan with her C'tan Phase Blade. Instead of being injured by the weapon, the C'tan simply reabsorbed it back into its body. This is actually reflected in-game by the Necron's special rules. In-game, a C'tan hit by a phase blade will absorb the weapon, disarming the offending attacker.

Chain weapons
A chain weapon is a weapon that has motorized biting teeth that saw and slash through a prospective victim, in a similar fashion to a chainsaw. The teeth themselves are fashioned to be incredibly sharp, in some cases carrying a monomolecular edge. Some chain weapons are capable of slicing through bulkheads and thick armour.

Chainfist

 * Other variations of the Chain Weapon are used all over the galaxy. Space Marine Terminators often replace their standard power fist with the chainfist for use against enemy armoured vehicles. The chainfist is a combination of a Powerfist and a Chainsword which usually protrudes from the back of the hand, just above the knuckles. This weapon is capable of cutting through even the toughest of armour on battle tanks. Chainfists are so massive and encumbering (limiting their effectiveness against enemy troops), not to mention energy-inefficient, that they are normally only ever seen on Space Marines equipped with Terminator Armour.

Chainsword

 * The most common form of chain weapon is the chainsword, frequently carried by assault troops and low-ranking officers of the Imperial Guard and Space Marines (including the Traitor Legions). Another common variant is the chain axe, which is usually carried by Chaos Space Marines (normally of the World Eaters Legion) known as Berzerkers of Khorne.

Eviscerator

 * A larger version of the chainsword known as the Eviscerator, is usually seen in the hands of religious fanatics such as penitent Sisters of Battle or the zealous and fiery Redemptionists, the Eviscerator is also another weapon used by Imperial Guard priests. Eviscerators closely resemble chainsaws, and being large two-handed weapons, are generally powerful enough to have similar effects to the chainfists frequently seen carried by Terminators.

Frost blade

 * A Frost blade or Frost axe is a specialised chain weapon used by some characters in the Space Wolves Chapter of Space Marines. The weapon itself is similar in look to a standard chainsword or chainaxe, except that the blade includes teeth from a creature called a kraken - one of the creatures that inhabit the Space Wolves' home world of Fenris in the army's background. In-game, the weapon acts more like a power weapon than a chain one, and is in fact minutely stronger than a standard power sword or axe.

Other chain weapons

 * Chain weapons are not just limited to swords and axes though. Existing in the galaxy are chain glaives as well as a multitude of other bladed weapons that have had their blades removed and replaced with the striking chain blade.

Hunting Lance
Use exclusively by the Rough Riders of the Imperial Guard, this is a lance tipped with a shaped explosive charge. It is a one-shot weapon used in close combat, allowing the guardsman to hit faster and stronger than normal. It also ignores armour, in a similar fashion to power weapons.

Power weapons
Power weapons, by comparison to regular weapons, utilise focused energy fields to increase the deadliness of the weapon, enabling it to pass through and penetrate armour with ease. Power weapons come in many forms, from the modification of a melee weapon such as a sword or axe, to the gigantic Powerfists (also known as Power Gloves) and Lightning Claws.

The weapon uses a generator that sheathes it in a bluish haze of disruptive energy. Long-forgotten technological marvels allowed the energy field of a power weapon to be generated on its own, creating a weapon similar to Star Wars' lightsaber. Common power weapons need a physical basis for the energy to be wrapped around. Then, the two components work together to become extremely effective at carving through enemy armour.

Neuro-Gauntlet

 * A type of power weapon used only by the Eversor Assassin temple, this is a glove consisting of many needles encased in energy fields. Bypassing any armour, the gauntlet affects the nervous system of the target, meaning the assassin can wound any individual, regardless of size and toughness.  It also has a limited effect on vehicles.

Thunder Hammer

 * A large hammer incorporating a power field generator, which instead of being active constantly (as is the case with other power weapons), builds up an immense charge which is then released in an instant upon impact with the target. The name comes from the thunderclap-like noise the weapon makes when striking. The force released is enough to knock over the wielder himself unless he is heavily armoured, which is why it is usually only carried by marines in Terminator armour. It is normally used in conjunction with a Storm Shield. It is as powerful as a Powerfist, but also has added effects against both vehicles and infantry.

Dreadnought close combat weapons
Some of the most powerful close combat weapons in the game are the huge Dreadnought close combat weapons (DCCW). They are more effective than an equivalent infantry power fist since dreadnoughts are unencumbered by the close combat weapons' weight. They are thus able to strike quickly, represented in-game by dreadnoughts striking in their initiative order.

Dreadnought close combat weapons are usually found on Space Marine Dreadnoughts. The Space Wolves Venerable Dreadnought Bjorn the Fell-Handed has a lightning claw as its dreadnought close combat weapon. In the past, separate rules covered this weapon, but with the simplification of the third edition ruleset, the lightning claw works the same as other DCCWs.

Force weapons
Force weapons are close-combat weapons designed to channel the psychic energies of the wielder, thus energising the weapon and augmenting its potency above and beyond that of even power weapons. They are used mainly by Space Marine Librarians, Grey Knights and Imperial Inquisitors. Force weapons vary in design, but usually take the form of a bladed weapon, most commonly a sword. Force staves are also common amongst Psykers in the Imperial Guard and is also the weapon of choice of Tigurius, Chief Librarian of the Ultramarines. Grey Knights, elite Space Marines from the Ordo Malleus, use force swords and force halberds exclusively. The weapons of the Grey Knights were known as Nemesis Force Weapons in the Space Hulk game, but here they were described as incorporating a storm bolter, a notion which appears to have been abandoned since. Force weapons are each unique in their own right, as each is psychically attuned to its owner and thus cannot be effectively wielded by anyone with a different psychic presence. As a general rule, a force weapon will use the psychic power of the user to push the target into the Immaterium, or "The Warp".

Bolt Weapons
Bolters fire explosive .75 calibre rocket-propelled rounds, and are similar in nature to the real-world Gyrojet. They are more sophisticated technology than lasguns or slug-throwers, and more powerful than equivalent sized weapons in either case so are given to the more deserving or capable (e.g: the Adepta Sororitas or the Astartes). Each round contains a mass-reactive explosive payload, triggered milliseconds after contact with a target. Bolters are made in pistol, rifle, machine gun-like heavy bolter, and gatling rotary cannon form. The Chaos Space Marine legions also retain the bolters issued to them prior to the Horus Heresy, as well as manufacturing new ones.

Boltgun

 * The standard weapon of the Adeptus Astartes, or Space Marines is the boltgun, also known as a bolter. A bolter fires semi-auto, three or four-round burst, or fully automatic fire, and typically carries twenty to thirty rounds in its standard sickle-shaped magazine.  Other magazine options include a fifteen-round straight magazine, a forty-round drum-magazine and a thirty-round belt feed.  The latter is very likely not restricted to a mere thirty rounds, but it and the drum-magazine are notoriously prone to malfunctions.  Bolters are more effective and more complex than the standard pattern lasgun, but are also different in that they are slugthrowers and so have incomparable operating conditions. Bolters are mainly used by the genetically engineered Space Marines, the Adepta Sororitas, and less frequently by Imperial Guard veterans and officers.


 * There are many variants of the bolter (referred to as Patterns); including the Ultima, Crusade, Heresy, Fillienostos, Nostra, Godwyn-Deaz, and Astartes Umbra patterns. Bolters are also highly customizable, and can be equipped with a wide variety of different modifications, such as optical scopes or bayonets. They can even be used as sniper weapons, especially when equipped with the Stalker silenced shells and the M40 Targeter system.

Combi weapons

 * Some bolters are customized so that they combine a bolter with a small version of another gun. This grants the wielder some flexibility as they can choose to fire normal bolter rounds or the more specialized side weapon.  These types of bolters are referred to as "combi-" weapons, with the name of the side weapon following- for example, a "combi-flamer" combines a bolter with a flamer.  While the bolter carries its normal complement of ammunition, the secondary weapon carries only limited ammunition and cannot be fired as often. A special Combi weapon, the Combi Bolter, does not use specialised rounds but fires extra shots to ensure the target is always hit. Combi Bolters are used by the Chaos legions as a substitute for the Storm Bolter, due to the latter being conceived after the Heresy, thus restricting access.

Bolt pistol

 * The bolt pistol is a common variant of the boltgun, and apart from the Space Marines, is also available to officers and seasoned veterans of the Imperial Guard- they are sometimes gifted to commissars, both for battling and field executions, leading to the weapon being nicknamed the "Bravery Bolter". A standard bolt pistol is capable of housing between 6 and 12 rounds of ammunition, and has a barrel diameter of .75 calibre.

Executioner pistol

 * Used exclusively by the Assassins of the Eversor temple, this is bolt pistol/needle pistol combi-weapon, but unlike other combi-weapons, the needle pistol part of the Executioner may be fired more than once per battle.

Heavy bolter

 * The heavy bolter is a support weapon. Unlike other bolter weapons, it is relatively common in Imperial Guard forces. It has a high rate of fire and long range, and they are relatively cheap to field. It is used on tanks and a variety of vehicles as an anti-personnel weapon as well as on fixed defences.


 * Due to its size and weight, Imperial Guard infantry operate using a two man team. A single Space Marine, being physically stronger, can carry both the heavy bolter and its ammunition alone. The Sisters of Battle, with their power armor enhanced strength, are also capable of carrying the heavy bolter and ammunition alone. It is also referred to as the "Back Breaker" or the "Bruiser".

Hurricane bolter

 * The Hurricane bolter is a weapon mount fitted to the Land Raider Crusader. An extremely effective anti-infantry weapon, it consists of three "twin-linked" bolters mounted as a single weapon system.

Mega bolter

 * The Vulcan mega-bolter is a super-heavy version of the bolter, mounted on Imperial Titans, most commonly the Warhound. It resembles two Gatling guns mounted on a large housing. Specialized "Vulcan Mega-Bolters" are sometimes used as the weapon on the chin turret of Imperial aero-space vessels.

Psycannons

 * The psycannon is a weapon created specifically to combat daemons. It is a more powerful version of the bolter, utilizing high-calibre psychically-charged ritually-inscribed silver-tipped psycannon bolts. The psychic charge and ritual inscription on every bolt allows it to pass through any defensive shielding, whether it is created by psychic energies or technology. The weapon has a suspensor to offset the weight and allows it to be fired on the move although at a cost of reduced effective range.


 * The Psycannon is a weapon used almost exclusively by the Ordo Malleus and its Order Militant, the Grey Knights Chapter of Space Marines. There are a few notable exceptions, such as Gideon Ravenor of the Ordo Xenos, whose armoured chair was fitted with a pair of such weapons.
 * The Psycannon is generally wielded with both hands by the normal power-armoured Grey Knights and most other operators, although members of the Terminator squads mount the psycannons on their arm instead. The method of feeding ammunition is similar to that of a heavy bolter, being an ammunition belt running from the ammunition store located within their backpack.


 * High-ranking members of the Ordo Malleus may use bolt guns which fire downsized version of the psycannon ammunition. These are less effective than the Psycannon but more powerful than the same sized bolt weapons.

Storm bolter

 * The storm bolter is a double-barreled version of the bolter. As it is designed for brutal assault, and consumes more ammunition than a normal bolter, they are not normally utilized by Space Marines in regular power armour. However, they are standard issue for Space Marine Terminators, and are often a tank's pintle-mounted weapon.  They are also used by the Grey Knights as a gauntlet-mounted weapon with its feed sourced from the back of their armour or from a magazine on the side of the gauntlet (as seen in Dawn of War: Dark Crusade).  Like boltguns, Imperial Guard veterans and officers rarely carry a storm bolter. The Sisters of Battle will sometimes designate a member of a squad to carry a storm bolter as a special weapon.


 * Due to high munitions consumption, and the lack of dexterity in Tactical Dreadnought Armor, most Storm Bolters are fed from a large box magazine, carrying approximately 100 rounds. When the weapon is used without Tactical Dreadnought Armour, it usually has a more conventional magazine containing sixty rounds, which, given the double barrels and firing mechanism, gives you thirty shots. These rounds are identical to those fired from bolt pistols and boltguns.


 * Before the Storm Bolter was created by the Tech Priests, Terminators were often equipped with special combi-weapons which were essentially two boltguns fused together. These "combi-bolters" were capable of a higher rate of fire than the Storm Bolter when at short range, but were less effective at longer range.  Combi-bolters have been replaced by Storm Bolters in Imperial armies, but are still frequently used by Chaos Space Marines.

Bolt Ammunition

 * The Tech-Priests of the Adeptus Mechanicus have developed many types of bolter ammunition over the millennia. The most common variants are:
 * Standard Bolts comprise the following components: Outer casing, propellant base, main charge, mass reactive detonator cap, depleted deuterium core, diamantine tip. The standard bolter shell is standardised at .75 calibre, whereas heavy bolter rounds are larger, at 1.00 Cal.
 * Hellfire Rounds have devastating results on organic matter, as the rounds are developed to combat Tyranids. The core and tip are replaced with a vial of mutagenic acid with thousands of needles that fire into target upon the shattering of the vial, pumping the acid into the target.
 * Stalker Silenced Shells are rounds with low sound signatures, meant for covert fighting and used in conjunction with an M40 targeting system and an extended barrel on a bolter to produce a sniping weapon system. A solidified mercury slug replaces the mass-reactive warhead for lethality at sub-sonic projectile speed. A gas cartridge also replaces both the propellant base and main charge for silent firing.
 * Inferno Bolts are designed to immolate their targets and destroy them with superheated chemical fire. The deuterium core is replaced with an oxy-phosphorus gel, known as Promethium. It should be noted that the Chaos Space Marine Thousand Sons have their own unrelated type of inferno bolts, which are actually psychically-bound slugs that release arcane energies; these slugs explode with sorcerous energies upon impact.
 * Ulysess Bolts are bolts which contain a tracking device. Fired into large objects, it will accurately report the target's relative position to a tracking device.
 * Metal Storm Frag Shells are best against multiple lightly-armoured targets. They detonate before impact and spray shrapnel, shredding their victims. A proximity detonator replaces the mass-reactive cap, and the diamantine tip and deuterium core are replaced with an increased charge and fragmentation casing. They are similar to flak rounds and are used against clusters of enemies.
 * Kraken Pattern Penetrator Rounds are powerful armour-piercing rounds. The deuterium core is replaced by a solid adamantine core and uses a heavier main charge. Upon impact, the outer casing peels away and the high velocity adamantium needle accelerates into the victim, where the larger detonator propels shards of super hardened metal further into the wound. These are effective against heavily-armoured infantry.
 * Psycannon Bolts are used by the Inquisition, primarily the Ordo Malleus and Grey Knights. They are very similar in nature to the rounds fired by their namesake, the Psycannon, and are similarly used against psychic and daemonic targets. Of all the rounds these are the most expensive, as each and every bolt is inscribed with runes on a microscopic level. Other sources say that they contain an anti-psychic substance that still others claim is a byproduct of the Emperor's Golden Throne. The psychic nature of these rounds are not only effective at destroying daemonic targets but also highly efficient at piercing the powerful barriers created by forcefield generators (such as the Tau Shield Generator and the Imperium's own Iron Halo and Storm Shield).

Flamers
Flamers are flamethrower-type weapons that project an ignited stream of promethium fuel over a wide area, igniting many enemies in a single gout of flame. In-game, they are represented by using various teardrop-shaped templates that represent the extent of the weapon's effect on the battlefield. Much like their real-life counterparts, they are usually shorter-ranged than most of the other weapons in the game.

Flamer

 * Flamers are short-ranged special weapons carried by various soldiers, Imperial and otherwise, in the Warhammer 40,000 universe. To represent the ease of use of a flamethrower, the game mechanics of this weapon differ from that of other ranged weapons. Instead of rolling dice to hit a target, firing a flamer (and other similar weapons) simply involves placing a teardrop-shaped template over a target. In-game, anything touched by the template is automatically hit, with no reliance on probability.


 * Many units, both Imperial and non-Imperium, are capable of carrying flamers. While Space Marines and Imperial Guardsmen can be armed with them, flamers are iconic weapons of the Sisters of Battle, of the Witch Hunters faction. Unlike other weapons which have analogs in other armies, flamers generally have no specialised versions in the non-Imperial armies that they are found in; They are simply referred to as flamers. Both Eldar and Tau Empire factions have specific units that can be armed with flamers.  Their flamers are identical in game stats and name to the Imperial version, and differ only in appearance. Orks have a specific analog of the flamer, the burna.

Hand flamer

 * Hand flamers are smaller, one-handed versions of the normal flamer. They are often used by assault troops, where the weapon's shorter range is less noticeable. In the first two editions of Warhammer 40,000, the hand flamer used a small teardrop-shaped template similar to that of the standard flamer's. Since the third edition of the game, hand flamers have been almost completely written out of the rules and they are now simply close-combat weapons in game terms. An exception to this is found in the Witch Hunters codex. Sisters of Battle Seraphim can be armed with twin-hand flamers, which in-game fire as a standard flamer.


 * Hand flamers are still relatively common in the underhives within the Imperium.

Heavy flamer

 * Heavy flamers are larger, more powerful versions of the standard flamer. In game terms, this translates into heavy flamers being stronger and having better armor-piercing capabilities than flamers. During the first and second editions of Warhammer 40,000, heavy flamers used a larger, longer-ranged template than flamers. With the release of the third edition, heavy flamers used the same template (and thus had the same range and area of effect) as the standard flamer.


 * Heavy flamers are often used by specialists in dense conditions, such as jungle warfare, urban warfare and close-quarter combat. As an infantry weapon, they are not as common as flamers and fewer units are capable of using them. One of the earliest units to have the weapons were Space Marine Terminators, who made use of them in cramped ship-boarding actions in the game Space Hulk. The Sisters of Battle of the Witch Hunters faction are one of the few infantry units allowed to carry heavy flamers. Some Imperial Guard armies are capable of fielding heavy flamers in squads of infantry, specifically armies that use the Jungle Fighters doctrine special rule such as the Catachan Jungle Fighters. Heavy flamers are also encountered on Imperial armoured vehicles, such as the Sentinels and Chimeras of the Imperial Guard. They are possible secondary weapons for some Space Marine vehicles as well, such as Dreadnoughts and Land Speeder Tornadoes. As of the third edition release of Codex: Witch Hunters, the Sisters of Battle Immolator tank is armed with heavy flamers. Space Orks possess an analog to the heavy flamer with near-identical game stats, the skorcha.

Incinerator

 * The Incinerator is a specialized heavy flamer variant seen primarily in the Daemonhunters army list. It is used mostly by the Grey Knights Chapter. Incinerators are different from heavy flamers in that their promethium fuel is consecrated for use against daemons and other similar warp entities. In-game, the weapon is almost identical to the heavy flamer, except that it completely ignores the invulnerable saving throw special rules, which all daemons have.

Inferno cannon

 * The Inferno cannon is a flame weapon used primarily by the Imperial Guard. It is the primary armament of the Hellhound flame tank.


 * In-game, the Inferno cannon used to have the same range as the flamer during the third edition of Codex: Imperial Guard. The fourth edition of the Imperial Guard codex changed the way the cannon worked fundamentally. Instead of having a short range, its in-game range was extended to three times as far. This was justified by the image of a flame tank shooting a long gout of flame at range over an area versus just spewing fire directly from the cannon. This firing effect can be clearly seen in Hellhounds in the game Dawn of War.


 * Through Forgeworld, the Space Marines gained access to the Inferno Cannon, mounted on customized "Siege Dreadnoughts," which also featured a Dreadnought Close Combat Weapon similar to a Chainfist, with an inbuilt Heavy Flamer. This could be used most effectively against bunkers and transport vehicles, where upon a penetrating hit all occupants of the target would suffer a hit by the Heavy Flamer.

Laser weapons
Laser weaponry or Las weapons are laser-based ranged weapons used by many forces in the Warhammer 40,000 universe. Descriptions and depictions of their effects vary between authors and artists from firing a single coherent ray of light, as seen in the video game Warhammer 40,000: Dawn of War. , to Star Wars-type blasters with recoil, to invisible beams without any apparent recoil or muzzle flash. These weapons are relatively easy to produce and maintain. They require no solid ammunition, and use power cells which can be recharged or quickly swapped with a fully-charged power cell. This makes them ideal for distribution among large numbers of men, such as the Imperial Guard. While the accuracy of a laser is generally depicted as not being distorted by wind unlike projectile weapons, it can be diffused by heavy particles in the air such as smoke and thus a laser can dissipate over long distances. However, authors such as Dan Abnett, depict las weapons as having muzzle flash, noticeable recoil, and aim being affected by gravity, accuracy being affected by wind and able to fire underwater, in effect being the same as projectile weapons.

Defence Laser

 * The Defence Laser is an immense laser weapon and is normally in use only in fixed emplacements or on very large vehicles. The Imperator pattern Titan mounts one as an anti-aircraft cannon. The Defence Laser name was introduced in WH40K: Rogue Trader but in the more recent game editions it seems to have been replaced by the specific Volcano and Nova cannons.

Hellgun

 * A hellgun is an upgraded lasgun which fires a substantially stronger beam, using a series of focusing lenses and a completely revamped power feed to give it a far greater armour-penetration factor compared the typical lasgun. However, the higher power output requires superior quality power cells or a backpack power supply to keep maintained, and the complex gun system requires more time and resources to manufacture and repair - as well as more training to get the most out of. This makes it more costly to field, so it is not generally issued to the average Imperial Guardsman. However, Storm Troopers and Grenadiers are always equipped with a hellgun as standard to take full advantage of their superior training and weapons expertise.

Hellpistol

 * The hellpistol corresponds to the laspistol the same way the hellgun corresponds to the lasgun - it is deadlier and only slightly heavier than the laspistol. However, it is correspondingly more expensive in terms of materials and manpower to manufacture and are usually found with grenadier or storm trooper sergeants, although higher-ranking officers also have access to this weapon by virtue of their higher rank. Some Inquisitors will also use this weapon as a matter of preference.

Lascannon

 * The lascannon is one of the anti-tank weapons available to Imperial forces. Its high strength and armour-piercing ability make it a formidable weapon. The weapon fires like a lasrifle just with a bigger "las" burst.  Space Marines make extensive use of lascannons, and are also fielded in Imperial Guard heavy weapon squads. Lascannons are also mounted on Land Raiders, Predator Annihilators and many other Imperial vehicles.

Lasgun

 * The lasgun is the standard-issue weapon for all Imperial Guardsmen. It fires a focused pinpoint laser bolt, which is effective when used en masse, but considerably less effective when used singly. However, they are powerful enough to remove an unarmoured human limb in a single blast, although these shots are individually not as effective against durable alien bodies or heavy armour.


 * Lasguns are powered by small rechargeable power packs and power setting slides which can be utilised to further decrease power usage. The power packs are extremely reliable and can be recharged by exposing them to direct sunlight or by throwing them in an open flame, although the latter reduces the life time of a power pack and increases the chance of misfires. These in-universe features of the lasgun does not make an impact in the Warhammer 40,000 game, where ammunition is not a factor, but the power pack feature is implemented in the Necromunda tabletop skirmish game. In Necromunda, lasguns can easily pass ammunition rolls which check whether a particular weapon has run out of ammo.


 * Certain types of lasgun have specific uses, such as the more powerful long las which is a term used to refer to modified sniper lasguns, usually because they bear longer barrels and range. These weapons also use overpowered liquid metal batteries known as hotshots, and have only one power setting. This quickly wears out the barrels, which are replaceable and good for about twenty shots each. The lascarbine is a carbine form of the lasgun, designed for special operations and units, usually employed by drop troopers or scout units of the Imperial Guard. It is light and compact, allowing it to be easily stowed away so that it does not interfere with the carrier's mobility. It was used by the Tanith First & Only, Elysian Drop Troops, Catachans and Inquistor Gregor Eisenhorn. A particularly rare form is the Assault Laser, wielded almost entirely by private concerns due to its' high maintanance requirements - the focussing rings must be replaced every thousand shots or so. Assault Lasers are known for their immense rate of fire and slightly higher armour-piercing ability compared to the standard lasrifle.

Laspistol

 * The laspistol is the pistol form of the lasgun, and operates in a similar way. It is suitable for quick use rather than firepower or range, and is often used in conjunction with a close combat weapon. Many laspistols have power packs mounted in front of the pistol's grip rather than within the grip itself, so that heat from the power cell can be quickly dissipated and the power cell quickly changed when depleted. While it is more likely to be hit when exposed and cause a potentially debilitating explosion, the likeliness of this occurring is outweighed by the benefits.


 * Laspistols are carried primarily by Imperial Guard officers and advisers, including Commissars, Techpriest Enginseers and Sanctioned Psykers. Some dedicated close combat units of the Imperial Guard, such as Rough Riders and special weapon squads can also be armed with laspistols.

Multilaser

 * The multilaser is a multiple-barreled laser weapon that fires a torrent of laser beams, similar to a pulse laser. It is described as a lower-powered, multiple-shot version of the vehicle-destroying lascannon.


 * Multilasers have always been used primarily by the armies of the Imperial Guard. They are often mounted on light vehicles that serve either as transports or scouts, for infantry work. Imperial Guard Chimeras and Sentinels are among the few vehicles that are known to mount multilasers.

Turbolaser Destructor

 * The Turbolaser is a large and potent Laser weapon, equivalent to a very large lascannon. In a sense, the Turbolaser is to the Lascannon what the Battle Cannon is to the Autocannon - a larger, more devastating weapon based on the same concept.


 * The weapon is most commonly seen mounted in pairs on Titans - Warhound Scout Titans often carry a pair as one of the arm mounts, while the larger Reaver Battle Titan sometimes mounts a pair of Turbolasers on each arm, and the Warlord Battle Titan generally has a pair in each shoulder mount. However, the weapon is also used elsewhere. Some variants of the Adeptus Astartes Thunderhawk Gunship carry the weapon, instead of a Battle Cannon, when engaged in ship-to-ship combat where a laser weapon is more useful than a battle cannon.

The rare Destroyer Tank Hunter variant of the Leman Russ Battle Tank mounts a similar weapon, used for long range precision 'sniping' against enemy armour. It is worth noting, however, that this weapon is referred to as a laser destroyer, and is completely different to the turbo laser.

Volcano Cannon

 * The Volcano Cannon is the most powerful ground vehicle-mounted laser weapon, and is used exclusively by Titans and the Shadowsword super-heavy tank. It is primarily meant to target huge objects and obliterate them with a single shot. Such targets usually include other Titan-sized opponents and minor hive cities. In earlier editions of Epic, it was referred to as the Deathray, automatically causing critical hits on war engines.

Melta weapons
Melta weapons work by producing a small scale fusion reaction using a pyrum petrol fuel mix. This is projected as a blast of incredible heat. They have a short range but are very powerful weapons and are favoured for use against armoured targets.

Inferno pistol

 * The Inferno pistol is a pistol version but is rare. They are only available to the Ordo Hereticus and the militant arm of the Order, the Sisters of Battle.
 * Commander Dante, of the Blood Angels has an ancient version of this weapon, called the Perdition Pistol, which fires with the same effect as a normal Meltagun, but can still be used in close combat.

Meltagun

 * The meltagun is a commonly found special weapon in the forces of the Imperium. Common imperial slang for meltaguns for them include cookers or vape guns. Meltaguns are a common sight in Space Marine and Imperial Guard armies. They can also be fielded in great quantities by the Sisters of Battle of the Witch Hunters faction.


 * While the technology may not be identical, analogs of this weapon in other Warhammer 40,000 factions include the Eldar fusion gun and the Tau fusion blaster.

Multi-melta

 * The multi-melta (also known as a thermal cannon) is a larger, longer-ranged version of the meltagun. Unlike their smaller cousins, multi-meltas are not commonly carried by infantry. The only foot troops known to carry them include Sisters of Battle, Space Marine Devastators and Servitors. It is more often found mounted on vehicles, such as Space Marine Land Speeders and Sisters of Battle Immolators.

Other melta weapons

 * Meltabomb (see Grenades section)

Plasma weapons
Plasma weapons are a class of high-strength, armor piercing energy weapons in the Warhammer 40,000 universe. They employ a magnetic field to accelerate a ball of ionized gas towards a target. In-universe, plasma weapons are described as being temperamental and the technology to manufacture them has become rather obscure for the Imperium. Despite this, plasma weapons find regular use throughout the armies of the Imperium. Imperial plasma weapons are comparatively stronger than other races' analogs, but this advantage is countered by poor cooling. Plasma weapons using Imperial technology can build up dangerous levels of heat, which is occasionally vented out, seriously wounding the operator. In second edition, Imperial plasma weapons (known as mark II plasma weapons) had added safety mechanisms and did not suffer from this drawback. Instead, they had to recharge between shots. Older type plasma weapons (known as mark I) still had the potential to overheat dangerously. In third and fourth edition game rules, this is represented by the plasma weapon's capability to wound (often lethally) its wielder. The plasma is described as being a "miniature sun", but has appeared as blue, green or light purple in the case of chaos weaponry seen in the video game Dawn of War.

Plasma Annihilator

 * The Plasma Annihilator is the largest known plasma weapon, second only to the capital ship-mounted nova cannon. It is mounted on the Emperor-class Imperator Titan and delivers sufficient firepower to be considered a "Titan killer". Not much is known about these weapons, beyond their awesome destructive capability.

Plasma Blastgun

 * Among the largest versions of Plasma Cannons, these are the main weaponry of Stormblade Super Heavy Tanks. They are also commonly mounted on scout titans such as the Warhound, as one of the most powerful anti-tank weapons they can carry, while battle titans such as the Reaver and Warlord may use them as well.

Plasma Cannon

 * The plasma cannon is a heavy weapon that relies on plasma technology to deliver lethal energy balls. It is much longer-ranged than the plasma gun, and has a wider blast radius.


 * The term plasma cannon was first used to refer to the weapon during the third edition release of the Warhammer 40,000 rules set. Prior to the third edition, the cannons now referred to as plasma cannons were known as heavy plasma guns.


 * As a plasma weapon, the plasma cannon is prone to severely wounding or killing its wielder by overheating. Because of this, only a select few infantry units are known to carry plasma cannons, including Space Marine Devastators and Gun Servitors. Plasma cannons are more commonly seen mounted on vehicles, such as in the side-sponsons of Leman Russ Demolishers.


 * Analogs of this weapon found in other Warhammer 40,000 factions are the kustom mega-blasta of the Orks, the Dark Eldar disintegrator and the Eldar starcannon.

Plasma Destructor

 * The Plasma Destructor is a unique plasma weapon which is mounted in the Leman Russ Executioner. It is the most powerful plasma weapon aside from the ones mounted on Imperial Titans, occupying a middle ground between the Plasma Cannon and the Plasma Blastgun. It is an extremely temperamental weapon that is often criticised by crew for being unable to operate in sustained engagements due to its massive power requirements. However, it has the capability to penetrate most known armour and its extreme destructive potential is the reason that many Imperial Guard commanders try to include at least one Leman Russ Executioner in their armoured formations.

Plasma gun

 * The plasma gun is a rifle-sized plasma weapon common to many of the forces of the Imperium. In-game, is classified as a special weapon and is carried by a variety of Imperial infantry, including Space Marines, Imperial Guardsmen and Stormtroopers. Like other infantry-carried plasma weapons, it retains the in-game capability to wound its wielder.


 * Outside of the tabletop games, the plasma gun can be seen in the computer game Dawn of War, where it can be carried by several Space Marines and Imperial Guard units.


 * Analogs of the weapon can be found in other Warhammer 40,000 factions. Most notable of which is the Tau Empire plasma rifle.

Plasma pistol

 * The plasma pistol is a shorter-ranged, single-handed pistol version of the plasma gun. It is most commonly encountered carried by officers of both Space Marines and Imperial Guard. Aside from characters, some specialized assault troops such as Assault Marines have the capability to be armed with plasma pistols.


 * In the computer game Dawn of War, plasma pistols are carried by upgraded heroes and characters of the Space Marine and chaos factions.

Cyclone missile launcher

 * The cyclone missile launcher is a missile launcher fitted on the shoulders of select Space Marine Terminators. It is connected to targeting systems on the terminator's gauntlet allowing the missiles and the terminator's other weapons to be fired more accurately. In-game, it has the exact same rules as any standard missile launcher, including the ability to fire frag and krak missiles.

Exorcist launcher

 * The Sisters of Battle have a specific missile launcher known as the Exorcist launcher, which is mounted exclusively on the Exorcist tank. Unlike the similar Whirlwind launcher, the Exorcist launcher fires many small missiles.

Havoc launcher

 * Chaos also mounts missile launchers (dubbed the Havoc Launcher) on the hulls of their vehicles. Unlike its imperial equivalent, the Hunter Killer Missile, the Havoc Launcher fires salvos of frag missiles.

Hunter-killer missile

 * Imperial Vehicles can also mount a "Hunter Killer" missile. In essence this is a Krak Missile with unlimited range.

Missile launcher

 * These launchers fire two types of grenade/missile, Frag and Krak. Frag projectiles (short for fragmentation) are designed to spray an area with shrapnel, making them useful against lightly armoured infantry.  Krak projectiles cover less area but they have improved penetrating capabilities, making them useful for either heavily armoured infantry or moderately armoured vehicles.  Missile launchers can also fire missile versions of the Imperium grenade types.

Mortar
The mortar has the ability to bombard enemy positions from behind cover. As such the vulnerability of Guardsmen is reduced and they survive longer. Although with indirect fire abilities the mortar is not exceptionally strong against more powerful troops - and certainly not against tanks.

The rarer Griffon siege mortar has a rather larger explosive force than its man-portable variants, and is an excellent bunker-buster when equipped with specialist siege shells. It is usually mounted on chimera hulls to provide mobile support.

Assault cannon

 * The assault cannon is a six-barreled, self-loading automatic weapon used by a few select vehicles and heavy infantry in the Warhammer 40,000 universe. Effective against massed infantry and light vehicles, the weapon's bulk more-or-less requires it to be mounted on stable platforms such as vehicles.

Compared to other Imperial heavy weapons, there are much fewer units that are capable of carrying assault cannons.

Two common Space Marine vehicles that regularly carry assault cannons are Space Marine Dreadnoughts and Land Speeder Tornados. The Land Raider Crusader's main armaments include twin assault cannons mounted on top of its hull. The Blood Angels Baal Predator, introduced in the third edition release of Codex: Blood Angels, carries a twin assault cannon in its turret. Until the third edition of Warhammer 40,000, Imperial Guard Sentinels were also armed with assault cannons. This was subsequently changed in order to restrict assault cannons solely for Space Marines use.


 * Aside from vehicles, a few infantry types are capable of fielding assault cannons as well. A version of the assault cannon, longer and thinner than vehicle-mounted equivalents, is often fitted onto Space Marine Terminators.


 * Although the assault cannon lacks the range of other rapid-fire guns such as the heavy bolter and the autocannon, its enormous rate of fire enables it to literally shred its way through most targets, punishing them with thousands of rounds per minute. Assault cannons are extremely potent at medium to close range, against armoured infantry and moderately armoured vehicles, while heavy bolters are only effective against lighted armoured targets and auto cannons have a slower firing rate. The assault cannon epitomizes the deadliness of elite Terminator squads who teleport behind the enemy's front line and open up full-automatic fire, spreading carnage and terror. In earlier incarnations of the game the assault cannon was notoriously fickle and prone to jamming, sometimes stopping with enough force to detonate the weapon and kill the user. In the 3rd edition, jamming has been reduced to a slight (1/216) chance and in the 4th edition of the game, the jamming rules have been removed, with additional hitting power known as rending.  This could be due to refinement in the weapon's research, similar to the transition from the combi-bolter to the storm bolter.


 * Assault cannons are used by Planetary Defence Forces on rare occasions as a stand-mounted defensive weapon, and are also found on the Destroyer variant of the Marauder bomber.

Autocannon

 * While autopistols and autoguns are similar to their las-variants, autocannons are unlike their lascannon counterparts. Autocannons are rapid-fire heavy weapons designed to eliminate heavily armoured infantry or light vehicles, and are often used by Imperial Guard heavy weapons teams in battle, due to its versatility and reliability. Autocannons have better penetration than heavy bolters, while greater range than assault cannons, but have a slower rate of fire.

Autogun

 * Autoguns are automatic weapons which fire solid-slug ammunition propelled by one of various methods, including the use of compressed gases. The ammunition used by these weapons are caseless ammunition. Autoguns are still popular among soldiers of the Imperial Guard for reasons such as while having a similar calibre, the bullets are capable of causing bleeding whereas a lasgun's beam cauterises wounds instantly. Also its noise and visual effects are more useful against Orks.


 * It was the standard-issue weapon for the Imperial Guard until the 32nd millennium.

Autopistol

 * An autopistol is a pistol weapon that operates on the same principles as the autogun. It shoots the same caseless projectiles used by autoguns in shorter bursts.

Exitus pistol

 * Used only by the Vindicare Assassin, this is the Assassin's back-up weapon when retreating after assassinating their target with their Exitus rifle. It is a high strength, solid slug weapon.

Heavy stubber

 * A heavy stubber is a slug firing weapon based upon an old design (aesthetically resembling an M2HB machine gun), and is fairly common and reliable. Its high rate of fire makes up for its lack of strength and armour-piercing abilities.  It is an ideal support weapon for low-tech worlds that cannot look after laser weapons through technological or resource limitations.


 * Heavy stubbers are often pintle mounted and used as close defence weapons on Imperial vehicles, when the rarer storm bolters are not available. The Heavy Stubber has relatively poor armor-penetration factor, as it simply fires large-caliber bullets, but it has overwhelmingly better range than the Storm Bolter, so it does continue to see use in even well-equipped armies.


 * The Lost and the Damned often steal these from planetary defenses making these weapons a common sight in their shambling ranks.

Reaper Autocannon

 * A twin-linked version of the autocannon with a shorter range, reaper autocannons were used by Space Marine Terminators prior to the Horus Heresy. They were eventually replaced by the assault cannon, and are now only used by Chaos Terminators, or are mounted on Chaos Defilers.

Ripper gun

 * Ogryns are equipped with the Ripper gun which is a shotgun built to their scale. It is a short range weapon firing several shells at once which helps combat the poor aim of the average Ogryn. They are fired to soften up the enemy before the Ogryns charge into close combat. Ripper guns are particularly robustly built so that they can be used as clubs. These guns can also have "Ripper Saws." These are one of the only weapons an Ogryn can use, due to the Ogryns' immense size and stupidity.

Shotgun

 * An old weapon, much the same as the heavy stubber, which fires solid slugs that burst into submunitions to spread out over a wider area. Most Guardsmen that use the shotgun prefer the double-barrelled version, and its reliability makes it the mainstay of the Elysian Drop Troopers, who prefer it over the lasgun when entering hostile drop zones. The Adeptus Arbites also use the shotgun for crowd control and urban conditions and have developed special 'Executioner' shells for them.


 * Shotguns are commonly used by criminal lowlifes in the lawless regions of most hive cities, where a large variety of specialist ammunition is used, including man-stopper rounds, modified bolt rounds and incendiary shells.


 * Imperial Navy ships carry shotguns for the crew to use during rare boarding actions or, more frequently, against uprisings by crewmen aboard the ship. Space Marine Scout squads are also known to use shotguns in their missions.

Sniper rifles

 * Sniper rifles are specifically made or modified weaponry for use by sniper units in Warhammer 40,000.


 * There are sniper rifles which use solid slug ammunition - although, like other projectile-based weapons, they are restricted by heavier ammunition. The advantage the slug-thrower has over its light based opponent is that fewer enemies will recognize the report of the rifle, as opposed to a long-las' ruby beam.

Exitus rifle

 * Used only by the Vindicare Assassin, this is an improved version of the Sniper rifle. It can also fire special rounds designed specifically for the Assassin.
 * Shield-breaker - ignores field saves.
 * Turbo-Penetrator - causes more wounds on the target, and is also effective against vehicles.
 * Hellfire - wounds easier.

Needler

 * The needlegun and needle pistol (or needler in general) are silent and deadly weapons that uses both laser power and poisoned needles. The weapon fires a laser bolt like the lasgun, which, a millisecond later, is followed by a needle. The bolt melts and cuts through armour, leaving the flesh (or other vulnerable parts) vulnerable to the needle, which knocks out or kills the target.  It is a valuable weapon which needs specialized ammo and care - even more so than the sniper lasgun - and is therefore usually reserved for more elite troops or outfits. The needle is usually formed of a mix of magnetised iron and one or more nerve toxins, engineered to be solid at room temperature, but melt at body temperature. Due to their nature as magnetic induction weapons (see coilgun), Needlers are silent - inexperienced wielders often may not realise that they've actually fired the weapon, due to the complete lack of recoil or sound.

Grenade Launcher

 * These launchers fire two types of grenade, frag and krak. Grenades, naturally, are less powerful than missiles, but are easier to fire on the move. They can also fire more exotic types of grenades, as below, though these are not standard issue, and need to be loaded for firing individually.

Grenade types

 * See the Grenade section.

Animus Speculum

 * Used exclusively by the Culexus Assassin temple, this is a warp-based weapon that fires warp blasts from the Assassins' Etherium mask. This weapon has a higher rate of fire if there are beings with psychic powers near the assassin.

Conversion beamer

 * The Conversion beamer is a heavy weapon that fires a burst of energy that turns the material of the target into more energy. As such it is equally effective against large targets as small ones. On the other hand the beam has to be held very steady to achieve the effect so the weapon cannot be used on the move.
 * The beamer was dropped from the WH40K games at the publishing of the 3rd edition of the rules.

Neural Shredder

 * An alien device used mainly by the Callidus Assassin temple. Anyone caught in the weapons blast is affected mentally, meaning that troops with lower mental capacity are more likely to be affected.

Web weapons

 * Web weapons, or "glue guns" fire a "net" of sticky material and as such is intended to immobilize rather than kill targets, though if the target continually struggled, the web would tighten to the point of killing the target. Some webbers fire an anesthetic-laden web, rendering the target unconscious.  Its main use is in crowd control and mob suppression, and is rarely seen on the battlefield.
 * It was introduced in WH40K Rogue Trader and featured in the 2nd edition wargear book, but later dropped from the background when the 2nd edition Codexs were released.

Heavy webber

 * The largest version of the web gun, it had the added ability of being able to jam the wheels/tracks and doors of vehicles, rendering them temporarily immobile. It also had a larger effect radius, meaning it could entangle more opponents.

Web pistol

 * The smallest size webber, it could be used in one hand, and as such could be used to immobilise an opponent in close combat.

Webber

 * The standard "rifle" form, with a longer ranger than the pistol, and a greater area of effect.

Anti-plant grenade

 * A small hand-held device which kills all plant life within its blast radius, thereby removing an enemies' cover.


 * In the game Warhammer 40,000: Chaos Gate, anti-plant grenades can be used by the player to defoliate forested areas in the game.

Blind grenade

 * A more sophisticated type of smoke grenade, that emits infra-red bafflers and broad-band spectrum electro-magnetic radiation in addition to smoke, to blind not only normal eyesight but also artificial sight aids. In-game, blind grenades were not initially present in the third edition of Warhammer 40,000. Blind grenades were reintroduced into the game with a rules addendum in a subsequent issue of White Dwarf Magazine.

Choke grenade

 * Explodes to fill its blast radius with a non-lethal gas which prevents anyone in the from breathing properly, temporarily incapacitating them.

Frag grenade

 * A small hand-held explosive device meant to hurl shrapnel in all directions.


 * In different Warhammer 40,000 novels the space marine variety is described in one of two ways, either disc shaped with a button in the center that can be pressed repeatedly in order to determine how long until it explodes, or a small egg shape. Both kinds of space marine grenade designs are described as "micro-grenades" and are apparently smaller.


 * Frag grenades are common weapons in the Warhammer 40,000 computer game Chaos Gate.

Hallucinogen grenade

 * Fills its area of effect with an invisible hallucinogenic gas, causing anyone breathing it in to experience visions which may have various effects on them, from nothing to running from the field screaming.

Haywire grenade

 * Haywire grenades (or scramblers) are grenades that explode with a powerful EMP effect, destroying electronic systems and incapacitating vehicles. In the background, they are described as having crystal batteries.

Krak grenade

 * Grenades meant to be used against hardened targets such as armoured vehicles or buildings, etc.


 * Krak grenades are common weapons in the computer game Warhammer 40,000: Chaos Gate.

Meltabomb

 * The meltabomb is a grenade version of the melta gun technology.

Photon Flash flare

 * Explodes with a tremendously powerful flash of light, which will temporarily blind anyone without protection in its area, and may even effect those with protection, such as power-armoured Space Marines.

Plasma grenade

 * Rare in the Imperium, these explode to produce a ball of plasma that covers an area. This will shrink as it uses the available energy in the surrounding area.
 * The Eldar use a different kind of plasma grenade.

Psyk-Out grenade

 * The rarest grenade in the Imperium, it is produced from a psychic by-product collected from the Emperor's Golden Throne. Used exclusively by the Culexus Assassin temple, it is only useful against beings with psychic powers, but can kill such a being instantly.

Scare grenade

 * Produces a non-persistent gas, absorbed through the skin, with affects the nervous system of those affected, producing feelings of apprehension and deep anxiety.

Rad grenade

 * A small hand-held explosive device which irradiates the area encompassed in the blast area. The radiation level dissipates over time.

Smoke grenade

 * A simple grenade that fills the area with thick smoke. Effective against normal eyesight, Smoke is useless against more sophisticated visual devices. The release of Warhammer 40,000 3rd edition removed the rules for most grenades in-game. Smoke grenades were reintroduced into the game with a rules addendum in a subsequent issue of White Dwarf Magazine.

Stasis grenade

 * The Stasis grenade is a very rare type of grenade used only by the forces of the Adeptus Mechanicus and a few other select Imperial special forces. In-game, the stasis grenade "traps" any units in its area of effect, rendering them incapable of doing anything. This is described in the background as the grenade having a "time-warp generator" that essentially generates a time-loop, causing time to repeat itself within the grenade's area of effect. This grenade has not appeared in game rules since the third edition of Warhammer 40,000.

Tanglefoot

 * Another rare grenade device, produced in small numbers by the Adeptus Mechanicus, and issued to elite Imperial forces. It contains a small but powerful magno-gravitic generator, which produces a field at, and just above, ground level, making it difficult to move through.  It is said to be like "walking over a mass of tripwires", hence its name.

Toxin grenade

 * The Toxin grenade spews an amount of toxic chemicals and biological extracts over an area.

Virus grenade

 * A grenade designed for germ warfare. Though relatively safe, there is an inherent risk of mutation within the toxins, meaning it is rarely used except in cases of strategic destruction. Because of its random nature, this device can be as dangerous to its user as their opponent.

Vortex grenade

 * A rare hand-held device which opens a "hole" to the Warp, destroying any troops in is area of effect. Under older editions rules, the effect was persistent, and the vortex would randomly move across the battlefield.


 * The vortex grenade is a rare, but usable weapon in the computer game Chaos Gate.

Battle Cannon
Battle Cannons, the standard weapon for the Leman Russ Battle Tank, are formidable and can deal significant damage from a long distance. The cannon devastates an area and may be fired from behind cover. The sheer power of this weapon makes it a good choice for most armies.

Mega Battle Cannon

 * The Mega Battle Cannon is a larger version of the Battle Cannon and fires rocket propelled ammunition. It is the main armament of the Baneblade tank.

Vanquisher Cannon

 * A more complex variant of the Battle Cannon, the technology to create Vanquisher Cannons is held by only a few Forge Worlds. Its most obvious feature is that it is almost twice as long as the standard battlecannon. It uses specialised armour piercing shells to take down enemy tanks from afar. Vanquisher Cannon-armed Leman Russes are often used as command tanks, where the veteran crew's experience can make the best use of the weapon.

Conqueror Cannon

 * The Conqueror Cannon is a lightweight alternative to the Battle Cannon used on Leman Russ tanks. Although the cannon has a shorter range and fires smaller shells, the drastic reduction in recoil allows the vehicle to fire with more accuracy on the move. The only Forge World producing them in large numbers was Gryphonne IV.

Demolisher Cannon
Mounted on the Imperial Guard Leman Russ Demolisher and Space Marine Vindicator, the Demolisher Cannon is a weapon designed to get up close and personal before it is fired. It is among the strongest weapons fielded by the Imperial Guard at regiment level, the sheer damage it is capable of doing is enough reason to risk getting so close, as well as the improved armour on the tank to increase its survivability. It is most often used in a bunker-buster role, by driving up close to enemy fortifications and firing into them at very short range, and allowing allied forces to assault through the breach. They are also used in urban areas, where they are aimed at the base of an enemy held building and fired, causing the building to collapse.

Earthshaker Cannon

 * The Earthshaker cannon or 'Earthshaker' artillery gun is a large artillery weapon used by the Imperial Guard. It has the one of longest ranges of any weapon in the entire game, with an in-game range of ten feet. In various cases, the cannon can be upgraded to be able to fire indirectly in the same way as traditional artillery pieces like howitzers. When upgraded this way, the weapon's in-game range is doubled to twenty feet, much longer than the tables the game is prescribed to be played on.


 * The weapon itself can be found mounted on the Imperial Guard's standard artillery piece, the Basilisk. The Earthshaker can also be fielded as static artillery pieces using supplementary rules provided by Forge World in the Imperial Armour sourcebooks.


 * In the background, the Earthshaker is described as a very long ranged weapon, capable of bombarding the rear of the enemy camp without having to be anywhere near it. Its shells are packed with powerful explosives that will destroy nearly anything within a sizable radius. While it is not as strong as the Demolisher Cannon in terms of brute explosive force, its remains an invaluable weapon thanks to its range, and the ability to use indirect fire.


 * Before being named as the Earthshaker cannon, the gun on the Basilisk self propelled gun was reported as the "Macro-cannon".

Deathstrike Cannon
A very large long ranged cannon weapon that was available on early-style Warlord Titans. It replaced the head potentially giving the Titan five weapon mounts, except that then a carapace mount position had to be given over to a fire control tower. (Citadel Catalogue 1991)

Inferno Gun
A massive flamethrower weapon used mostly on Warhound Scout Titans and Hellhound Fast Attack Tanks.

Whirlwind launcher

 * The Whirlwind multiple missile launcher is a turret-mounted missile launchers used by the Space Marine Whirlwind. The launcher is capable of firing missiles that, in-game are effective against both infantry and light vehicles. A new function of the weapon introduced with the fourth edition of the Codex: Space Marines allows it to fire Castellan missiles, which are modified to deploy minefields on the battlefield. The original missiles that the Whirlwind used to fire are still available and have been dubbed Vengeance missiles. In the fourth edition release of Codex: Dark Angels, the standard Castellan missiles were replaced with Incendiary Castellan Missiles. These differ from the former by losing the minefield aspect of the weapon. Instead, the incendiary version has lowered strength and armour-piercing capability but has the in-game effect of ignoring the rules for cover to represent an incendiary firestorm engulfing an entire area in flames.


 * Another vehicle that carries the Whirlwind launcher is the Land Raider Helios.

Mole Mortar
The Mole Mortar fires a shell that travels underground to its target rather than through the air. It is useful for attacking burrowing vehicles and the foundations of buildings.

Thudd gun
The Thudd gun is a quadruple barreled short range artillery weapon on a mobile mounting. Also, as it was once out of production but Forge World has recently released a new version with experimental rules for use in games of warhammer 40k.

Tarantula
The Tarantula is not an individual weapon but a weapon mounting that can be moved readily about the battlefield. It is able to mount two heavy weapons.

Rapier
The Rapier is again a weapon mount rather than a weapon. It is a small tracked mount that can carry a multi-laser - the multilaser being too large to be carried by a trooper in the same manner as the lascannon.

Ship-based missile systems
Massive versions of the hand-sized grenades, these can be launched from a vessel in orbit, either to provide fire support for troops on the ground, or to destroy an enemy from space.

Note on Chaos Marines
It should also be noted that much of the weapons and equipment used by the Chaos Space Marine Legions also come from this list—especially the equipment wielded by Space Marines. Since the Horus Heresy, the Imperium has made some advances in technology; thus much of the Chaos Marines' equipment is of older design, or the Chaos Marines simply have restricted or no access to some of the items listed above.

For example, the Chaos Marines possess plasma weapons - however, their plasma cannons, being much older, are simply too large to be carried by a man; thus they are always vehicle-mounted. Rather than Stormbolters, which were designed around the time of the Heresy, the Chaos Marines possess older combi-bolters—which are essentially two normal bolters combined into a single gun, but the effect is not quite as effective as the Stormbolter. This has, however, given Chaos pintle-mounted combi-bolters a special utility unknown to Imperial vehicles: the weapon can be adapted to consist of a single bolter combined with a single-shot flamer or meltagun.

Further still, the Chaos Marines have extremely limited access to jump packs (which were designed shortly prior to the Heresy), and no access to assault cannons, psycannons or the special ammunition types for bolters (except inferno bolts), as all of these were invented after the Heresy.

However, some equipment is replaced by similar daemonic gear. For example, some Chaos Marines can be seen with mutated wings, which act similar to jump packs. While Chaos Marines do not have Artificer Armour (a type of power armour which is well crafted so that it affords better protection), they can have their armour mutated by the powers of Chaos, creating Daemon Armour, which is similar to Artificer Armour. Lastly, the Iron Warriors Legion is known for salvaging Imperial siege equipment, such as the Imperial Guard Basilisk (an artillery piece which carries the Earthshaker cannon) and the Space Marine Vindicator.
