02. Imperial Weapons

Weapons of a Vast Imperium

Imperial weapons range from simple blades and improvised firearms to plasma guns, meltas, and power weapons.

The same weapon may appear in many local patterns. Quality, condition, ammunition, legality, and maintenance often matter as much as raw power.

Las Weapons

Las weapons are among the Imperium’s most common military arms.

They are reliable, relatively light, easy to train with, and use rechargeable power packs.

Common forms include:

• Laspistols

• Lasguns

• Carbines

• Long-las rifles

• Hot-shot weapons

• Multi-lasers

• Lascannons

They are effective against ordinary infantry but less reliable against heavy armor and powerful creatures.

Long-Las and Hot-Shot Weapons

Long-las rifles emphasize accuracy and range. They are used by scouts, snipers, Ratlings, and reconnaissance troops.

Hot-shot las weapons use higher-output power systems for greater penetration, usually at the cost of heavier equipment and increased maintenance.

Exact rules belong in Item entries.

Bolt Weapons

Bolt weapons fire self-propelled explosive rounds that penetrate and detonate.

They are powerful, intimidating, and commonly associated with:

• Space Marines

• Adepta Sororitas

• Inquisitors

• Commissars

• Officers

• Elite agents

Astartes-pattern weapons are larger and built for transhuman users, while human patterns are more manageable.

Specialized bolt ammunition may provide armor-piercing, incendiary, fragmentation, toxin, silenced, guided, psychic, or anti-xenos effects.

Plasma Weapons

Plasma weapons discharge intensely energized matter capable of damaging heavy infantry, vehicles, monsters, and fortifications.

Examples include plasma pistols, plasma guns, calivers, incinerators, and cannons.

They are powerful but may overheat, require rare parts, and injure careless users.

Their danger should remain meaningful without making every shot likely to fail.

Melta Weapons

Melta weapons produce extreme short-range heat that destroys armor, machinery, and fortifications.

Common forms include:

• Inferno pistols

• Meltaguns

• Multi-meltas

• Thermal cutters

• Breaching weapons

They excel against vehicles and hardened targets but require the wielder to approach closely.

Solid-Projectile Weapons

Autoguns, stub weapons, revolvers, shotguns, rifles, and heavy stubbers remain common throughout the Imperium.

They are easy to manufacture and modify but require a steady supply of physical ammunition.

They are widely used by:

• Civilians

• Gangs

• Militias

• Ship crews

• Frontier settlers

• Enforcers

• Mercenaries

Shotguns are especially useful in tunnels, underhives, boarding actions, and close-quarters fighting.

Flame, Chemical, and Explosive Weapons

Flamers project burning fuel and are used for suppression, purification, tunnel clearing, and area denial.

Chemical weapons may include toxins, gas, sedatives, and anti-organism compounds. Their use is often restricted.

Explosives may include:

• Fragmentation grenades

• Krak grenades

• Smoke grenades

• Stun grenades

• Melta bombs

• Breaching charges

• Demolition charges

These weapons can solve tactical problems but are dangerous in enclosed spaces.

Power Weapons

Power weapons surround a striking surface with an energy field that disrupts matter.

Common forms include swords, axes, mauls, fists, spears, claws, knives, and crozius weapons.

They are highly effective against armor and are often symbols of rank, office, faith, or honor.

Losing one may carry political or personal consequences.

Chain and Force Weapons

Chain weapons use moving toothed blades to tear through armor and flesh. They are loud, brutal, and psychologically intimidating.

Force weapons channel psychic power and are used by psykers, Librarians, Inquisitors, and other specialists.

Exact abilities belong in Item, Class, or Spell entries.

Primitive and Improvised Weapons

Knives, swords, spears, bows, axes, clubs, hammers, and shields remain common on many worlds.

Improvised weapons may be made from industrial tools, scrap, mining equipment, broken machinery, or fuel containers.

They are often situational, awkward, and dangerous, but useful when conventional weapons are unavailable.

Heavy Weapons

Heavy weapons are used against groups, vehicles, monsters, and fortifications.

Examples include:

• Heavy bolters

• Autocannons

• Lascannons

• Missile launchers

• Mortars

• Plasma cannons

• Multi-meltas

• Heavy flamers

• Heavy stubbers

They often require bracing, ammunition bearers, power units, or support crews.

Mounted weapons aboard vehicles, fortresses, and voidships belong in dedicated Item, Vehicle, or Area entries.

Condition and Maintenance

Weapons may be new, worn, damaged, improvised, master-crafted, corrupted, poorly copied, or missing parts.

Maintenance may require:

• Cleaning

• Calibration

• Lubrication

• Cooling

• Spare parts

• Ammunition inspection

• Power-cell replacement

• Machine rites

• Technical tools

Maintenance should matter after damage or harsh missions without becoming constant bookkeeping.

Ammunition and Supply

A powerful weapon remains useful only while its ammunition, power, fuel, or replacement parts remain available.

Important supplies include:

• Power packs

• Bolts

• Shells

• Plasma fuel

• Promethium

• Missiles

• Grenades

• Specialized ammunition

• Coolant

• Replacement barrels

Scarcity should create decisions, not repeatedly prevent characters from using their defining equipment.

Ownership and Legality

Local law may restrict military weapons, explosives, plasma arms, heavy weapons, power weapons, xenos equipment, and corrupted gear.

Legal access may require:

• Military rank

• Faction membership

• A warrant

• A patron

• Requisition authority

• Black-market contacts

An unusual weapon can reveal status, faction allegiance, criminal activity, battlefield salvage, or xenos contact.

D&D 5e Mechanical Use

Exact damage, range, properties, weight, cost, ammunition, and special rules belong in Item entries.

Broad weapon identities should remain distinct:

• Las weapons offer reliability

• Bolt weapons deliver explosive force

• Plasma weapons provide dangerous power

• Meltas destroy armor at close range

• Power weapons dominate armored melee

Imperial Weapons in Play

This lore can support adventures involving:

• Recovering stolen weapons

• Finding rare ammunition

• Repairing damaged plasma arms

• Tracing a forge mark

• Smuggling restricted equipment

• Recovering an officer’s power weapon

• Sabotaging a heavy emplacement

• Identifying counterfeit ammunition

• Choosing mission-specific loadouts

Imperial weapons are never only tools.

They also represent authority, supply, tradition, and the conditions of endless war.
