03. Armor, Power Armor, Bionics, Vehicles, and Voidcraft

Protection in the Imperium

Imperial armor is designed for many different users and environments.

A hive enforcer, Guardsman, voidship armsman, noble officer, Sister of Battle, and Space Marine may all wear protective equipment, but their armor differs greatly in weight, cost, purpose, and availability.

Armor may protect against:

• Projectiles

• Energy weapons

• Fragmentation

• Heat

• Radiation

• Vacuum

• Chemical exposure

• Hostile environments

• Close-combat attacks

Exact Armor Class and properties belong in Item entries.

Flak Armor

Flak armor is one of the Imperium’s most common forms of military protection.

It is usually made from layered impact-resistant materials designed to reduce injury from fragments, blasts, and ordinary weapons.

Common forms include:

• Flak vests

• Flak jackets

• Guard uniforms with armored panels

• Scout armor

• Reinforced work clothing

• Voidship security armor

Flak armor is affordable, relatively light, and easy to issue in large numbers.

It does not make its wearer invulnerable.

Carapace Armor

Carapace armor uses rigid plates to provide stronger protection.

It is often worn by:

• Elite soldiers

• Storm troops

• Arbites

• Officers

• Inquisitorial agents

• Enforcers

• Mercenary specialists

• Vehicle crews

Carapace armor is heavier and less flexible than ordinary flak but better suited to direct combat.

Full suits may include helmets, environmental seals, communication systems, and integrated equipment.

Protective Fields

Some Imperial equipment generates an energy field that deflects or absorbs attacks.

Examples may include:

• Refractor fields

• Conversion fields

• Rosarius devices

• Iron halos

• Vehicle shields

• Void shields

Protective fields are rare and usually associated with rank, wealth, religious office, or ancient technology.

They may be unreliable under sustained attack or require specialized power systems.

Power Armor

Power armor combines heavy protection with powered systems that support the wearer’s movement.

A suit may include:

• Reinforced plating

• Artificial muscles

• Environmental sealing

• Life support

• Auto-senses

• Communications

• Medical monitoring

• Weapon interfaces

• Internal power systems

Power armor is difficult to manufacture and maintain.

Most human users require training, fitting, and specialized support.

Human Power Armor

Human-sized power armor may be worn by:

• Adepta Sororitas

• Inquisitors

• High-ranking officials

• Mechanicus agents

• Elite warriors

• Wealthy nobles

Such armor is powerful but less integrated than Astartes battleplate.

A human user does not gain the full physical advantages of a Space Marine’s implants and transhuman body.

Astartes Power Armor

Space Marine armor is designed around the altered physiology of the Adeptus Astartes.

It connects directly to the wearer through specialized implants, allowing the suit to move as an extension of the body.

Astartes armor provides:

• Heavy protection

• Environmental survival

• Enhanced strength

• Advanced targeting

• Battlefield communication

• Medical support

• Sensor systems

Each suit may contain ancient components, Chapter markings, honors, repairs, and relics from earlier wearers.

Common Astartes Patterns

Different armor configurations serve different battlefield roles.

Examples include:

• Tacticus: General-purpose battleplate

• Phobos: Lighter armor for infiltration, scouting, and stealth

• Gravis: Heavier armor for durability and heavy weapons

• Terminator Armor: Extremely rare tactical dreadnought armor for the most dangerous assaults

Exact benefits belong in dedicated Armor entries.

These patterns should feel distinct without making one universally superior.

Armor Condition

Armor may be:

• Newly issued

• Well maintained

• Battle-worn

• Damaged

• Improvised

• Master-crafted

• Poorly fitted

• Corrupted

• Missing seals

• Repaired with mismatched parts

Battle damage may affect appearance, reputation, environmental protection, or specific mission conditions without always changing Armor Class.

Bionics and Augmetics

The Imperium commonly replaces damaged flesh with mechanical parts.

Augmetics may replace or enhance:

• Arms

• Legs

• Eyes

• Ears

• Lungs

• Hearts

• Spines

• Hands

• Skin

• Internal organs

For many citizens, bionics are medical necessities rather than luxury enhancements.

Quality of Augmetics

Bionics vary greatly in quality.

A crude industrial replacement may be heavy, painful, and difficult to maintain.

A military-grade limb may be reliable and durable.

A rare master-crafted augmentation may exceed natural human capability.

Quality may depend upon:

• Wealth

• Rank

• Faction

• Local technology

• Medical urgency

• Available parts

• Mechanicus favor

Two characters with bionic arms may have completely different experiences.

Social Meaning

Augmetics can communicate identity and status.

Among the Mechanicus, extensive augmentation may represent spiritual advancement.

Among soldiers, bionics may mark survival and sacrifice.

Elsewhere, visible mechanical replacement may inspire respect, fear, pity, or suspicion.

Not every augmetic should be treated as unusual in a setting of constant industrial injury and war.

Vehicles

Imperial vehicles range from civilian transports and mining machines to tanks, walkers, aircraft, and siege engines.

Common categories include:

• Ground cars and trucks

• Armored personnel carriers

• Tanks

• Scout vehicles

• Walkers

• Artillery

• Aircraft

• Cargo haulers

• Industrial machines

• Bikes and cavalry substitutes

Vehicles provide speed, protection, firepower, and cargo capacity.

They also require fuel, crews, maintenance, and suitable terrain.

Vehicle Crews

A military vehicle may require:

• Driver

• Commander

• Gunner

• Loader

• Vox operator

• Enginseer

• Additional passengers

Player characters may fill several roles or operate simplified vehicles designed for smaller crews.

Large vehicles should still feel like machines supported by teams rather than oversized personal equipment.

Walkers and Dreadnoughts

Walkers use mechanical legs to cross terrain unsuitable for ordinary vehicles.

They may include:

• Scout walkers

• Combat walkers

• Industrial loaders

• Knight suits

• Sentinels

• Dreadnoughts

A Dreadnought is not merely a vehicle. It is a life-support sarcophagus carrying a severely wounded Space Marine within an armored war machine.

Exact statistics belong in Monster or Vehicle entries.

Aircraft

Imperial aircraft may serve as:

• Transports

• Gunships

• Fighters

• Bombers

• Reconnaissance craft

• Atmospheric landers

Aircraft can dramatically change an adventure’s scale.

Their use depends upon landing zones, fuel, air defenses, pilots, weather, and mission authority.

Voidcraft

Voidcraft range from small shuttles to vessels several kilometers long.

Common types include:

• Shuttles

• System patrol craft

• Freighters

• Escorts

• Cruisers

• Battleships

• Rogue Trader vessels

• Mechanicus Explorator ships

• Space Marine strike cruisers

• Inquisitorial vessels

Most large voidships are ancient communities as well as machines.

Thousands of crew may live and die aboard them without ever seeing a planet.

Voidship Systems

A major voidship may contain:

• Plasma drives

• Warp engines

• Gellar fields

• Life-support systems

• Weapons batteries

• Launch bays

• Astropathic chambers

• Navigator sanctums

• Cargo holds

• Machine shrines

• Crew districts

• Defensive armsmen

Damage to one system may threaten the entire vessel.

Voidship adventures can therefore involve exploration, repair, politics, and survival as well as combat.

Warp Travel

Voidships require specialized systems and personnel to travel through the Warp.

Important requirements include:

• A Warp-capable engine

• A functioning Gellar field

• A Navigator or other approved method

• Reliable charts

• Astropathic support

• Adequate supplies

• A stable route

Warp travel remains dangerous even aboard a well-maintained vessel.

Detailed travel rules belong in World Rules.

Maintenance and Supply

Armor, bionics, vehicles, and voidcraft depend upon support.

They may require:

• Fuel

• Power

• Ammunition

• Replacement parts

• Sacred oils

• Technical crews

• Medical care

• Calibration

• Docking facilities

• Forge access

A rare suit of armor or vehicle can become difficult to use far from its support network.

Franz should use maintenance to create occasional challenges rather than constant punishment.

Ownership and Authority

Heavy armor, military vehicles, and voidships are rarely ordinary private property.

They may belong to:

• The military

• A noble house

• A Rogue Trader dynasty

• The Mechanicus

• A Space Marine Chapter

• The Inquisition

• A guild

• A planetary government

• A mercenary company

Characters may operate powerful equipment without legally owning it.

Theft, loss, or unauthorized use can create political consequences.

D&D 5e Mechanical Use

Exact statistics belong in Item, Vehicle, Monster, and World Rule entries.

This lore can support:

• Armor proficiency

• Tool checks

• Vehicle proficiency

• Repair

• Requisition

• Environmental protection

• Crew roles

• Chase scenes

• Boarding actions

• Salvage

• Travel complications

Powerful equipment should create new options while preserving risks, responsibilities, and logistical limits.

Armor and Vehicles in Play

This lore can support adventures involving:

• Recovering stolen power armor

• Repairing a damaged vehicle

• Protecting an Enginseer

• Replacing a failed bionic

• Escorting an armored convoy

• Capturing an enemy transport

• Surviving a voidship breakdown

• Restoring a Gellar field

• Recovering a Dreadnought

• Escaping a blockaded system

Imperial protection and mobility are never only questions of strength.

They also depend upon crews, authority, maintenance, and the ability to keep ancient machines alive.
