Adeptus Astartes Icon

Icon of the Adeptus Astartes

The Space Marines of the Adeptus Astartes maintain a great many awards and decorations for the valour displayed by their transhuman warriors.

Some of these honours exist across all of the Chapters of the Adeptus Astartes, while others are found only within individual Chapters.

Honour badges are used by Space Marines to recognise battle prowess and to designate specialists, such as Apothecaries and Techmarines. Each honour badge has its own customs of display, but are typically worn, painted or embossed on the recipient's power armour.

Some honours, such as the Iron Halo and Imperial Laurel, are commonly displayed on Space Marine standards, particularly Chapter banners.

This page presents some of the most notable honours, decorations and campaign badges available to the Space Marines.

Honours and Badges[]

Purity Seal[]

Purity Seals variants

Purity Seal variants

The Purity Seal is not so much an honour as a blessing given by the Chapter's Chaplains.

Before a campaign the Chaplains pass through the ranks chanting litanies and invocations.

Honoured individuals are marked by the Chaplains for special blessings recorded on the parchment streamers and affixed to their armour with the great wax seal which are often replaced with a more permanent electrum casting of the seal after the battle.

Marksman's Honour[]

Marksman's Honours variants

Marksman's Honours

This device is the Marksman's Honour. Acts of remarkably accurate shooting or consistent performance with targetting of Astartes weapons are honoured with this award.

The Codex Astartes insists that those warriors who prove their accuracy in combat should be singled out so that their skill may be instantly commanded when necessary.

The badges themselves are believed to have been constructed by taking gold Bolter cases, fired in battle from the Boltgun of Roboute Guilliman himself, and encasing them in the award.

Imperial Laurel[]

Imperial Laurels variants

Imperial Laurels - Type 1, 2 & 3

Deeds of valour leading to a great victory for the Imperium are rewarded with the Imperial Laurel. A Battle-Brother who bears this honour has literally earned his laurels.

The wreath is often worn as a crown or sculpted into the Ceramite of an Astartes's helmet. The Wreathed Skull is also a common form of the same honour.

The Codex Astartes demands that company and Chapter standards be borne into battle only by Astartes who have been awarded the Imperial Laurel.

Iron Halo[]

Iron Halos variants

Iron Halo - Types 1 & 2

The simple badge called the Iron Halo has its origins in the earliest days of the Imperium. Often painted onto an Astartes' armour as a red badge, the Iron Halo is the award granted for an exceptional battlefield leader and strategist.

This award is given to those Battle-Brothers who demonstrate exceptional initiative. It is displayed on the shoulder armour or behind the helmet of the Astartes who has earned it as a mark of rank.

Iron Skull[]

Iron Skulls variants

Iron Skulls - Types 1, 2 & 3

A traditional honour badge of ancient origin, the Iron Skull is awarded for the display of exceptional leadership in combat.

It is the Codex Astartes-required insignia for a Space Marine Sergeant and is often displayed on the shoulder armour or helmet of an Astartes of this rank.

The classical convention is to represent the Iron Skull as a red heraldic device.



The Imperialis

The Imperialis was originally the campaign badge used by the Loyalist Space Marine Legions during the Horus Heresy. Over time it has evolved into the "honour of righteous victory" and is awarded to any Space Marine who has participated in an honoured victory for his Chapter.

Instead of being presented as a medal or badge, it is most commonly carved into the deserving Space Marine's chest plate, replacing the armour's standard Imperial Aquila symbol (if the Astartes is wearing Mark VI, Mark VII, VIII or X Power Armour).

It can also be seen engraved on the weapons of Astartes who have earned the badge, and also on banners or atop their heraldry finnials.

It is intended to represent both the Imperium of Man as a whole with the wings of the Aquila and the Emperor's sacrifice for humanity at the end of the Horus Heresy, which is embodied by the skull icon.

Skull and Motto[]

Skull & Mottos variants

Skull & Motto (with a pair of Ultramarines variants)

In addition to the specific badge of the Iron Skull, there are many other icons and emblems which incorporate the skull, a common Imperil motif intended to represent the sacrifice made by the Emperor for humanity's sake during the Horus Heresy.

As honours these decorations often have a multitude of uses and meanings. Often combined with simple mottoes, the skull honour can be seen on shoulder plates, helmets, knee plates and even on Bolter cases or vehicles.

Prime Helix[]

Prime Helix variants

Prime Helix variants

The Prime Helix is the emblem of the Apothecaries of a Chapter.

The bright red design represents both the gene-seed itself and, to some extent, the sacrifice every Space Marine is prepared to make to ensure the Chapter's future.

Crux Terminatus[]

Terminator Honours variants

Crux Terminatus variants

This is one of the most famous of all Space Marine icons. Only the honoured 1st Company Veterans of a Space Marine Chapter fight in suits of Terminator Armour and wear this badge.

The symbol has various forms and designs but all versions are carved from great chunks of stone.

Within each badge is bound an infinitesimal fragment of the suit of Power Armour worn by the Emperor during His climatic battle with the Arch-traitor Horus over ten millennia ago high above Terra.

Sergeants and Captains bear modified versions of the design to signify their rank and authority.

Smaller representations of the Crux are frequently worn by the Veterans when they fight in standard Power Armour to display their elite status. These small, metallic icons can be hung from banner tops, weapons and belts.

Service Studs[]

Service Studs variants

Service Stud examples and Service Studs (close-up)

Service Studs are small metallic rivets that are attached directly to an Astartes' cranium to record his years of service to his Chapter.

A single stud records, 10, 50 or 100 Terran years of service depending on its design and the Chapter traditions.

The awarding of service studs is described in the Codex Astartes but is not set out as an official requirement or regulation of the Chapter.

In recent centuries the awarding of service studs has been on the decline and fewer Chapters continue the practice.

Veteran Marine of the Storm Wardens Chapter with facial tattoos.

Tattoos are not official Chapter honours but traditional markings derived from a Chapter's ancient practices. Some tattoos may even be vestiges of pre-Space Marine tribal markings or hive city gang affiliations.

Space Marines are recruited from hundreds of different human cultures across the galaxy so it is no surprise to see this diversity reflected in some Astartes retaining the tattoos, scarification or warpaint of their homeworld's dominant peoples.

Machina Opus[]

Machina opus

The Machina Opus

The Machina Opus is the mark of a Tech-priest Adept.

It is awarded to each Techmarine after he completes his mysterious training with the Adeptus Mechanicus on Mars in the science and technology of the Imperium.

Bearers of the Machina Opus are accorded great respect by the Tech-priests and they alone are allowed free passage through the Red Planet's Ring of Iron and into the great workshops of the Martian hive cities and forges.

Raptor Imperialis[]


The Raptor Imperialis

The Raptor Imperialis was the first symbol used to represent the Imperium of Man during the Unification Wars.

During the Great Crusade, after the adoption of the Imperial Aquila, it marked out a Terran-born veteran Space Marine who had once fought alongside the Emperor Himself.

Army Campaign Badges[]

Army Badges

Various Army Campaign Badges worn by the forces of the Adeptus Astartes

Space Marines often find themselves going into battle alongside other Imperial forces. The massed ranks of the Astra Militarum form the major portion of any allied contingent of Imperial forces and include huge tank divisions as well as enormous numbers of foot soldiers.

When an army of the Imperium goes to war it is standard practice for the Imperial Commander or commanding general to choose a symbol to act as a campaign badge in accordance with the regulations set down in the Codex Astartes.

This "field sign" is known as the Army Badge and serves to identify all the troops and equipment that are operating under a single command for a single campaign and helps with recognition of friendly units on the field of battle. The Army Badge is painted on Space Marine Power Armour and Astra Militarum vehicles alike.

Each time a Space Marine applies the badge the recipient receives a blessing from the company Chaplain or from an attached member of the Imperial Ecclesiarchy if serving alongside one of the other Imperial armed forces.

The Army Badge is deliberately designed to be quite straightforward and is an instantly recognisable symbol that functions as a battlefield identification. Space Marines generally apply the Army Badge to their right leg greave.

The Army Badge is generally used for the duration of a single campaign and is removed or replaced at the successful conclusion of the campaign. If a squad, regiment or indeed an individual warrior has performed exceptionally in the campaign, the Army Badge may be incorporated onto their armour, uniform or heraldry as a permanent honour.

This is particularly true of banners and standards and many of the lavish designs seen on Chapter, company and individual Astartes banners are, in part, derived from the Army Badges of previous campaigns.
