The Imperial Guard

The Imperial Guard, also known as the Astra Militarum in High Gothic, are the ground forces of the Imperium of Humanity. Countless billions of soldiers from every planet of the Imperium fight and die on thousands of worlds across the galaxy, often hundreds of light-years from home. Life in the Guard is bloody, gritty, work, few survive service as they fight for the very survival of Humanity against the Imperium’s foes.

Five Things To Note About the Imperial Guard

  • They are not local. First-line defence of a planet against internal and external threats is carried out by Planetary Defence Forces, local levies raised by the Planetary Governor from among the population. Imperial Guard are almost always deployed away from their home planets.
  • They are Humanity’s Fighting Elite. While it is easy to think of the Guard as being used as cannon fodder by uncaring Imperial commanders, and it is true that they are simply -numbers- to many. The majority of Imperial Guard represent the cream of the crop of humanity’s fighting forces and while the vast majority are basically-equipped infanteers or armoured units – there are several elite regiments focused on stealth and special operations
  • They are diverse. While all fall under the banner of the Guard, each Regiment’s traditions, command structure, equipment and ranks are unique. Rank across different Regiments is a difficult and delicate business to work out, and even the size of a Regiment can differ wildly from planet to planet.
  • They do not have ships. The Imperial Guard do not have their own Warp-capable vessels, and apart from some in-atmosphere fighters and small transports, rely entirely on the Imperial Navy to fly anywhere
  • They do the fighting. While the Imperium likes to tell dashing tales about the superhuman Astartes, and the faithful Sorors, it is the Guard who are involved in 99% of all of the Imperium’s engagements. They own their title as the Hammer of the Imperium, and although other forces may steal the credit, the Guard are responsible for the majority of its major victories.


The History of the Imperial Guard in the Prosperitas Sector

When Warmaster Jascinta Durovera’s Crusade began in 013.M41, the Imperial ships who came to relieve her carried in their holds thousands of Guard forces to suppress the rebellious worlds of the Sector. These forces were soon exhausted in the decades and centuries that followed, however, and with world after world falling compliant before the Warmaster’s sword, all were soon called upon to provide a tithe of troops to the Crusade.

Today, the bulk of the Imperial Guard forces subordinate to the Crusade are composed of locally raised Regiments. As a result, none can claim seniority dating back more than four or five centuries – a very brief history indeed in Guard terms.

High Command

  • The supreme commander of all Imperial Guard forces is the Lord Commander Militant, one of the High Lords of Terra.
  • The Lord Commander Militant is assisted by five Lord Commanders Segmentum, one for each of the five corners of the Galaxy. The Prosperitas Sector falls under Segmentum Obscurus.
  • At the Sector level and below, Guard forces might be commanded by a Lord General Militant. In sectors with an active Crusade, such as the Prosperitas Sector, the forces fall under the overall command of the Warmaster.
  • The General Staff, made up of high-ranking Guard and Navy officers, assist the Warmaster in the running of the Crusade. The Prosperitas Staff are based at Crusade High Command on Polarnus Station.
  • The four Salient Commanders of the Sector command mixed Battlegroups made up of combined Guard, Navy and specialist forces, each assigned to one of the Crusade’s Salients.

Rank and Status in the Regiments

With forces drawn from every conceivable planet and culture in the Sector, rank across Regiments is a tricky business. One trooper’s Colonel might be called a Castellan-Major elsewhere; a Sergeant might command thirty troops in one regiment, but act as advisor and aide to a junior officer in another. Insignia is just as variable, and many an unwary trooper has been caught out with a tongue-lashing for saluting the wrong number of pips on a sleeve.

Regiments assigned to the Salients each fall under their own commander – usually called a Colonel. This senior officer leads their Regiment in the field and takes their orders directly from the Salient Commander.

Below the commander, regiments are led by Officers. The method of selecting these officers varies wildly; some Regiments accept only officers from high-status families, some select based on aptitude and merit, some promote the most senior and promising soldiers into these roles and others have stranger and more unique traditions. Officers of a Regiment are often referred to as holding the Emperor’s Commission, a document which entitles them to issue legal orders to any soldier. Typical Prosperitan rank names for regimental Officers, sometimes called include Lieutenant, Ensign, Cornet, Fo-Chennard, Breedman, Subaltern; Captain, Toran, Chennard, Qayid; Major, Jakaran, Commandant, Ceanfort. Officers ranked “Captain” who serve or travel aboard Imperial Navy vessels are usually given a “courtesy promotion” to the next rank up while aboard, to avoid confusion with the vessel’s master.

Each Regiment will be divided into sub-units, whose names and command structure are as variable as their homeworlds. One classic pattern has each Regiment divided into four Companies, each led by a Major, and each Company divided into three Platoons, each led by a Lieutenant or Captain; but to the despair of the Munitorum, this pattern is by no means universal. The internal organisation of a Regiment is entirely in the gift of the Colonel, bound only by her whim and the traditions of her homeworld.

Some Officers find themselves detached from their Regiments to serve as aides and functionaries on the Staff of their Salient Commander or at Crusade High Command, referred to as “Staff Officers”. These officers do not command troops directly, but instead spend their time planning and shaping the next battles of the Crusade. Staff service is seen as boring, lacking glory, but a positive career move for a young officer looking for higher rank.

Soldiers who show particular aptitude are selected to become Non-Commissioned Officers (NCOs). These soldiers are not usually saluted or entitled to the same privileged as a Commissioned Officer, but are promoted by dint of seniority and expertise to leadership positions. They act as subordinate commanders and specialists for the Regiment, advising and assisting the officers. Very senior NCOs can rise to high status, advising Colonels and Generals with the benefits of their decades of experience on the battlefield as Regimental or Command Sergeants-Major. In the Prosperitas Sector, common NCO ranks include Corporal, Arif, Sergeant, Sairsint, and a thousand variants; Lance-Corporal, Colour-Sergeant, Corporal-of-Horse, Colour-Arif…

Finally, Troopers make up the billions-strong forces of the Prosperitas Crusade. Recruited from worlds across the Sector. The majority of Troopers recruited for the Guard will be drawn from the cream of the crop of their worlds defence forces, or from volunteers, the Guard would -prefer- to take willing and quality soldiers where it can find them.

In rare circumstances where a force is needed to be raised with some rapidity, the Imperium will consider mass conscription, but this is a rare choice, and such regiments (referred to as ‘Conscripts’ or ‘Whiteshields’) are often raised from prisoner populations on penal worlds and are often obliterated in meatgrinder campaigns where they are used to slow enemies while more elite Regiments and Imperial Forces are brought to bare.

Although the Departmento Munitorum is eager to provide endless propo-vids and posters advertising the benefits of pay, glory and pensions available to those who serve in the Guard, most will never return to enjoy them. While some worlds like Shadowglow consider Guard service a great honour and run extensive selection events to send only their best and brightest to the stars, for many others though, selection for duty is the promise of never seeing home again and dying under alien suns. The rank of Trooper is common, but soldiers might be called Private, Fusilier, Guard, Askar, Recruit, Earcach; and in some specialist regiments, Signaller, Sapper, Crafter, Gunner, Tanker and so on.

People of Note

  • Warmaster Armelius Durovera. In overall command of the Prosperitas Crusade, the Warmaster and Sector Governor directs his forces from his Flagship, the Exorcist class Grand Cruiser Word of Despite.
  • Lord-General Militant Ruprecht Janus. A dogmatic, perfectionist general, Lord-General Janus is the son of the famed war hero Heta Janus. His mother died while personally leading a suicide charge on an enemy General’s command vehicle on Kelper Prime. He commands Battlegroup Diomedes.
  • Captain-General Brianna Twine. An aggressive, idealistic commander from old Imperial Aristocratic stock, the Captain-General is in joint command of Fleet Arm Geryon. She earned her stars as the commander of a Leman Russ tank regiment, and has all the carefree arrogance typical of a senior cavalry officer.

Regiments of Note

Some of the more notable Guard regiments of the Prosperitas Crusade are listed here, with a brief outline of their traditions and customs.

  • 18th Amenophis Light Infantry. Raised from the desert Hive-World of Amenophis, these robust infanteers have a reputation for being fearsome in close combat, using light boarding shields and short khopesh swords to devastating effect in the claustrophobic confines of urban Hives and aboard ships.
  • Helaerus Reconnaissance Regiment. Boasting among its veterans the retired General Halina Chenau, now Governor of Macharion CDXI, the Regiment [Record Incomplete]
  • Kelper Engineer Regiments. Famed across the Sector for their proficiency with ambush tactics and improvised explosives, the Kelper Sappers often send bright instructors to teach at the Guard academies for sappers, ammunition technicians and explosive ordnance disposal specialists.
  • Korimesta. Fielded from the claustrophobic hive-world of Korimesta, the Korimestan regiments are specialists in close-quarters combat and assault tactics. The disgrace of the mutiny of the 89th Korimestan Light in 592.M41 hangs as a heavy pall over the Regiments, whose remaining Colonels are determined to regain their honour in the field.
  • Letiferan First Armoured. A well-regarded armoured cavalry unit, the First are equipped with heavily-modified Chimaera-pattern tanks which specialise in chemical and biological warfare. The boast of the Letiferan troops is that they have a “suitable vintage for every occasion and any company”. The regiment’s greatest record is a minor skirmish on the Tenebris border, where a single well-mixed shell was recorded as killing six thousand, three hundred and eight combatants, two thousand civilians, all livestock on the western continent and the grain crop for the next four decades.
  • 18th Merewald Fusiliers. Despite the backwards Merewaldian attitude to technology, the Fusiliers have a strong reputation across the Subsector. Their excellent foot drill, line discipline and courage under fire have been remarked upon by Crusade High Command as the pinnacle of everything a light infantry regiment should hope to achieve. Their distinctive bright red uniform tunics and tan topi helmets are a sight to stir Imperial pride and piety among civilians from the Rimward Marches to the Tertius border.
  • Vallum Regiments. As inhabitants of a Fortress-World under constant Enemy attack, every able adult on Vallum is a member of one of the regular or reserve Regiments. The Vallum regimental speciality is the savage defense of small, easily mobile defensive positions; a great deal of their early training was conducted by Raivan instructors borrowed from the Shadowglow regiments, and this shows in their keen grasp of insurgent tactics and ruthless exploitation of enemy weaknesses.
  • Strayvian Regiments. Raised from the once-bountiful agri-world of Strayvia, the Regiments are now homeless after the planet’s destruction by virus-bomb in 577.M41. The Strayvian regiments remain committed to Battlegroup Hesperidus, and are a notoriously difficult to command; bitter, angry and frequently insubordinate after the loss of their homeworld, they are nevertheless battle-hardened and highly competent soldiers who are often selected for the most demanding missions requiring strike forces of fast-moving and self-sufficient light role infantry.
  • Shadowglow Regiments. The Raivans of Shadowglow, armed with their feared “desert knives” – the local term for Guard issued swords – have a reputation for military might and piety. The Regiments are seen as a prestigious and honourable career for a young Raivan; in many towns, all healthy adults compete in arduous physical trials across the desert hills, with the fittest winning the right to volunteer for recruitment. Some senior Raivan officers quietly boast that given their ancestors’ history of millennia-long insurgency against the Enemy, the Shadowglow Regiments should technically be given seniority over all other Imperial Guard regiments in the Sector – but this position rarely gains any traction when spoken in the mouth of an abhuman.
  • Persephon Regiments. The planet of Persephon has spent many years of near constant war with the Sector’s only substantial greenskin population – Persephon Regiments are characterized by a somewhat fanatical devotion to their planet, and their patron saint St Leonidas – many Persephonian Troopers view their service in their Guard as the way by which they will earn the Crusade the breathing space to finally cleanse their planet of the Greenskin Threat.
  • Caudican Regiments. Dispossessed and orphaned after the destruction of their homeworld Caudica in 582.M41, the Caudican Regiments are still awaiting permission from the Departmento Munitorum to recruit from other worlds. With no source of casualty replacements, they face disbandment or amalgamation before the decade is out if permission is not forthcoming soon.
  • Burisalis Armoured Regiments. The training ground for the Crusade, Burisalis Prime fields its own tank regiments, expert in open armoured warfare. The disgraceful mutiny of the 10th Burisalis Armoured in 592.M41 has severely weakened the Regiments’ reputation in recent months.
