List of Astra Militarum Regiments

This is a list of official Imperial Guard Regiments created by Games Workshop. It does not include any fan-created Regiments, though it does include the Renegade Regiments of the Imperial Guard as well as those Imperial Guard Regiments considered Excommunicate Traitoris by the High Lords of Terra whether they serve the Dark Gods or not. This is not a complete list as not every Imperial Guard Regiment in existence in the Imperium of Man is known.

Please note: fan-created Chapters must be posted at the Warhammer 40k Fanon Wiki - Imperial Guard Regiments and not on this page.

13th/5th Imperial Army
The 13th/5th Imperial Army, also known as "Hylgar's Hellraisers," was an Imperial Army formation according to obscure but extensive records. Although recorded in Imperial records as an Imperial Guard formation of the 41st Millennium active between 975.M41 and 988.M41, many of its elements are in fact highly archaic and more reminiscent of an Imperial Army regiment of the Great Crusade and Horus Heresy periods. What is known is that its regimental name designates it as the 13th Imperial Army of the 5th Quadrant, and that it was commanded by Julius Hylgar, a senior member of the Administratum as well as the holder of several other Imperial titles, such as "Cardinal of Kolarne" and "Grand Marnier Militaris." This latter title was one used by the Administratus Militarium, the Administratum's martial branch (a possible antecedent of the current Departmento Munitorum).

13th/23rd Tiger Lizards
The 13th/23rd, also known as the "Tiger Lizards," was a regiment of the Imperial Guard. They were known to have fought against the Tyranids under the regimental command of Lieutenant Colonel Uskra, who commented on his regiment's ability to attack in perfect coordination.

13th Penal Legion
The 13th Penal Legion, also known as the "Last Chancers," is a special regiment composed of Imperial criminals and convicts. All the men and women of the Last Chancers are hand-picked by the fiercely uncompromising Colonel Schaeffer for the performance of suicide missions on behalf of the Imperium of Mankind throughout the galaxy. The convicts are given a "last chance" by Schaeffer to be forgiven of their crimes in the eyes of the Emperor of Mankind and this is achieved by receiving an Imperial pardon from the Colonel. These pardons are awarded only to those members of the regiment who survive a number of military operations determined by Schaeffer. Colonel Schaeffer personally pardons all those who die during an operation posthumously.

17th/21st Tiger Lizards
The 17/21st Tiger Lizards were an Imperial Army formation that existed as early as the 30th Millennium, possibly during the Unification Wars era. Their presence was recorded in the Codicium Arkathalor (a fragmentary record of the Imperial campaigns conducted in the Pandora Sector. The Tiger Lizards were recorded as one of at least two regiments made up of "split" formations, where two wholly individual, but badly mauled regiments were merged into one battle-effective fighting regiment (they were merged with the 61st/320th Orenian).

Armageddon Ork Hunters
The Armageddon Ork Hunters are a specialised unit of Imperial Guard soldiers formed in the wake of the Third War for Armageddon in 998.M41. They were created to conduct xenocidal campaigns throughout the equatorial jungles of the Hive World of Armageddon in an attempt to rid them of the Ork presence that had taken root there. Specialising in guerrilla tactics and jungle warfare, the Ork Hunters fight their feral enemy on their own terms, and have become extremely adept at their savage purpose. Their feral appearance and coarse manner has led to the Ork Hunters being regarded as little better than the Greenskin scum that they hunt and have earned them the enmity of many Imperial Guard regiments stationed on Armageddon.

Armageddon Steel Legion
The Armageddon Steel Legion are the regiments of the Imperial Guard that fight as mechanized infantry alongside Chimera armoured personnel carriers in defence of the strategically-located Imperial Hive World Armageddon and its surrounding star systems. Armageddon, located in the Segmentum Solar, was a planet blighted and poisoned by millennia of heavy industrial output, though it was also a major manufacturing centre. In the 41st Millennium, Armageddon became a constant battleground between the Imperial Guard's Steel Legion Regiments and the countless Ork hordes of the Warboss Ghazghkull Mag Uruk Thraka.
