Imperial Guard Regiment Name Generator

Astra Militarum regiments follow a naming formula that is easy to spot once you know it: homeworld first, then the regiment's number, then the kind of troops it fields. Cadian 8th Shock Troops, Death Korps of Krieg 143rd Siege Regiment, Valhallan Ice Warriors 597th and Elysian Drop Troops 23rd all work this way. The homeworld tells you the regiment's culture and fighting style, the number tells you how many foundings that world has raised (Krieg and Cadia run into the hundreds), and the troop type tells you what turns up on the tabletop: armoured, mechanised, light infantry, rough riders, siege, grenadiers, drop troops or penal legion.

The second half of a good regiment name is the nickname. Regiments that survive long enough earn an epithet, usually in quote marks after the number: Catachan II 'Catachan Devils', Necromundan 8th 'The Spiders', Cadian 122nd 'Gaunt's Own'. Some regiments are known by a single proud title, like the Tanith First and Only, the Volpone Bluebloods or the Savlar Chem-Dogs, and veterans will use the nickname far more often than the official designation.

This list mixes canon regiments from the codexes and Black Library novels, included to show the style, with hundreds of original homeworlds, numbers and nicknames, plus abhuman auxilia and Tempestus Scion regiments, so you can name an entire army group.
