HORUS HERESY: LIBER AUXILIA (ENG, 2025)

The steadfast Solar Auxilia are among the finest human soldiery of the 31st Millennium – surpassed only by the Space Marine Legions. They carried much of the burden of the Great Crusade, and in the Horus Heresy, they fight in their billions, both for and against the Imperium they helped build.

This book is the essential guide for commanding a Solar Auxilia army in Warhammer: The Horus Heresy. It provides a complete overview of their organisation, doctrines, and methods of war – from infantry cohorts to heavily armoured war machines.

Focused on discipline, numerical superiority, and coordinated formations, the Solar Auxilia offer a distinct playstyle compared to elite Astartes forces.

On the Battlefield

The Solar Auxilia excel through structured formations, strong defensive lines, and access to powerful support weapons.

This book introduces Doctrines and Detachment options that define how your forces operate, enabling everything from methodical advances to overwhelming supporting firepower. The combination of infantry and heavy equipment creates a flexible but discipline-driven army.

Rules for Legiones Auxilia also allow your cohorts to be bonded to specific Space Marine Legions, unlocking additional tactical synergies.
