Astra Militarum

Astra Militarium


The Astra Militarum is the main fighting force of the Imperium of Man. Made up of billions of men and women, and supported by countless light and heavy vehicles, artillery, and heavy weapons, the Astra Militarum overwhelm enemy forces by sheer weight of fire and body count.

If the Adeptes Astartes are the scalpel, then the Astra Militarum are the hammer.

  • Grinding Advance: The Astra Militarum uses the size of their forces to smash through their opposition, while also enabling them to be able to take huge losses.
  • ‘Pound them to Dust!’: Regiments of guardsmen are traditionally supported by an array of vehicular support, iconically heavy weapon platforms, tanks and mechanized cavalry, which they use to rain fire down upon their foes.
  • ‘Forwards, for the Emperor!’: Guardsmen are often supported and disciplined by Commissars, political officers who use any means necessary to maintain order and morale.
