Dead Men Walking (Warhammer 40,000)

When the necrons rise, a mining planet descends into a cauldron of war and the remorseless foes decimate the human defenders. Salvation comes in an unlikely form - the Death Korps of Krieg, a force as unfeeling as the Necrons themselves. When the two powers go to war, casualties are high and the magnitude of the destruction is unimaginable.

Read it because
The Death Korps are unlike any other Astra Militarum unit – batch-bred, born to fight and completely indoctrinated to their cause. See how effective that can be in this storming story.
