Other Warhammer 40,000 collects two Dan Abnett titles from 2007 that sit outside his main Warhammer 40K series. Tactica Imperialis is a lore compendium written in the style of an in-universe military manual, providing background on the tactics and forces of the Imperium of Man. Brothers of the Snake is a novel following the Iron Snakes, a loyalist Space Marine chapter based on a world called Ithaka.

Brothers of the Snake is structured as a series of linked short stories rather than a conventional novel, each covering a different mission undertaken by the same squad over decades. This episodic format suits the material well, showing how Space Marines operate across a long span of time and multiple theatres of conflict. The Iron Snakes are a distinctive chapter with a culture drawn partly from ancient Greek warrior traditions.

Both volumes are listed in the reading order table below. Readers with an interest in Warhammer 40,000 lore beyond Abnett’s Gaunt’s Ghosts series will find these books a useful complement to his wider output in the setting.
