Warhammer 40,000: Astra Militarum Books in Order

Warhammer 40,000: Astra Militarum stories put ordinary human soldiers at the centre of a galaxy built for monsters, superhuman warriors, and impossible wars. The Guard has tanks, artillery, aircraft, and huge regiments, but its troops are still human. They get tired, miss information, worry about supplies, and are often ordered into places where survival looks unlikely.

Peter McLean's Guard fiction usually works at that close level. Baphomet By Night follows members of the Reslian 45th on garrison duty after a Chaos war, when the danger turns out not to be as finished as the official report suggests. No Hero and Blood Sacrifice return to the same broad world of frontline soldiers, showing how the damage of one campaign follows people into the next.

Nobody gets a quiet posting for long.

Lightning Run shifts to the Imperial Navy side of the same war effort. Valkyrie pilot Salvatoria Grant is given a mission to transport a vital general through a collapsing war zone. The story keeps the stakes immediate: a crew, an aircraft, a route that is no longer safe, and a job that cannot simply be abandoned.

This part of the setting is ideal for readers who want military science fiction without needing to begin with the biggest names in the Imperium. Guard stories make room for squads, pilots, medics, officers, and penal troops. They also show the unglamorous side of war, from wrong equipment and bad intelligence to the long wait before something starts shooting.

There is no single Astra Militarum reading order across all authors. Start with the book or story that matches the kind of campaign you want. Choose Baphomet By Night for haunted garrison tension, Lightning Run for aerial action, or a larger collection such as Imperial Guard Omnibus: Volume One for several different regiments.

This page gathers those routes in one place, with summaries and series notes to make the vast Guard catalogue easier to navigate.
