The 9th edition book was designed to modernize the Astra Militarum, bringing them in line with the high-powered environment of late 9th edition play.
For narrative players, the book included extensive rules for modeling a force's campaign, including logistics management and awarding medals to heroes. Notable Changes from 8th Edition
With the release of Warhammer 40,000 10th Edition in June 2023, the 9th Edition Astra Militarum Codex is no longer used for standard matched play. It was replaced by a free index at the start of the edition, which remains the primary way to play the army until the full is released. Looking for the PDF?
