Best Chaos Space Marines detachments 11th edition · ranked by winning lists
Every Chaos Space Marines detachment, ranked by how many winning Chaos Space Marines lists played it, with what it changes on the dice in our own words and the units it lifts most. Too few lists to judge: 1 winning Chaos Space Marines list, August – September 2026, so the order is a hint, not a verdict.
A winning list here is one that finished in the top quarter of its event. An army can take up to three detachments, so the shares add up to more than 100%.
