Ultramarines)), and your army cannot contain units with more than one different Chapter keyword.

You are, however, prevented from mixing units from across different Chapters (or combining them with some of the Epic Heroes in here – such datasheets have a second Faction keyword alongside Adeptus Astartes (e.g. There’s also nothing stopping you from using the Space Marines’ detachment (the Gladius Task Force which we’ll talk about below) and playing a Blood Angels army (including your unique datasheets, like Sanguinary Guard) which uses it and its rules, but you don’t stack the rest of the stuff on top. Unlike early 8th edition, those factions are not standalone – you will still need the Space Marines one for most of your unit choices, and they all share the “Oaths of Moment” faction rule below.

The majority of the supplements have gone away and their characters are folded back into this index, leaving just the five most different Chapters – Blood Angels, Dark Angels, Space Wolves, Black Templars and Deathwatch – with indexes of their own. That situation is substantially different in 10th. All of these rules piled on top of each other to combine in various different ways, and meant that different Chapters played radically differently. These supplements each contained a unique set of faction rules as well as extra Stratagems, Relics, and datasheets – though some (Space Wolves) had more of that last thing than others (Iron Hands) – but you still needed the base Codex: Space Marines to play them, and used nearly everything in it. This changed after the second Codex: Space Marines in late 8th edition, from which point on there was an additional range of Chapter Supplements – 10 of them! – covering the 9 ‘First Founding’ Chapters, plus Deathwatch. At the beginning of 8th edition most Marines were in the main Codex and then a few other Chapters had their own completely separate books. It’s worth highlighting this right at the start, because 10th edition treats sub-factions in a different way to how 8th and especially 9th edition did, and this is most impactful for Space Marines. Not only is the faction huge in its own right, but there are a number of sub-factions based on their most famous Chapters.

Their index is the biggest of the bunch, packed full of datasheets for (nearly) every unit in their gigantic range, plus some new ones like the Ballistus Dreadnought and the Apothecary Biologis. The Space Marines are the iconic faction of Warhammer 40,000, and take their traditional place in the launch box facing off against the Tyranids of Hive Fleet Leviathan.
