Marneus Calgar, Cato Sicarius, and the Victrix Honour Guard return with official new 40k Ultramarines codex rules and models!
A new dawn rises over Ultramar, and it’s looking pretty heroic. Marneus Calgar, Cato Sicarius, and the brand-new Victrix Honour Guard kits are available to grab, and people are itching to throw the models on the table.
Instead of releasing another supplement, Games Workshop dropped a PDF of their new 40k rules, and there’s a lot here for Ultramarines codex fans to get excited about.
Ultramarins Codex: Blade of Ultramar Detachment
Updated on November 13th, 2025, by Rob Baer with the latest rules and detachment updates.
Detachment Rule: Mastered Doctrines lets you shift between Devastator, Tactical, and Assault every Command phase, so your army is always operating in the mode that punishes your opponent the most. Advance and shoot, fall back and charge, or sprint into melee with zero hesitation, all depending on what the table demands.
Playstyle: This new Ultramarines Codex detachment rewards smart sequencing, reactive buffs, and keeping your opponent guessing. One turn you are a mobile gunline, the next you are counter-charging like you planned it three turns ago.
Enhancements:
- Get a tougher warlord with a 2 plus save and a built-in shrug.
- Make a melee monster swing harder under Assault Doctrine.
- A battlefield nerd who turns Tactical Doctrine on like a light switch.
- Veteran gunline leader handing out Sustained Hits and turning Devastator into full throttle shooting.
Stratagem Highlights:
- Armour of Contempt and Tactical Foresight make you surprisingly tanky at key moments.
- Courage and Honour gives melee units the extra punch they need.
- Exemplary Vigilance grants Ignore Cover and extra AP against ranged pressure.
- Ultramarian Adaptivity and Practical Tactics let you shift Doctrines or reposition on demand, turning every phase into a chance to outmaneuver your opponent.
This detachment plays exactly like Ultramarines fans want: controlled, reactive, and always one decision ahead.
Marneus Calgar Rules Level Up
The big man himself returns with a fresh battlefield twist. This version of Marneus Calgar rules can now Deep Strike and join Terminator or Assault Terminator squads, giving your Ultramarines codex a serious teleporting punch.
But bigger, he can act normally after falling back or advancing, so throw him into the fray and move wherever you need.
Pairing him with the Crux Terminatus box dropping alongside him just makes sense. Calgar leading a wall of blue-clad Terminators straight into the fray? That’s the kind of cinematic moment we all want to see on the tabletop.
Worth mentioning: this isn’t a replacement for his Gravis armor version. You can run either one, just not both in the same army.
Cato Sicarius 40k Ultramarines Rules
New Cato Sicarius rules are here, and his Talassarian Tempest Blade now gives players real flexibility. He can pick from three combat styles: one for cracking elite enemies, one for cutting down hordes, and one for dueling champions. It’s a flavorful way to represent his duelist prowess.
He’s also rocking a brand-new ability to replace Lead From the Front and can now hang out with the Victrix Honour Guard, even if Calgar is already tagging along. The boys in blue clearly know how to coordinate with these new Ultramarines rules.
Victrix Honour Guard Rules are Tough and Loyal
Speaking of the Honour Guard, these new Vitrix Honour Guard rules are brutal. Each has four wounds, a built-in damage reduction ability when led by Calgar or a Captain, and the new “Surge move” that lets them lunge toward the nearest enemy when one of their comrades goes down.
So, not only are they hard to kill, but every casualty just makes them angrier.
They’ve got Objective Control 2, meaning they can muscle other elite units off points with ease. You can field them in squads of three or six, and while the datasheet technically allows for one, the points cost makes it clear that three’s the minimum.
The Chapter Champion and Chapter Ancient are back, too, both tagged as EPIC HEROES, which means only one of your squads can take them.
The Champion hits like a truck with Precision and Twin-linked on his blades of honor, while the Ancient’s banner gives the unit a once-per-game combat boost. Stack those buffs, and your opponents are going to feel it.
.
There’s also a small update for the Captain with Jump Pack, officially making the chainsword-and-storm shield combo legal in matched play.
Final Thoughts on New Ultramarines Codex Rules
Between Calgar’s redeployment flexibility, Sicarius’ new dueling tricks, and the Honour Guard’s mix of durability and aggression, Ultramarines Codex rules are giving players some real depth back into their lists.
Plus, maybe best of all, when the pre-orders arrive, you can start playing right off the bat.
