Tyranids emerge from the depths, Dark Angels fight against the odds, and Chaos Space Marines get psychic in their new June 40k detachments!
These new Warhammer 40k detachments bring serious firepower, cutting-edge tech, and elite warrior tactics to the tabletop. Tyranids got Subterranean Assault. Dark Angels unlocked Wrath of the Rock. And last but not least, the Chaos Space Marines have unleashed the Cabal of Chaos in their new detachments.
Each of these factions also gains a fresh detachment rule, enhancements, and tactical stratagems that change the way they play. So, whether you want an endless hail of bullets, emerging from the depths, or lone warriors carving through enemy lines, this update has something for you.
Well, unless you don’t play one of these factions, that is…
More 40k Detachments Roll In
These aren’t the only detachments on the way, either. Games Workshop said that there would be new quarterly detachment drops for factions for the “rest of the edition.”
Which almost guarantees that we will see 11th edition at some point in the near future (as most rumors point to the summer of 2026.) So, from the looks of it, there may be a lot more detachments on the way on top of the ones we already saw for Grotmas in 2024.
Tyranids– Subterranean Assault Detachment
We all know Tyranids love surprise attacks, and this detachment turns the ambush tactics up to 11. The Surprise Assault rule gives Tyranids re-rolls on Hit rolls of 1.
Then, when Burrower units like Trygons or Mawlocs arrive from reserves, they place Tunnel Markers—perfect beacons for a deadly ambush.
Units can then emerge near these markers, ready to strike from unexpected angles.
To make those ambushes count, Adaptive Optimisation gives key monsters the Synapse keyword, enabling control and coordination, while Replenishing Swarms lets units heal or even bring back lost models.
Stratagems like Tunnel Network and Retreat Below allow you to reposition units mid-game or slip them back into Strategic Reserves.
Swarming Assault gives nearby Tyranids re-rolls to charge, while Enfilading Emergence lets arriving units hit harder with Sustained Hits and Ignore Cover.
Enhancements reinforce this burrowing playstyle. Tremor Senses gives you a pre-game redeploy, Synaptic Strategy allows a free Rapid Ingress, and Vanguard Intellect offers Deep Strike flexibility on any early turn. The Trygon Prime upgrade turns your beast into a Synapse leader with boosted melee stats.
Why This Works
This detachment is all about control, flexibility, and striking from the shadows. Tunnel Markers and redeploys give you superior battlefield mobility, while Stratagems and Enhancements make sure your units hit hard when they show up.
You can heal, reposition, or retreat at will, keeping the opponent guessing. Whether you’re pouncing with a Trygon or unleashing swarms near an objective, Subterranean Assault rewards clever timing and coordinated strikes—perfect for Tyranid players who like to stay one step ahead.
Dark Angels– Wrath of the Rock Detachment
We all know the Dark Angels are unshakable on the battlefield, and this detachment turns that stoic resilience into a brutal tactical edge. The Dutiful Tenacity rule makes their infantry and mounted units tougher to wound against high-strength weapons, letting them hold ground through withering fire.
To make that resilience count, Tempered in Battle keeps nearby units in the fight with Leadership and Battleshock re-rolls, while Ancient Weapons lets characters carve through enemies with powered-up melee attacks.
Deathwing Assault gives elite units early Deep Strike options, and Lord of the Ravenwing ensures fast-moving bike units can reliably advance and charge.
Stratagems give you a suite of defensive and reactive tools. Armour of Contempt shrugs off Armor Penetration. Lion’s Will boosts Objective Control and Hit rolls in close combat. Tactical Mastery lets Ravenwing units charge after falling back.
For firepower, Relics of the Dark Age supercharges your ranged attacks, and Leonine Aggression allows surprise counter-charges at the end of your opponent’s turn. Inescapable Justice even lets you retarget your Oath of Moment mid-battle to keep pressure on.
Why This Works
This detachment is all about unbreakable defense and precise, punishing counters. Dutiful Tenacity and Armour of Contempt blunt your opponent’s offense. Relics of the Dark Age and Ancient Weapons make your return fire and melee hits devastating.
Pair Leonine Aggression with Deathwing Terminators for brutal counter-charges. Tactical Mastery to keep Ravenwing constantly in motion. Dark Angels don’t just endure—they dismantle their foes one calculated strike at a time.
Chaos Space Marines- Cabal of Chaos Detachment
We all know Chaos Space Marines thrive on dark power, and this detachment turns warp-fueled warfare up to 11. The Empyric Wellspring rule lets you empower units every time they make a Dark Pact—either boosting the Strength of ranged weapons if near a Psyker, or improving melee AP if near a Daemon Prince.
To make those boons count, Infernal Avatar supercharges Daemon Princes into close-combat monsters. Then, Mind Blade gives deadly melee weapons the Lance ability, helping them wound tougher foes.
Touched by the Warp upgrades any model into a Psyker for maximum synergy, and Eye of Z’Desh adds Scouts for early-game positioning plays.
Stratagems bring both pain and durability. Baleful Blessing grants 5+ Feel No Pain against mortal wounds. Then, Shroud of Chaos gives nearby units Stealth, keeping your lines safe.
Need more pressure? Mutation’s Curse dishes out mortal wounds at range. Unholy Haste lets your units Advance and Charge, warping across the battlefield unexpectedly.
Soulseekers pierce defenses with Ignore Cover. No Rest in Death lets you heal or even return fallen models to the fight.
Why This Works
This detachment is all about power through proximity and tactical flexibility. Stack Empyric Wellspring buffs to adapt your offense on the fly. Shoot harder or stab deeper depending on positioning.
Enhancements like Infernal Avatar and Mind Blade turn characters into monsters. Soulseekers and Mutation’s Curse soften targets for your main force.
Pair Shroud of Chaos with frontline units to survive return fire, or Unholy Haste with melee squads for surprise charges. Chaos doesn’t just fight—it warps the battlefield to its will.

Final Thoughts on How These Detachments Change the Meta
The Subterranean Assault, Wrath of the Rock, and Cabal of Chaos detachments bring powerful new strategies to the tabletop. While Tyranids go all-in on maneuverability, Dark Angels show they can fight against any odds, and Chaos turns into psykers.
So if you like raining bullets, submerging all over the battlefield, or fighting against the odds, these new detachments shake up army compositions in the best way possible.
