New Astra Militarum Detachments in Armageddon

Astra Militarum Gets a Serious Armoured Upgrade in Armageddon: The Return of Yarrick

If your ideal Astra Militarum army involves roaring engines, rolling steel, and enough tracked armour to shake the table, the latest Armageddon update is very much for you.

Games Workshop has revealed two new Detachments for the Astra Militarum in Armageddon: The Return of Yarrick, and both of them lean hard into one of the faction’s biggest strengths: overwhelming force delivered by machines the size of small buildings. One Detachment rewards fast, disciplined mechanised assaults. The other invites you to drive a super-heavy tank straight through the front line and ask questions later.

In short: the motor pool is open for business.

Armoured Infantry makes mechanised Guard look sharper than ever

The first Detachment, Armoured Infantry, is built around classic Guard doctrine: get infantry into transports, get them where they need to be fast, and hit the enemy before they can properly react.

What makes this update especially interesting is how it improves coordination between officers and vehicles. Command structures can now extend their influence to SQUADRON units, giving tank-heavy and transport-led lists more flexibility without forcing in the usual support pieces. That alone makes the Detachment feel more fluid and easier to build around.

Then there’s On My Signal, a new tool for lighter armoured units that adds a clever mobility layer. Instead of simply sitting there and taking a charge, these vehicles can reposition when enemy units close in. It adds a reactive, tactical feel that should make the army feel more alive on the tabletop.

The Stratagem support is where this Detachment really starts to sing. Opening Salvo rewards units that leap from transports and immediately open fire, while Combined Fire helps your lighter vehicles soften up targets so the rest of your force can finish the job. Taken together, the Detachment seems designed to make Chimeras, lighter tanks, and supporting infantry work as one integrated battlefield package.

That’s good news for Guard players who want something that feels mobile, disciplined, and just a little bit nasty.

Steel Hammer is for players who believe bigger tanks solve bigger problems

If Armoured Infantry is about speed and coordination, Steel Hammer is about raw impact.

This Detachment turns the spotlight toward Astra Militarum’s heaviest armour, including Titanic vehicles, and it looks unapologetically brutal. The standout rule, Ceaseless Cannonade, removes one of the classic frustrations of giant tanks: getting tied up in close combat and losing access to your best guns. Under this Detachment, those massive war machines can keep blasting away at point-blank range.

That change alone gives super-heavies a much more aggressive identity. Instead of hanging back as expensive fire platforms, they can now operate like true spearhead units, crashing forward and continuing to punish anything reckless enough to get close.

And yes, the update gets even more dramatic from there.

Titanic units can be given the Character keyword, opening the door to commanding your army from the top deck of an enormous war engine. It’s the sort of rule that feels both flavorful and gloriously excessive, which is exactly why it works so well in Warhammer 40,000.

Assault Hatches and Engine of Wrath add pure spectacle

Two of the most memorable reveals in the article are Assault Hatches and Engine of Wrath, and both push Steel Hammer into full cinematic mode.

Assault Hatches allows infantry to disembark from a moving Titanic transport and still charge. That means your huge command tank doesn’t just deliver troops safely; it launches them straight into the fight. It’s a fantastic rule because it changes a giant vehicle from a transport platform into the centrepiece of a full assault.

Then there’s Engine of Wrath, which gives super-heavy tanks a savage melee punch once they’ve already smashed into the enemy lines. It’s exactly the kind of rule that captures the over-the-top joy of Warhammer: when your tank is too big to politely stop, it simply becomes part of the weapon.

The overall message is clear. These aren’t Detachments that want to wait around. They want to advance, collide, and dominate space.

Why this update matters

What makes these rules exciting isn’t just that they’re powerful on paper. It’s that they give Astra Militarum players two very distinct armoured identities.

• Armoured Infantry supports a more tactical mechanised force, where transports, officers, and lighter vehicles combine to create pressure all over the board.

• Steel Hammer delivers the fantasy of an unstoppable armoured fist, built around massive tanks and close-range destruction.

That kind of separation is healthy for the faction. It gives players clearer choices in how they want their Guard army to feel, not just how they want it to perform.

And from a hobby perspective, it’s hard not to love an update that makes everything from Chimeras to super-heavies feel more relevant. If you’ve been building toward a vehicle-heavy Astra Militarum collection, this looks like one of the most appealing rule updates in a while.

Final thoughts

This reveal feels like a smart and entertaining step for the Astra Militarum. It gives mechanised lists more personality, gives super-heavies more presence, and leans into the kind of battlefield storytelling that makes the faction so appealing in the first place.

Whether you prefer disciplined infantry rolling forward behind armour or a giant tank-led assault that looks like it belongs in the closing act of a war film, these new Detachments seem ready to deliver.

For Guard players, the message is simple: fuel the engines, load the troops, and point the whole convoy at the enemy.
