Anvil Siege Force

Anvil Siege Force seems to be the Detachment of choice for the stoic defenders… (looking at you Imperial Fists players). So if your playstyle is built around planting your feet and holding your ground – well this is the Detachment for you!

It benefits greatly players who like to be immobile and provides great bonuses if you manage to keep your distance from your opponent. Emphasis here is on IF as chances are, if you’re playing top-level, experienced players will figure out a way to get around that.

Here’s what Anvil Siege Force brings to the table:

Architect of War (+25 Points): gives a unit the ability to ignore Cover

Firestorm Assault Force

This Detachment is build around close ranged weapons such as flamers, fast moving vehicles and transports and trying to get as close to your opponent as fast as possible. It’s the literal opposite of the Anvil Siege Force Detachment.

The Firestorm Assault Force is immensely potent, and at the time of writing, among the top contenders for the most formidable detachment in the new Adeptus Astartes Codex.

Also, it’s worth mentioning that out of the 6 stratagems presented, 5 are categorized as Battle Tactics – the Stratagems you are able to use together with the “0 CP” abilities and with the “vect – increase cost by 1” abilities.

The Sons of Sanguinius Space Marines Detachment can incorporate units with the BLOOD ANGELS keyword and units with ADEPTUS ASTARTES keyword. Models containing other Chapters’ keyword are excluded.

This new addition offers a unique blend of Enhancements and Stratagems tailored to the Blood Angels’ aggressive style of combat.

While they remain Space Marines at heart, the Blood Angels now boast a distinctive Detachment ability, “The Red Thirst,” amplifying their melee prowess. This ability, a nod to their Chapter trait from previous editions, grants units an extra punch in melee combat after charging.

Furthermore, the Sons of Sanguinius Detachment introduces a set of Enhancements, with standouts like the “Visage of Death” and “Icon of the Angel” that can significantly influence battlefield dynamics.

Perfect if you favor favors fast, aggressive play with tactics such as Charging your opponent and building your strategy around key Characters such as Lemartes, Mephiston and of course, Commander Dante.

On the Stratagem front, options like “Angel’s Sacrifice” and “Red Rampage” offer strategic depth, allowing players to adapt and respond to various in-game situations.

However, the real essence of this update lies in the balance it strikes. While the Detachment offers compelling advantages, players might find themselves torn between the Sons of Sanguinius and the Gladius Task Force, each offering its unique perks.

Black Templars’ Righteous Crusaders Detachment

If you’re a fan of the super-zealous, super-space-soldiers that are the Black Templars then, you’re in luck as the 10th Edition of W40k comes with a Detachment just for them.

Built around the Templars’ vows (and their hate for Psykers), the Righteous Crusaders Detachment is a great choice for players who like to field a lot of melee-focused army, with lots of infantry units and some great Transports to help you get right into your opponent’s face!

Based on a very early impression, this Space Marines Detachment seems like a great choice for players who like to have an answer to any opponent – regardless of them fielding a tanky, horde or psyker-heavy army. Moreover, certain Strats in this detachment get a boost if certain Vows are active.

The stratagems, all priced at 1 CP, are meticulously designed for your crusading spirit. “Unbreakable Lines” fortifies your defenses, while “Intractable” ensures your Templars never falter in their advance. And for those moments of divine wrath? “Grim Retribution” and “Unforgiven Fury” are at your beck and call.

Your unit can move up to D6” closer to the unit that targeted them, or a straight 6” towards that unit or a Psyker if Abhor the Witch, Destroy the Witch vow is in effect.

Dark Angels’ Unforgiven Task Force Detachment

With the return of the Lion, the Dark Angels seemed to be among the Space Marines chapters of the 10th edition. Looking at their Detachment – and analyzing the initial feedback from the community it seems the Dark Angels initially struggled in the edition, with a win rate in the low 40s, taking some time to establish themselves.

Nevertheless, in the most recent Metawatch update, DA players climbed to a 48% win rate as of 17th October 2023, and it seems that the faction just needed some time to identify a build that truly suits them.

As a Dark Angels player, the 10th Edition offers you a renewed sense of strategy with the “Unforgiven Task Force” detachment. You’ll find the “Grim Resolve” rule a game-changer, setting your Dark Angels apart and giving them a unique edge on the battlefield.

No longer will you worry about conventional morale dynamics. With “Grim Resolve”, your units showcase their unwavering determination, ensuring you maintain a strong presence on objectives.

The stratagems, each at 1 CP, are tailored for your tactical needs. With “Unbreakable Lines”, you can bolster your defenses, while “Intractable” ensures your forces remain relentless. The “Grim Retribution” and “Unforgiven Fury” stratagems are perfect for those moments when you seek vengeance against foes.

For customization, the new enhancements are a treat. Equip your champions with the “Shroud of Heroes” for that dramatic last stand or the “Heavenfall Blade” to cut through enemy lines.

However, be mindful of the detachment’s nuances. It’s crafted specifically for the Dark Angels, ensuring your army remains pure and true to its lore. This might limit some of your unit choices, but it also reinforces the unique identity of the Dark Angels, making your games even more thematic.

True to lore, Dark Angels maintain their ground, even when rattled by the tide of combat.

Deathwatch’s Black Spear Task Force Detachment

Deathwatch players, rejoice! The 10th Edition of Warhammer 40,000 brought forth a Detachment just for you! The faction some of the most formidable capabilities and stratagems among the Space Marines Detachments, positioning them as strong candidates for one of the best Space Marines faction to bring to the tabletop.

The 10th Edition introduces a refined tactical layer for the Deathwatch through the “Black Spear Task Force” detachment. At its core is the unique “Kill Teams” rule, setting the Deathwatch apart from traditional Space Marine chapters.

Instead of standard unit dynamics, Kill Teams adapt to the battlefield, using the majority toughness value for wound determination and showcasing flexibility in transport capacity, treating all as Infantry.

The detachment’s “Mission Tactics” is a game-changer. Players can now adapt to various battlefield scenarios, from “Furor Tactics” for widespread destruction to “Purgatus Tactics” for precision strikes on enemy leaders, emphasizing the Deathwatch’s role as specialized xenos hunters.

Stratagems have been fine-tuned, each at 1 CP, and are tailored to synergize with active Mission Tactics. “Adaptive Tactics” allows for tactical shifts, while “Teleportarium” offers strategic redeployment. Specialized ammunition types, like “Hellfire Rounds” and “Kraken Rounds,” further emphasize the Deathwatch’s adaptability against various xenos threats.

Enhancements, reminiscent of the previous edition’s relics, provide additional customization. Standouts include “Dragonfire Rounds”, granting the ASSAULT and IGNORES COVER abilities, and “Hellfire Rounds”, enhancing anti-infantry capabilities.

However, there are constraints. The detachment is exclusive to Deathwatch units, barring other Adeptus Astartes chapters. Also, staple units like the Tactical Squad and Assault Squad are conspicuously missing.

Deathwatch Army Rule

To further highlight their awesomeness in the Warhammer 40k universe, the Deathwatch is one of the few factions that gets its own army rule called Kill Teams (they still can access Oath of Moment, which is available for all Space Marines armies).

The Kill Teams Army Rule provides three simple changes to traditional rules:

When an attack targets a Kill Team unit in your army with varying Toughness characteristics, use the Toughness of the majority of models for wound determination until the attacker completes its attacks. If there’s a tie in Toughness, use the highest value.
Regarding Transport capacity, Kill Team Terminator, Outrider, Biker, and models with jump packs occupy the space of 2 models. However, they can board any Transport their unit can, even if similar models in other units have Terminator, Mounted, or Jump Pack keywords.
For terrain interactions, all models in units with the Kill Team ability are considered Infantry, regardless of their similarities to models in other units.

Black Spear Task Force Detachment Rule

At the beginning of your Command phase, choose one of the listed Mission Tactics. Its effects apply to all your units with this ability until your next Command phase. Each Mission Tactic can be chosen only once in a battle.

Malleus Tactics: Focused on targeting the weak points of large foes, the Deathwatch uses this tactic against massive enemies. While active, Adeptus Astartes units’ weapons gain the LETHAL HITS ability.
Purgatus Tactics: The Deathwatch zeroes in on enemy leaders, aiming for precise eliminations. When active, if an Adeptus Astartes unit scores a Critical Hit, that attack gains the PRECISION ability.

Space Wolves’ Champions of Russ Detachment

Renowned for their fierce autonomy, deep brotherhood, and unmatched hand-to-hand combat skills, the Space Wolves of the Warhammer 40k universe require a tactical approach that combines raw ferocity with astute pack dynamics.

And, in the 10th edition of W40k, the Sons of Russ got a Detachment to match.

The 10th Edition brings a fresh tactical depth to the Space Wolves with the introduction of the “Champions of Russ” detachment. Central to this is the innovative Sagas system. Instead of traditional Warlord traits, Sagas activate army-wide benefits upon achieving specific battle milestones.

For instance, completing the “Saga of the Warrior Born” empowers all melee weapons with the “SUSTAINED HITS 1” ability, while the “Saga of the Bear” grants a “Feel No Pain 6+” ability, emphasizing the importance of character actions on the battlefield.

Stratagems have been revamped, each costing 1 CP, and are designed to synergize with completed Sagas. “Runic Wards” offers protection against mortal wounds, with its effects enhanced by the “Saga of the Bear”. Similarly, “Go for the Throat” boosts melee weapon armor penetration, with added benefits if the “Saga of the Beastslayer” is active.

Enhancements, akin to relics from the previous edition, allow players to customize their characters further. Notable ones include “Frost Weapon”, enhancing melee prowess, and “The Pelt of Balewolf”, forcing enemy Battle-shock tests.

However, these benefits come with restrictions. Players are limited to Space Wolves units, excluding other Adeptus Astartes chapters. Additionally, certain units like the Tactical Squad and Assault Squad are notably absent from this Space Marines detachment.

Champions of Russ Detachment Rule

After a battle round, choose one of the Sagas below; if completed, all Adeptus Astartes models gain its benefit for the battle, but each Saga can be chosen only once.

Saga of the Warrior Born: If an Adeptus Astartes Character from your army eliminates an enemy Character during the battle round, your army’s melee weapons gain the SUSTAINED HITS 1 ability.
Saga of the Bear: If an Adeptus Astartes Character from your army drops below half their starting wounds but survives the battle round, your army’s models gain the Feel No Pain 6+ ability.
Saga of the Beastslayer: If an Adeptus Astartes Character from your army destroys an enemy Monster or Vehicle during the battle round, your army’s melee weapons gain the LETHAL HITS ability.
Saga of Majesty: If an Adeptus Astartes Character is within range of an objective in the opponent’s deployment zone at the end of any turn during the battle round, your army’s models increase their Objective Control characteristic by 1.

If the Saga of the Bear is completed, this improves to a FEEL NO PAIN 4+ ability.

If the Saga of Majesty is active, nearby enemy units within 6″ must also undergo a Battle-shock test.
