Elevate your Astra Militarum to new heights with the Bridgehead Strike Detachment rules and use focused firepower for maximum impact.

Centered on elite Astra Militarum units like Militarum Tempestus and Kasrkin, this detachment excels at coordinated deployment, focused firepower, and controlling critical objectives. It rewards aggressive playstyles that rely on timing, precision, and adaptability. Here’s how to leverage the new Astra Militarum rules effectively.

If you ever wanted to play a Scion troop or Elysian Drop company, now is your chance with these rules in Grotmas Calendar for December! You can download the full rules here.

Accuracy Meets Lethality

A picture of the Bridgehead detachments' core rule

  • Only the Best: Infantry models re-roll Hit rolls of 1 for ranged attacks, ensuring consistent accuracy across units.
  • Fire Zone Purge: Militarum Tempestus models add +1 to Wound rolls the turn they disembark from a Transport or arrive from Reserves, making them devastatingly effective on the turn they strike.

These rules elevate Militarum Tempestus and Kasrkin into some of the most reliable and deadly units in the Astra Militarum. By combining Fire Zone Purge with Deep Strike or Valkyrie deployment, your units can erase high-value targets with ease.

A fun combination is deploying a Valkyrie full of Scions, landing them next to a crucial target, and watching them melt enemies with boosted Wound rolls and precision hot-shot weaponry. It’s a rule set that rewards bold, aggressive plays and makes every attack count.

Enhancements – Amplifying Officer Impact

  • Bombast-Class Vox-Array (25 pts): Orders can target up to three units simultaneously via master vox, maximizing command efficiency.
  • Priority-Drop Beacon (30 pts): Guarantees Deep Strike for the bearer’s unit in the first three turns, regardless of mission rules.
  • Shroud Projector (15 pts): Prevents Overwatch against the bearer’s unit, ensuring safe deployment into enemy fire lanes.
  • Advance Augury (15 pts): Redeploy up to three Regiment units after deployment, adding flexibility and counterplay to setup.

The Enhancements in this detachment are all about control and precision, giving you tools to shape the battlefield to your advantage. For example, using Priority-Drop Beacon to Deep Strike Kasrkin behind enemy lines while your Scions deploy forward can create a brutal pincer attack.

Meanwhile, Bombast-Class Vox-Array lets your officer issue Orders across multiple units, keeping your strike force cohesive and lethal. These upgrades are versatile, helping you optimize positioning, shut down enemy threats, and coordinate devastating attacks.

Stratagems – Tools for Precision and Mobility

  • Bellicosa Drop (1 CP): Deep Strike a unit within 6″ of enemy models, denying charges that turn.
  • Firing Hot (1 CP): Boosts the Strength and AP of hot-shot weapons by 1, enabling Scions and Kasrkin to shred armor and heavy infantry.
  • Fire and Relocate (1 CP): Allows a unit to shoot after Advancing, maintaining firepower while repositioning.
  • Servo-Designators (1 CP): Removes Cover benefits for an enemy unit hit by your Infantry, amplifying the damage of subsequent attacks.
  • Aerial Extraction (1 CP): Pull a Valkyrie or Deep Strike unit off the board and into Strategic Reserves, preserving key assets for later turns.
  • On My Position (2 CP): Inflict D6 mortal wounds on enemies within Engagement Range but sacrifice your unit in the process.

The Stratagems in Bridgehead Strike are packed with tactical flexibility, allowing you to adapt to any situation. Pairing Bellicosa Drop with Fire Zone Purge turns your Deep Striking Scions into a lethal precision force, while Servo-Designators ensures follow-up firepower from other units is even deadlier.

For extra flair, use Aerial Extraction to pull Valkyries or Scions out of danger after they’ve completed their mission, setting them up for another strike. With tools for mobility, firepower, and even sacrificial plays like On My Position, these Stratagems keep your opponent on the back foot.

Army List Themes and Synergies

  • Tempestus Scions Drop Force: Combine Fire Zone Purge and Bellicosa Drop for lethal alpha strikes, enhanced by Firing Hot to shred vehicles or elite infantry.
  • Kasrkin Objective Holders: Use Advance Augury to redeploy Kasrkin into strong positions, bolstered by Orders from Bombast-Class Vox-Array.
  • Valkyrie Strike Teams: Pair Aerial Extraction with Priority-Drop Beacon for consistent redeployment, keeping your units dynamic and hard to pin down.
  • Combined Arms Approach: Exploit Servo-Designators to strip Cover, allowing Kasrkin or Scions to deal maximum damage, while On My Position provides a high-risk, high-reward trade.

This new Astra Militarum detachment is a playground for players who love synergistic combos and creative tactics. For instance, deploying Scions with Bellicosa Drop, following up with Firing Hot, and then using Aerial Extraction to reposition them can cripple key enemy targets while keeping your units safe.

Meanwhile, Kasrkin with Servo-Designators can strip away enemy Cover, letting other units clean up with ease. These builds emphasize flexibility and reward precise planning, making every game a dynamic and engaging experience.
