When the Legiones Astartes are called upon to take a heavily defended, yet confined position, they send in a Siege Assault Battle Group. Composed of a mix of Cataphractii Terminators and Breacher Squads, and supported by a Leviathan Siege Dreadnought, they march confidently through heavy enemy fire and mercilessly cut down their foes.

If you want to claim the galaxy in the name of the Emperor (or tear it all down in the name of Horus), this box is the perfect way to start a new Legiones Astartes collection – or expand an existing army – and save money compared to buying the kits individually. Based around a core of versatile Cataphractii Terminators, virtually impervious to small arms fire and equipped with deadly weapons, and a unit of Breachers – shield-bearing first-wave assault specialists. Supporting the infantry is a hulking Leviathan Siege Dreadnought capable of making short work of everything from fortifications to enemy armour. It's the first place you'll be able to get your hands on the new MKIII Breacher Squad and Cataphractii Terminators miniatures.

This box contains 23 multipart plastic miniatures:
– 1x Leviathan Siege Dreadnought
– 10x MKIII Breacher Squad miniatures
– 6x Cataphractii Terminators with volkite chargers and power mauls
– 6x Cataphractii Terminators with combi-bolters and power fists

The miniatures in this kit are easy to customise. The Dreadnought's torso houses a pair of auxiliary weapons – your choice of heavy flamers or twin-linked volkite calivers – and it can also be armed with an optional hull-mounted phosphex discharger. Each of the Leviathan's mechanical fists is armed with a built-in meltagun and can be assembled as either a crushing siege claw or a grinding siege drill, with individually posable digits. The kit also includes a choice of different armour plates.

One of the Breachers can be built as an optional Breacher Sergeant with a choice of two heads – helmeted or bare – and an optional breacher charge. There are parts to optionally equip one squad member with a lascutter, one with a graviton gun, one with a nuncio-vox, and another with a vexilla.

Each unit of Cataphractii Terminators can build an optional Cataphractii Terminator Sergeant, armed with a power sword, power axe, or thunder hammer. Each Terminator has a choice of two types of shoulder pads and matching tasset plates, and an optional tilting plate. One combi-bolter armed miniature can be upgraded with a heavy flamer, one power fist can be upgraded to a chainfist, and one volkite charger can be replaced with a reaper autocannon.

This kit is supplied with 3x Legion Infantry Transfer Sheets, each containing 618 high-quality waterslide transfers, and 1x Legiones Astartes Dreadnought Transfer Sheet, containing 528 high-quality waterslide transfers. These include symbols for the Iron Warriors, Sons of Horus, Salamanders, and Imperial Fists, along with numerals, honour markings, generic markings, script, and command icons.

This kit comprises 745 plastic components, 12x Citadel 40mm Round Bases, 10x Citadel 32mm Round Bases, and 1x Citadel 80mm Round Base. These miniatures require assembly and are supplied unpainted

The Breacher Squad Upgrade Frame and Cataphractii Terminators will be available separately at a later date. The Leviathan Siege Dreadnought is available separately. This boxed set is only available while stocks last.
