All throughout the Horus Heresy, the Space Marine Legions were required to attack and take down enemy fortifications, frequently built and maintained by their former brothers in arms. The Siege Assault Battle Group brings together 23 miniatures that excel in cracking fortresses and bunkers, and fighting in the remaining rubble.

This is the first time you can get hold of the new Cataphractii Terminators, which are delivered in two sets of six. These heavily armoured suits of Tactical Dreadnought Armour, equipped with extra shield generators, make their Space Marine wearers slow but nigh-on unstoppable as they advance. One set of six are armed with volkite chargers and power mauls, with options for a Cataphractii Terminator Sergeant – power sword, power axe, thunder hammer, multiple crest options or grenade harness – while one Terminator can be armed with a reaper autocannon. The other set of six are armed with combi-bolters and power fists, with the same options as above to mark out your Sergeant, and the choice to equip one miniature with a chainfist, and one with a heavy flamer.

The box also contains 10 Breacher Squad Space Marines, made by combining 10 MkIII Legionaries with a brand new Breacher Squad upgrade frame, which contains the following options:

10 boarding shields
10 helmeted heads
Two Breacher Sergeant heads (one helmeted, one bare)
One breacher charge
One lascutter
One graviton gun
10 bolters
10 left arms
10 right arms
10 left hands (boarding shield attachment)

A mighty Leviathan Siege Dreadnought rounds things out, armed with a brutal siege claw and siege drill, which will make short work of even the toughest fortifications and mobile armour, let alone any poor Space Marines who get in the way. This box also contains three Legion infantry transfer sheets containing 618 decals each, and a Legiones Astartes Dreadnought transfer sheet with 528 decals. The box is available while stocks last
