Legion Breacher Siege Squad

A Legion Breacher Siege was a specialised formation of the ancient Space Marine Legions used during the Great Crusade and Horus Heresy eras in the late 30th and early 31st Millennia. Breacher squads utilised specialised cutoms and tactics for the explicit purpose of acting as a vanguard force in the worst conditions imaginable and in the direst of war zones, known as "Zones Mortalis."

History
The most harzardous and desperate spheres of warfare such as boarding actions amid the cold void of space and the forlorn hope of the first wave of attackers into a breached fortress domain often proved lethal beyond endurance, even for the warriors of the Legiones Astartes. For this reason since the early days of the Great Crusade, specialised forms of wargear and tactics had been under continuous development to cope with these "Zones Mortalis" and certain Legions such as the Imperial Fists, World Eaters and the Iron Warriors had even made these bloody modes of warfare their particular concern. Breacher Siege squads were units of Space Marines equipped with specialised arms and armour, employing specially customised and augmented suits of hardened Power Armour (usually variants on the Mk III "Iron" pattern) modified by the Legion's Techmarines to better withstand the rigours of siege warfare, lethal environments and close-quarter boarding actions in space. Breacher Siege squads often employed heavy ablative shields to resist enemy fire and specialised breaching charges and lascutters to bypass bulkheads and shatter strongpoints. The servos and power systems of such armour were overstrained as a result of these modifications, and required constant extensive maintenance between battles. This deficiency was one of the mitigating factors that ultimately led to the Tactical Dreadnought Armour project.
