MKIII Breacher Squad Upgrade Kit – Warhammer: The Horus Heresy Breacher Squads are deployed into the deadliest warzones of the Age of Darkness — voidship boarding actions, siege assaults, and the brutal first waves of fortress breaches. Since the earliest days of the Great Crusade, their specialised equipment has been refined to withstand punishing enemy fire while delivering devastating close-range attacks. Heavy boarding shields and purpose-built weapons allow Breachers to shatter strongpoints and force their way through bulkheads where standard Legionaries would falter. This multipart plastic upgrade kit converts a MKIII Tactical Squad into a Breacher Squad for your Warhammer: The Horus Heresy Legiones Astartes armies. Designed to add durability and close- to mid-range firepower without sacrificing flexibility, this kit equips your Legionaries for the harshest boarding actions and siege warfare scenarios. ⚠️ Requires MKIII Tactical Squad (sold separately).
