The Siege Breakers are a small mercenary unit of elite ex-Confederate siege tank pilots. They claim they can solve all one's problems with one shot of their vehicles with mounted customized and "overcharged" cannons^[1]

The Siege Breakers were active in 2504, offering their services to Raynor's Raiders after the Raiders made off with another artifact component from Xil^[1]. They also accompanied the Raiders during Sarah Kerrigan's invasion of Korhal.^[2] There were also members in the Umojan Protectorate^[3] and Mira's Mercs.^[4]

DevelopmentEdit

Caution was applied when designing the Siege Breakers due to experience from developing the siege tanks originally, with the heavy fan backlash that was involved. However, the customizations were quite extensive, and nearly warranted remodeling the siege tank completely. All six transforming plates, the gun barrels, and the turret plates were brand new custom pieces of art based off a preliminary siege tank concept from Blizzard's cinematic department.. The plates were quite bulky and had many different interesting levels which caught the light. Unlike the siege tank, which was designed to be "gritty," the Siege Breaker vehicles "embraced" color.^[8]
