Built to approach its targets silently and with utmost stealth, the Kharon Pattern Acquisitor is deliberately made to be a thing of mystery and terror when its presence is unveiled. Used primarily in a paramilitary role by the Sisters of Silence, it can suppress civilian resistance with lethal effect, its hellion cannon cutting through rampaging mobs and destroying makeshift barricades. Against greater threats, various payloads of missiles can be deployed, including sophisticated antipsyker warheads.
This is one of the strangest Imperial vehicles from Games Workshop. Almost too futuristic for the Warhammer 40000 Imperium, it would appear that in the Horus Heresy there was a much higher level of technology that was utilised by different forces.
