A player can gain access to other Houses' special units by capturing an enemy Factory and manufacturing the desired units at the captured Factory (House Atreides' Heavy Vehicle Factory for "Sonic Tank", House Ordos' Light Vehicle Factory for "Raider" trikes, House Ordos' Heavy Vehicle Factory for "Deviator" tanks, or House Harkonnen's Heavy Vehicle Factory for "Devastator" tanks). Note that a "Deviator" not owned by House Ordos still switches control of targeted units to House Ordos, and not to the side that owns the "Deviator". Apparently Westwood was aware of this feature, since capturing a Sardaukar Heavy Vehicle Factory allows the player to build both the "Sonic Tank" and Devastator, but not the Ordos "Deviator".
