Although each house has many common units, such as infantry, Wind Traps, and Mobile Construction Vehicles, each House also has its own set of units, such as the Atreides Sonic Tank, the Ordos Deviator and the Harkonnen Devastator. Houses Harkonnen and Atreides share the Trike, while House Ordos has an upgraded version, the Raider. Like many games of the Westwood franchise, a player can gain access to other Houses' special units by capturing an enemy building that can manufacture the desired units. House Ordos can obtain the Missile Tank by ordering it from the Starport when it would otherwise be inaccessible. After patch 1.06, the Harkonnen can eventually train the Sardaukar, which are soldier-fanatics loyal to the Corrino Emperor.
