Jarban gliders bodies house terrazine, though by using a biomechanical extraction device the terrazine can be extracted from their bodies. After the End War, an Umojan Protectorate research team sent to Jarban Minor set up these extraction devices and attached Jarban gliders to them to extract terrazine from them. However, the zerg attacked their research base, killing and infesting the majority of the research team, leaving several Jarban gliders still attached to the extraction devices. During the Defenders of Man Insurgency, Agent Nova Terra used these extraction devices to gather terrazine from the gliders, and the Jarban gliders were released from the devices after the harvesting process ended.
