The pods resembled large cubes with platforms and small activation consoles inside. A pod's machinery was vulnerable to sonic waves but could be repaired quickly with a Sontaran baton. Small beacons were also used in the campaign. These resembled discs and could be attached to surfaces, allowing the Sontarans to teleport things onboard their ship. (TV: The Sontaran Stratagem / The Poison Sky) After the invasion was repelled, the pods came into the possession of UNIT. This led to the creation of Project Indigo. (TV: The Stolen Earth)
