Void-tank
Void-tanks were a type of space-faring tank fielded by the Dalek Empire during the Last Great Time War. Much like Dalek mega-saucers, void-tanks were far superior to the ancient Time Lord ships the Gallifreyans had Time Scooped from their past. Void-tanks resembled (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) the spacecraft used by the Imperial faction during the Imperial-Renegade Dalek Civil War (TV: Remembrance of the Daleks) and had a similiar name to "Void Ships", a type of vessel designed to exist outside of space and time in the Void. Whilst the Time Lords thought Void Ships would be impossible to actually create, the Daleks did show the ingenuity to actually create at least one proper Void Ship, the Sphere. (TV: Army of Ghosts)
Several void-tanks were deployed into the fateful battle of Seramiphius V. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)
