The Conqueror was first created on [[Gryphonne IV]] when its plans were rediscovered sometime in the [[M38|38th millennium]]. Now the plans reside with [[Mars]] and several other Forge World Worlds are trying to get an approve approved access to them. Originally, battlefield commanders voiced concerns that the smaller cannon would reduce the available firepower and result in poor battlefield performance. During field testing however it was shown that the reduced recoil of the gun made up for its reduced power with improved accuracy while firing on the move. The smaller shell size also allowed loaders to fire faster and carry more ammunition than the standard Leman Russ Battle Tank.{{Fn|1a}}

The entire first batch of Conquerors produced was assigned to the Gryphonne IV [[Skitarii]] forces for the [[Castra Campaign]], where they operated alongside a battle group of the [[War Griffons]] [[Titans]]. During the campaign the Conquerors proved they could easily keep pace with the Titans as they encircled and trapped the besiegers of [[Hive]] [[Castra Septus]], annihilating the traitors within the pocket{{Fn|1a}} and collapsing the hive in the process.{{Fn|3a}} Following this success production of the Conqueror increased and was exported to the [[Imperial Guard]], where it has become popular among tank crews and unofficially known as a 'breakthrough' tank. Currently only Gryphonne IV produces the Conqueror in significant numbers, though the plans also reside with [[Mars]] where a Mars Alpha pattern is also produced, and a number of other [[Forge World]]s have petitioned for access to the blue-prints.{{Fn|1a}}

At some time during the [[M39|39th millennium]], special munitions were created on Gryphonne IV by the munitions adepts, who were trying to increase the tank's firepower with the use of "Auger" (or '''Augur'''){{Fn|3c}} shells. The warhead of such a shell consist of a soft explosive in a thin shell that is designed to break open on impact, spreading the explosive over the surface of the specific target during the microsecond before the base-mounted fuse detonates it. This is liable to kill or wound any occupants, and can disable instruments and controls, because of breaking off the interior layers of the target and ricochets around inside a vehicle.{{Fn|3c}} However after seeing the limited size of use on a battlefield, this these type of shells was considered a failure by many and production of these shells is no longer permitted.{{Fn|1a}}{{Fn|3c}}
