A specialized group within the First Order Navy was operational throughout the conflict against the Resistance. This group was organized around the First Order's primary command ship and center of power, the Supremacy. In the Battle of Oetchi, Vice Admiral Amilyn Holdo of the Resistance executed a hyperspace jump with the Raddus, directly through the specialized group. This group was made up of the Supremacy, a Mega-class Star Dreadnought, along with thirty Resurgent-class Star Destroyers, among which were the Conqueror, the _Harbinger_, and the Finalizer.
