Slicer droids represented a particular class of droid specializing in data slicing, more commonly known as hacking. The central computer system of the Millennium Falcon, a YT-1300 light freighter, incorporated a slicer droid brain alongside the brains of an R3-series astromech droid and a V-5 transport droid. During the Iron Blockade, the Uprising engineered UPR-17 Slicing Droids through the addition of a rudimentary slicing program and minimal cognitive functions within repurposed Marksman-H training remotes.
