Sith droid

Sith droids were a class of advanced battle droid developed by Sith Intelligence during the latter years of Darth Abeonis' reign. Originally built to replace Sith troopers based on some of the Empire's more inhospitable planets, the class was found to excel in all areas, and were soon being used not only as planetary garrisons; but as front line support troops and even assassin droids.

One of only a few classes of droids the Sith used throughout the empires' existence, they were used a lot during the Successors War due to their limited-Force resistant armor. They were used in excess during the attack on the Conclave on the Sluis Van Shipyards, with devastating efficiency.
