Sith Elite Warbot
these combat droids were developed by the ancient Sith to serve as part of their ground-based armies. Individual Elite warbots were used for both training and active combat, with stun blaster and stun batons used on training versions. Full combat versions were armed with a blaster pistol mounted on each arm, and carried a Sith sword as a melee weapon. The armor of the Elite warbot was alchemically treated, giving it additional protection in combat. Unfortunately, they were very expensive to produce, and never found widespread use in the army. Like most other ancient Sith droids, most of the Elite warbots disappeared after the Great Hyperspace War.
