Sentinel droid

Republic war droids were the only known model of androids among the war machines used by the Galactic Republic and the Sith Empire in the Jedi Civil War. The Sith units were presumably a leftover from the part of the Republic military Darth Revan had assumed control over after the Mandalorian Wars.

Republic war droids were equipped with blaster rifles and could benefit from personal energy shields, which, unlike spheric energy shields utilized by other models, allowed them to move while shielded.

Despite their considerable efficiency, these droids were not very common, as they were not optimized for mass production, unlike the much later Trade Federation B-1 battle droids, and the niche of limited-quantity battle droids had been assumed by Republic assault droids and Sith assault droids. Besides, both the Republic and the Sith preferred to rely primarily on live soldiers.

However, some people, like Ahlan Matale and Nurik Sandral, used these droids as bodyguards.
