An ambitious, ruthless proponent of military power, Tarkin became a favorite of Supreme Chancellor Palpatine and rose rapidly through the Imperial ranks. Shortly after the Empire's creation, he was put in charge of the construction of the Death Star. Tarkin saw the Death Star as a way to crush all dissent to the Empire's rule -- fear of the station's planet-killing superlaser would keep the galaxy's star systems in line.

Rather than use flesh-and-blood warriors, the Separatists prefer mindlessly loyal soldiers that are easily controlled. The soulless ranks of their armies are dominated by tall, thin B1 battle droids built as mechanical imitations of their Geonosian designers. Battle droids can be controlled by centralized command centers such as the Trade Federation’s enormous Droid Control Ships, or programmed for independent action. They often suffer programming glitches that manifest as personality quirks. Battle droids are dim-witted and no match for clone troopers or Jedi, but they weren’t designed to be smart – they were designed to overwhelm Republic civilians through sheer numbers, something they do very effectively.
