SD-9 battle droids.

The SD-series was a battle droid series produced by Balmorran Arms.


The droids were used by the Galactic Republic and the Galactic Empire. Most of the SD-1 to 9 series were subsidized by the Galactic Empire due to the aftermath of the Clone Wars.

They gained notoriety during the Battle of Balmorra after the second death of the reborn Emperor Palpatine. Amidst the chaos of the Galactic Civil War, the Balmorrans were able to secretly design the superior SD-10 series and the X-1 Viper which outmatched the empires SD-9 battle droids and their shadow droids, bringing the battle to a draw. The reason the SD-10's were superior to the SD-9's was due to them being programmed with the latter's tactics.

The SD-series battle droids were later supplemented with the LON-29 battle droid commander model, intended to be a more tactical unit devoted to leading and guiding the actions of the other battle droids on the battlefield.
