SD-series battle droid/Legends

The SD Battle Droid Series were of Balmorran lineage. Mainly used during the Battle of Balmorra after the second death of the Clone Emperor. Most of the SD-1 to 9 series were subsidized by the Empire due to the aftermath of the Clone Wars. However, amidst the chaos of the Galactic Civil Warr the Balmorrans were able to secretly design the superior SD-10 series and the Viper Automadon.
