- "Fire the Defoliator."
- ―A fellow droid, speaking to this one
This droid along with the rest of the droid army fought the Nightsisters clan on the planet of Dathomir around 21 BBY. During the battle, this droid piloted a Defoliator Deployment Tank, and was ordered to fire it by a fellow droid, taking out a large number of Nightsisters.
Later in the battle, the undead army of the Nightsisters arrived, destroying a large part of the droid squadron and allowing the living Nightsisters, including former Dark Acolyte Asajj Ventress, to hijack an Armored Assault Tank and use it to take out this droid's Defoliator Tank in one shot, killing the pilot.
