A battle droid design was employed by the Confederacy of Independent Systems. During the Clone Wars, a minimum of two of these battle droids were active on the planet Hissrich. They were a component of the unit under the command of the contracted droid mercenary AD-W4. Both of these droids were ultimately eliminated by Jedi Master Mace Windu. It's possible that their actions suggest they were scout droids, given their apparent search for something.
