An attack droid represented a type of war droid utilized as a tool of war by the Galactic Empire. These attack droids were equipped with weaponry consisting of a blaster rifle that could pivot a full 360 degrees, along with a medium repeating blaster, and a grenade launcher which held a magazine of five concussion grenades. A number of these attack droids were stationed on the Victory-class Star Destroyer known as the Dominator, and they were involved in the Battle of Taul.
Certain Viper probe droids, for example AD-43, also performed the role of attack droids.
