An attack droid was a class of war droid employed by the Galactic Empire. An attack droid was armed with a blaster rifle capable of rotating 360 degrees, a medium repeating blaster, and a grenade launcher with a magazine of five concussion grenades. Several attack droids were assigned to the Victory-class Star Destroyer Dominator, and participated in the Battle of Taul.
Some Viper probe droids like AD-43 had the function of attack droids.
