The Armature-class Assault Droid was a new model that was designated as the first of the next wave of droids manufactured by Cylon Cybernetics. The initial design began shortly after the Battle of Taylon involving the Cylon Imperium, and the first prototypes were ready for testing shortly after the Sith-Cylon War. Darth Trayus decided to field-test the droids during his attack on Taylon; a test that would prove the droid design ready for combat.
