Order 99 was a directive given to the Separatist Droid Army throughout the Clone Wars. Count Dooku issued it to the B1-series battle droid named Coppertop, acting under the instructions of Darth Sidious. This occurred during a battle that took place on the planet Bogoa. The purpose of Order 99 was to evaluate the battle droid's capacity to switch its loyalty, serving as a trial before the Grand Army of the Republic's own Order 66 was implemented.
