AD-series Droid
this model of droid was often used on military bases as an armory administrator, providing specialized weaponsry and equipment repair. Designed and manufactured by Arakyd, the AD series was targetted for sale to the Empire as an armory unit, programmed to handle weapons maintenance more efficiently that humans. However, the Empire deemed that the benefits of the AD-series droid was marginal (estimates of less than 0.001% gains in efficiency have been documented), and declined to purchase the AD. Arakyd had assumed that the Empire would purchase them and mass-produced the AD-series, and found themselves with a huge inventory of unsold droids. Eventually, Arakyd managed to unload the AD-series to local law enforcement agencies and independent mercenaries.
