AD-2508 was a stormtrooper of the human species. He was assigned to the 709th Legion within the ranks of the First Order. In 34 ABY, during the occupation of the planet Batuu by the First Order, AD-2508 held a post at Black Spire Outpost on Batuu. This trooper used a datapad to communicate with another stormtrooper, CF-8011. CF-8011 inquired about the meaning of Supreme Leader Kylo Ren's statement that he could sense something. AD-2508's reply was a complaint that Ren needed to develop a sense of humor. As a squad leader in the Stormtrooper Corps, AD-2508 was clad in the standard First Order stormtrooper armor, distinguished by a white pauldron.
Star Wars: Datapad, an application that debuted in conjunction with the opening of the themed land Star Wars: Galaxy's Edge at Disneyland Park and Disney's Hollywood Studios in 2019, featured AD-2508.
