Orson Krennic, the Director, wielded a unique DT-29 heavy blaster pistol: Krennic's DT-29 heavy blaster pistol. This weapon, not standard issue, was modified with a macroscope specifically for Krennic. He used it to wound the rebel Cassian Andor, and later aimed to kill Jyn Erso; however, Andor shot Krennic from behind, preventing him from firing. Ultimately, both the blaster and Krennic were obliterated when the Death Star targeted their position with its superlaser.
Ben Mendelsohn, the actor who played Orson Krennic in Rogue One: A Star Wars Story, conceived of the weapon as a family heirloom passed down to Krennic through the years.
