BN-749 was the designation of a male stormtrooper who served the Galactic Empire's Stormtrooper Corps on the planet Lothal. He was stationed on the Sentinel-class landing craft Lagos which was used to transport droid couriers to communications ships in orbit while all long-distance communication on the planet was disabled. When a group of rebels replaced one of the couriers with their own droid C1-10P, BN-749 ignored the rebel droid's lack of an escort and allowed it onboard the Lagos. The shuttle then traveled to an Arquitens-class command cruiser in orbit, where C1-10P successfully discovered the location of the Imperial prisoner Kanan Jarrus and escaped.
