TB-278 was the designation of a stormtrooper who served the Galactic Empire. In 0 ABY, TB-278 was among those sent to retrieve a captured Princess Leia Organa on the planet Delaya. Upon the orders of his officer, TB-278 and his squad opened fire and killed J'er Nahj and Halle Dray, the Alderaanians who originally captured Organa. TB-278 and TB-137 were then sent to hunt down Kiro Chen, another captor of Organa that managed to escape.
