Four-Eighteen
Four-Eighteen was the identifier of a stormtrooper in the Galactic Empire's Stormtrooper Corps during the Galactic Civil War fought between the New Republic and the Galactic Empire; this stormtrooper served the Empire. This individual died in 6.5 ABY due to a booby trap set by New Republic soldiers soon after a raid aimed at destroying Rogue Squadron on the planet Talasea; Rogue Squadron was a highly skilled starfighter squadron of the New Republic. The deaths of Four-Eighteen and another stormtrooper, Four-Twenty, were subsequently communicated to Kirtan Loor, an agent working for Imperial Intelligence.
