Sophisticated blasters, which are also referred to as sophisticated lasers, represented a significant upgrade to the blasters found on various starfighters. As their designation implies, these weapons enhanced the destructive capabilities of a spacecraft's laser weaponry.
After saving Tycho Celchu, a TIE pilot who had recently defected from the Imperial forces, on Dantooine and riding speeder bikes to bring him back to the landing area, Luke Skywalker, who was then the commander of Red Squadron, went down the left path when he saw the sophisticated lasers in the vicinity.
While leading Rogue Squadron, Skywalker momentarily broke away from the assault on the last Tibanna gas platform located on Taloraan during a mission intended to destroy Tibanna gas containers owned by the Empire. He executed a rapid descent into Taloraan City close by, securing the sophisticated blasters from the floating city's central plaza, maneuvering carefully between structures to prevent collisions.
During the Battle of Hoth, Wedge Antilles, who was in charge of Rogue Squadron after Skywalker was downed, returned to the now-demolished shield generator at Echo Base to recover the sophisticated blasters from the wreckage.
