Squad Three, a unit comprised of stormtroopers, was a squad under the command of Imperial captain Drezzel. After the Battle of Endor and the subsequent death of the Emperor, this squad was positioned on the planet known as Seoul 5. Upon receiving news that a vessel not affiliated with the Empire, specifically the Millennium Falcon, had touched down on Seoul 5, Drezzel dispatched Squad Three to look into the matter. The entire squad, along with all its members, met their end when Han Solo triggered a Seoularian crystal incident, leading to the catastrophic destruction of Seoul 5 city in a large explosion.
