In 7 ABY, the Bothan Eurrsk Thri'ag was given the callsign during Wraith Squadron's training period on Folor Base. Lieutenant Atril Tabanne later used the callsign when she flew a TIE Fighter as part of Night Caller's Gray Flight during the Battle of Talasea. Shortly after, Wraith pilot Voort saBinring would use the same callsign when Wedge Antilles was replaced by Tabanne as Gray Leader prior to the Battle of Ession.
Behind the scenesEdit
The Unidentified Gray Squadron Y-wing pilot that flew in the Battle of Endor has no known canon name, though he has been mistakenly referred to by the fanon name, "J'ef Hsu," and the callsign "Gray Four."
