What is the name of the Rebel squadron Luke flies with during the Death Star trench run?

During the Battle of Yavin, Luke’s callsign is Red Five, placing him in the X-wing attack unit led by Garven Dreis (Red Leader) that conducts the trench run. The other options point to different units or battles: Rogue Squadron is formed later and becomes prominent by The Empire Strikes Back; Blue Squadron appears in Rogue One’s Scarif assault (the name was avoided in 1977 due to bluescreen effects); Green Squadron is the A-wing group at Endor in Return of the Jedi. Context: This unit included pilots like Wedge Antilles and Biggs Darklighter, flying T-65B X-wings. Their coordinated torpedo runs—and Han Solo’s last-minute intervention—enabled Luke to destroy the Death Star, delivering the Rebellion its first major victory.
