Green Twelve was the designation given as a callsign to the pilot who flew as the twelfth member of the Green Squadron. During the period surrounding the Battle of Scarif, this callsign was actively used by lieutenant Wion Dillems after Puck Naeco no longer occupied that position.
The callsign Green Twelve initially appeared within the 2015 video game Star Wars Battlefront, which was brought to the public by Electronic Arts.
