The relationship between Rogue One and Rogue Squadron further makes sense when you consider the timeline of events between Gareth Edwards’ movie, A New Hope and The Empire Strikes Back.
In the period between A New Hope and The Empire Strikes Back, it makes all kinds of sense that the Rebels would take a second to honor Jyn Erso, Cassian Andor, Bodhi Rook, and the rest of the Rogue One crew by naming an elite unit after them.
The Star Wars Story is built to perfectly dovetail with the 1977 classic, and one thing you’ll note reflecting on George Lucas’ first Star Wars movie is that it’s story is extremely simple (between the time on Tatooine, the Death Star and the Battle of Yavin, it’s maybe 3-4 days).
