"Three dozen TIE-Fighters destroyed, a Stardestroyer heavy damaged, the target escaped and all this was done by a rookie pilot! How could someone as incompetent as you achieve that rank?" "Mylord, i argh.......!" "You have failed me for the last time, Captain!"
I’m not sure. The game came after the canon reset and everything that was made after that is of course supposed to be the new canon, including games. But there is no story in the main game, and the characters here all just go by their callsigns. But this was technically the first appearance of extraction team bravo, the unit that freed Jyn in the movie. So I think it’s sitting on a line in the middle, assumed canon until proven otherwise. Here’s an interesting ign article www.ign.com/articles/2015/04/29/star-wars-battlefront-canon-is-complicated that tries to clarify if the base game itself is canon with the GM of DICE.
