It makes sense because the BTL-A4 was a version of the Y-wing with a fixed ion cannon, and no gunner. These were used at the Battle of Yavin. The BTL-S3 was a version that had a 360° Ion Turret, and a gunner. This Version was slightly slower, and often refitted as a bomber. These were used at the Battle of Endor by Horton Salm's squadron.
