It’s kind of debatable though. Even as it swings around right after the “they’re going after the medical frigate” line it’s not clear which guns are firing.
Is it though?
Those clearly do not come from the turrets. Funnily the Falcon fires only 3 times but the sound effect comes 6 times.
I’ve always thought that it had front lasers, for a guy like Han Solo it would feel really stupid if he only had the turrets. He even has hidden cannons to shoot people.
