There seem to be too much guns for the crew, but not really. Correct me if I'm wrong, but I think you can use Two-weapon fighting here. So the pilot and co-pilot can use one or both of the blaster cannons, and the gunner uses the two more powerful laser cannons. 1. The gunner add one difficulty to its Gunnery check and rolls 2. He spends the first 2 advantages to trigger the linked quality of the first weapon 3. He spends 2 other advantages or 1 triumph to hit with the second weapon 4. He spends 2 other advantages to trigger the linked quality of the second weapon Many advantages required, but it can be done and deliver a devastating shot.
