There is a line in every ship's description, the Ship's Complement, but it never describes what exactly each member of the crew is capable of. For example, pg 260-261 of the CR, the ILH-KK light freighter lists a pilot, co-pilot, and engineer, but the ship has 5 weapons listed also but no gunner in the ship's complement. So can the pilot, co-pilot, or engineer fire these weapons?
Pg 263, the Starwind Pleasure Yacht has a couple of similar weapons (the dorsal and ventral turret mounted laser cannons, compared to the port/starboard turret mounted ion cannons of the ILH) but the Pleasure Yacht has 2 gunners listed in ship's complement beyond the otherwise same listing as the ILH.
If the gunning is restricted to the pilot or copilot in the ILH, can they (pilot and copilot) also do it in the Pleasure Yacht if there are no gunners? Can someone at the "engineer station" (whatever that may be) fire the weapons in either ship?
In Suns of Fortune, pg 111, the J-type has 2 dorsal turret-mounted retractable dual laser cannons, and a complement that includes 1 gunner. Obviously 1 gunner can't fit into both stations, but they have the linked quality, like the ILH's turret ion cannons
What are the guns that Han and Luke use in the Millennium Falcon considered? They don't seem like they could be used by the pilot, since there is a chair for each gunner, and they seem to be turret-mounted.
Also, with the facing becoming somewhat of a question of late, can a pilot fire a weapon that is aft-facing? Or port/starboard facing? It's all kind of confusing somewhat...
