Sorry if these have been answered before, but my group had some questions and I wasn't sure what the answers were. Please help.
1. When you perform a combat check with vehicles weapons, do you pick one of them or may you fire all of them in one activation? It says weapons (plural), not a weapon (singular). For example, take an A-wing:
Weapons: Port-mounted light blaster cannon (Fire Arc Forward; Damage 4; Critical 4; Range [Close])
Starboard-mounted concussion grenade launcher this weapon's entire profile uses personal scale, not
planetary scale. (Fire Arc Forward; Damage 1 0; Critical 4; Range [Close]; Breach 1, Blast 8, Limited Ammo 15).
Chin-mounted twin heavy blaster cannons (Fire Arc Forward, Damage 5; Critical 4; Range [Close]; Linked 1 ).
Do I pick one of the three weapons or can I fire all three of them? If I only get to fire one of them, why bother having the weaker port-mounted light blaster cannon if I will never be firing it? Is it meant purely as a backup weapon in case the other one gets disabled/destroyed?
2. When Taking Cover you retain your defensive bonus unless the circumstances around you change so that you would no longer benefit from cover. What circumstances would apply? Do you have to leave cover in order to make a combat check, like peeking out from a corner to shoot, or tossing a grenade? Would this be a maneuver to step out of cover, an action to shoot, then potentially another maneuver to dive back into cover, OR can you just stay in cover from last round and shoot, saving your maneuver for something like aiming?
