I have a question about gunner, and if it has been answered before, I apologize. I was using gunner on the Hound's Tooth, and the way I read the card, gunner can be used even if the first attack is made with the primary weapon, since gunner doesn't say that it triggers if a secondary attack misses. Then, if the first primary weapon attack misses, you get another entirely separate attack with the primary weapon. Can someone please clarify this for me?

The card reads "After you preform an attack that dose not hit, you may preform a primary weapon attack. You can not preform another attack this round" (FAQ version) So if any attack misses (Primary or secondary) then you can do a seperate primary weapon attack (FAQ states that yes it is a spreate attack). So the player can trigger it on a primary or secondary since it dosnt specificly state that it has to be on a primary attack. hope that awnsers your question.

Gunner can be used after any "attack" misses.

The Gunner must use the ship's primary attack with this attack being treated like a brand new attack. No other attacks may be made by the ship.

You can use Gunner (and the crew version of Luke) to make another attack after any of your attacks misses.

The new attack has to use your primary weapon.

The new attack can be against any legal target for your primary weapon.

Typically Gunner is used to secure attacks against an elusive guy (aces) by making them roll twice with an equally nasty attack. Any attack triggers it but typically only people that bring gunner arent using secondary weapons.

It is a completely separate attack though so if you wanted you could have it hit a different target, though i cant think of why you'd change unless theres more than 1 ship with "when defending" procs you want to get rid of. Usually such procs arent nice so not sure why you'd want to proc them with the same ship lol

I'd guess the place you see Gunner attacks directed at a new target would be when it's on a PWT ship. The first attack may strip enough resources (tokens) on one target that it is now much more vulnerable to attack from allies so the second attack is directed at some other prime target.
