I was watching a video on youtube of a match. I saw a guy with a Victory II first shoot at a ship with his front arc, then shot again out of his front arc at 3 squadrons of X-wings.

Now my understanding of the rules are this is not allowed you would have to shoot at the ship with one arc then shoot with another arc to hit the squadrons.

Am I understanding the rules correctly?

Please note I did not get the ships build or the mission objective. So I believe if he had Gunnery team he could shoot out of the same arc twice. I think there is also a mission objective that allows you to assign that ability to a selected ship.

So if you take away the 2 upgrades that I am not sure about Gunnery team and the mission objective am I reading the rules properly?

In a nutshell, Yes. You can not attack with the same zone twice unless you are playing advanced gunnery (and even then it's only one ship) or you have the Gunnery Team as you mentioned.

Not all video battle reports are right.

can only shoot from a hull zone once unless you have a gunnery team or advanced gunnery objective
