A couple questions:

By Kingsguard, in Rules

If I have an MPL-57 Barrage Trooper in my Fleet trooper Squad, he can choose to fire the standard DH-17 pistol instead right?

Do I roll the dice for the standard trooper attacks and the Heavy weapon attacks separately? Or do I roll them all together? If the former, does that stay the same if they are targeting different enemies?

If my Barrage trooper is the last remaining unit in the squad, is he forced to lose his weapon if promoted to squad leader?

Can Darth Vader gain suppression tokens since he has no courage value?

You resolve attack pools one at a time. So if you’re targeting the same thing, roll all at once. If targeting different things, roll one group, then roll the defense dice. Then roll the next group followed by defense dice, and so on.

Yes, he loses the weapon because that sculpt has been removed.

No. The “-“ means he’s immune to suppression and does not receive any.

Thanks!
