More specifically the Gauss Flux Arc. When you roll a D6 for each unit within range, is that the number of hits and you just roll to wound? or the number of dice you roll to hit, and then take the successful ones and roll to wound?I always thought it was the former, but I got into an argument and my friends say it has to be the latter. While the codex does say number of shots, it just doesn't make any sense for the way the weapon appears to be used.
You roll (for one unit) the number of shots that are fired. Then this is treated as any other ranged weapon and so you must roll for to hit and then to wound on the successful hits. Once you have completed shooting at one unit, you move onto to shooting the next unit within range and so on until you have taken shots at all units within range.
I should also point out, you roll to see how many shots are fired for each unit that you target, as opposed to rolling one D6 for all units.

For example, I have 2 guardsman squads in range. I roll 2 D6 and get both sixes. I then roll six "to hits" for one squad and score 4 hits. I then roll four "to woundss". I then do the same for the other squad.
Of course, I'd previously annihilated their allies with the particle wip!
