"Some Dark Eldar vehicles are fitted with several underslung chains and barbed hooks, the better to gouge at the flesh of those they pass over - if the vehicle happens to snatch up a victim or two and drag them to their death, so much the better. a vehicle with chain snares causes D3+1 S4
AP- Hits on all unengaged non vehicle enemy
units that it passes over during the movement phase."
Does this mean every individual model or the entire squad? so if it goes over 10 models it has the chance to do 40 S4 hits? or if it goes over them it only does a maximum of 4 hits? Why can't gamesworkshop just specify this?
