Troops attack with the normal number of Attacks: +1 if double armed or +1 because they are assaulting that turn. All attacks automatically hit a stationary vehicle. Vehicles moving 6" or less in their previous turn are hit on a 4+. Vehicles which moved faster than this are only hit on a 6. WS counts for nothing in this case! Skimmers can only ever be hit on a 6 regardless of whether they moved or not, unless they are immobilised in which case, they are hit depending on the distance moved in their previous turn.
