Vibro-Cannon

To fire the Vibro-cannon nominate any point within its range (can be the ground, a model, etc). 
Do not roll to hit, instead roll a scatter die to see if you are on target. On the roll of a hit, it does not scatter. Otherwise move it D6" in the direction indicated.
Once you have established the final location, draw a line back to the weapon. Any targets along this line are hit and may suffer damage. 
Any model under the line is automatically hit. Assume the line is 1cm in width. 
Any models hit by a Vibro-cannon suffer 1 hit at a Strength equal to the target's own Toughness. 
A vehicle that is struck suffers 1 hit to the first location in the path of the beam that is touching the ground (legs, treads, etc.). Cannot hit aerial targets or skimmers.
See the armour penetration chart on Pg. 64

If a target is hit by Vibro-cannon beam a second time in the same turn, the save modifiers are doubled. In the case of vehicles, a further D6 is added to the penetration.
