Select: a target; imagine a straight line 1mm wide from the weapon out to its maximum range, crossing the target's base at the point nearest the firing model
Result: the nearest unit with its base under the line takes a number of hits given by the weapon's Dice value
That unit destroyed: the next nearest suffers hits equal to the Dice value reduced by the bracketed number, floor 0
Repeat until a unit survives, no unit remains under the line, or the Dice value is 0
Targeted Attacks only against the nearest unit; location is random for each later unit hit
Any terrain piece beneath the line is treated as a unit when finding the nearest one; if terrain is nearest, the beam goes on as if an enemy unit were destroyed (lower the Dice value, then hit the next unit along the line)
Destroying Terrain special rule in use: hits land on the terrain as usual, and the beam continues and lowers the Dice value even if the building survives
