Linebreaker Bombardment

Use this Stratagem in your Shoot phase if a
Thousand Sons Chaos Vind. from your army is
within 6" of 2 other friendly Thousand Sons Chaos
Vind. The Vind. cannot fire their demolisher
cannons this phase: instead, select a point on the battlefield within 24" of all three vehicles and
visible to them. Roll a D6 for each unit within 3"
of that point. Add 1 to the result if the unit being rolled for has 10 or more models, but subtract 1
if the unit being rolled for is a Character.
