During the Remaining Moves sub-phase, models with this special rule may drop a bomb unless they are fleeing or have declared a charge that turn. To make a Bombing Run, select one unengaged enemy unit that the Sky-junk moved over in that turn and place the large 5" template anywhere over the target unit (but note that it cannot cover friendly models) and roll for scatter and damage as for a stone thrower from the Warhammer rulebook with Strength 4(8), Armour Piercing (1) and Multiple Wounds (D6) special rules.
If a misfire is rolled, roll a D6. On a 1, the Sky-junk suffers a Strength 6 hit with the Multiple Wounds (D3) special rule. On a 2-3, centre the 3" template over the Sky-junk before scattering it and resolving damage as normal. On a 4-6, only the model under the template's central hole is hit, suffering a single Strength 4 hit.
