Cluster Munitions

If the attack scores one or more hits against an
enemy unit, the next closest unengaged enemy
unit within 6" of the original target immediately
suffers D3+1 hits with Strength 4 and
Armour Penetration 1.
If there is more than one eligible unit, the
Active Player chooses which is hit.
These hits are considered Special Attacks and
aren't affected by Cluster Munitions.
