Panic Tests For Breaks
URL Copied!

Once all of the combats have been fought and all units that have been defeated have taken a break test, you must take a panic test for all your units which are within 12" of friendly units which have broken. This represents the spread of panic amongst the army as friendly units collapse and turn tail, leading to crumbling battlelines and possibly causing other units to flee as well. Panic is a special psychological effect, and the full rules for panic and other psychology are covered in the following section of the rules. However, it is worth bearing in mind at this stage that panic tests must be taken once all break tests are complete but before any fleeing troops are moved.
