When greenskins get together they start to pick fights, bicker and misbehave in all sorts of appalling ways. Even at the best of times, squabbling in the ranks can send a greenskin horde into disarray. One moment a mob is striding purposefully towards the enemy, and the next it is brought to a halt whilst two or more greenies settle their differences.
Testing for Animosity
At the beginning of the movement phase (before declaring charges) in each of your turns you must test for Animosity. All of your units on the table are subject to Animosity, except:
Fleeing units.
Units in close combat.
Units of fewer than five models.
War machines and chariots.
Units of Snotlings, Trolls, Giants and Black Orcs.
Starting on one side of the table and working through your army, roll a D6 for each unit that is subject to Animosity and consult the Animosity table (shown to the right).
Characters and Animosity
Obviously, being single models, characters do not test for Animosity if they are alone. If they have joined a unit, they are bound by that unit's Animosity test and must act accordingly.
