===Morale===
The thing that determines if your units stay and fight or turn and run for the hills.
Moral tests are taken when a unit loses 25% of the models in the shooting phase or it has been beaten in combat. Upon failing a moral test units will fall back, simulating the unit routing or retreating to a more advantageous position. A unit will continue to fall back during each turn until it makes a successful moral test to regroup. Units falling back from combat are also subject to their opponent making a sweeping advance test to finish them off, where both units compare their initiative + die roll. If the unit that is falling back has an equal or higher result, it escapes, while if the unit that is trying to run them down has the higher result the falling back unit is wiped out. This can be pretty brutal and it can be a serious punishment for units that were thrown haphazardly at the nearest enemy unit.
