Once fleeing troops and pursuers have been moved it is time to tidy up the formations of fighting units in preparation for the next phase. This will not always prove necessary, as much depends upon the casualties inflicted and combat results.
Remember, a unit must always contain the same number of models in each rank as the first, except for its rear rank which may contain fewer. The process of redressing the ranks is intended to ensure that this remains true following combat, and also affords victors the chance to adjust their formation slightly by expanding their frontage or lapping round as described below.
