Each time this unit Advances, do not make an Advance roll. Instead, until the end of the phase, add 6" to the Move characteristic of models in this unit.

Once per battle, after this unit ends a Normal or Advance move, you can select one enemy unit (excluding MONSTERS and VEHICLES) that it moved over during that move, then roll one D6 for each model in this unit: for each 2+, that enemy unit suffers 2 mortal wounds.
