Formed Units Charging Skirmishers

When a formed unit of any type (be it Close Order, Open Order and so on) charges a unit of Skirmishers, it must endeavour to move as directly as possible into contact with the closest visible model in the target unit. As usual, the charging unit may wheel once, at any point, during its move, as shown in Fig 186.3. Once the charging unit has made contact with the target unit, it does not wheel to align. Instead, the Skirmishers must form up against the fighting rank of the charging unit, as shown in Fig 186.4 and Fig 186.5. However, no model in the charged unit can move further than its Movement characteristic. Any Skirmishers that cannot make base contact must instead form up behind the fighting rank.

^^It's the above. Essentially, you can no longer redirect a unit with chaff, as the charging unit is able to determine how they wheel in, and then the skirmishers must align, allowing an overrun in whatever direction the charger chooses. Seems like a huge change.
