If a unit is broken due to a charge and shoot, when does it break?

A) does it break immediately I.e before the charge move is made
B) does the charger make contact, then the unit break after the first round of impact. Obviously the unit won't fight at impact

It makes a difference to where the charging unit will end up

The sequence of events would suggest b, but I'm not certain

It is clear in the turn sequence.  Routs occur after charge moves.  So b).

Would it be rude to mention this is covered in the clarifications 

Not rude but informative as its covered in a bit more detail there.

Ah, clarications. More to read! Thanks
