Hello, Garry
My own person preference would be that from the flank or rear the unit would get the benefit of the attack column as the hits are to that part of the body, whilst from the front they get shot at as skirmishers. Once it has been done you are free to choose mod games for you. However I can see that this is open to interpretation both ways.
This seems also to better reflect actual historical practise, certainly for the British, where Wellington specifically ordered the formation of such units at Brigade level commanded by a major, and also for the French, who tended to organise such units under the command of a chef de battaillon.
