Hi,
Believe that they could fight as skirmishers and in line.
Therefore basing can be a problem.
Duplicating the figures on different size bases works for me.
I've got 2 battalions based in 2 rank deep lines in close-order plus the equivalent of 1 battalion based in skirmish order.
This allows me use the skirmishers on their own in a skirmish screen where the scenario requires it.
Alternatively this also allows me to use the 2 battalions deployed in skirmish order i.e. half in skirmish order with the other half remaining in close order behind.
This way I can way I've got full flexibility.
I've not yet done this my my British Light Infantry battalions but will eventually get round to doing that too.
Hope that helps.
Cheers,
Paul
