|The hexgrid in our 6mm Napoleonic games.|
The diagram below shows the fire arc for both types of orientation, with a reduction in fire power in some hexes which are only "half-covered".
However, after reading the following post on the Battlefields and Warriors blog, and reading the house rules written by feloow wargamer Norm Smith, I realized that this can be resolved in another manner as wel:
- Whenever a unit is shooting, it can distribute its fire only within a 120 degree fire arc. So effectively, it is choosing its orientation at that point, but it is not necessary to orient the figures as such. Just don't shoot at different targets more than 120 degrees apart.
- When judging flank attacks, there is a flank attack if the unit is attacked from 2 different non-adjacent hexes. Again, actual orientation of the unit is unimportant.
