light/legere battalion in loose files, open order and extended order

the diagram shows an infantry battalion adopting; loose files, open order, and then extended order...
these intervals did vary form army to army.. but in the case of the game, a convention or general rule is necessary.

notes: so that people know which way around their units are...there are four bases to a standard infantry unit, the black base is the command base, the red one the grenadier/"heavy", and the green one is the voltigeur/"light" base.
