[Ogre] infantry splitting attacks

[David Morse]

A case can be made that a lone squad of infantry in an overrun attack
may take two strength-1 attacks instead of its normal strength-2
attack.  Here are the relevant sections of GEV for your consideration:

   GEV 6.09 Multiple Targets.  Only infantry may divide its attack
   strength between targets.  For instance, a 2/1 infantry could attack
   on GEV at 1-to-1, or two different GEVs at 1-to-2 each, or the same
   one GEV at 1-to-2 each time.
       Note: No other unit has this flexibility in dividing its
   attack.  Note: Infantry cannot divide itself into attack strengths
   other than whole numbers - no fractions.

   GEV 6.131 Attack strength in overruns.  Attack strengths of infantry
   and Ogre weapons are doubled in overrun attacks, whether they belong
   to the attacker or defender.  [...]

So, depending on the order you apply the no-fraction restriction and
the doubling, makes a big, big difference.  For example: a lone squad
in clear defends against two squads making an overrun.  What's the
outnumbered defender's chance of surviving?:

Single 2-1 attack: defender wins 11.9%.

Split 1-1 attacks: defender wins 58.4%.

As seems to be the established procedure for rules questions not
resolved by GEV, I checked Ogre Miniatures to see if a slightly
different turn of phrase clarified the situation, but as far as I can
tell infantry platoons in Ogre Miniatures can't even split fire
without physically separating into different minis during the movement
phase, so there's really no advice in there on how to resolve this
dispute.
