Fog of War

[cjsiam]

We use it with the proviso that ALL DEMORALIZED UNITS MUST ROLL after the turn ends.
Point being your exact observations...it gets gamed to leave units in hexes...
Demoralization -- you've lost control of the Unit...it is going to behave as it wishes, not patiently wait there as you would like.

So once the FOW (I think it should be call "Friction of War"...Fog would be hidden units...just saying...) is rolled...both players
then have to roll for all Demoralized units that have not been activated...WITHOUT the help of officers....(if you wanted help, you 
should have tasked the officers during your turn cupcake...)
As well...OFFICERS are NOT units...they don't get to roll (see advice to cupcake above)....

This way---if he's gonna flee---he's gonna flee.....
You do NOT have control over the behavior of the demoralized unit.

I play by VASSAL (being in Thailand...), once FOW is rolled, and after we advance the turn marker---AND BEFORE WE CLEAR MARKERS---we go over
battle field to assure Demoralizations are rolled...
I find this a more palatable approach to simulating the "Friction" of war which seems appropriate---enforces organization and prioritization of attention...
things commanders DID have to deal with.
