A disrupted unit is NOT made combat ineffective---
it can fire, it can assault (if it's already in an assault hex)---only it cannot move into enemy hex, and it can only move 200yrds over 15 min.
A demoralized unit IS combat ineffective---
it cannot fire, it can only defend in assault hex, it must FLEE if it fails recovery (which it must attempt--unless playing FOW gamey tricks.....
...)
and given that it has lost cohesiveness...it can run for the hills/trees....and then must pause and try and recover....
(I wonder if the opponent should retreat fleeing units....maybe dice for each....)
