Firing on Fleeing Units

[plloyd1010]

So---Can you?  Can you exercise Opportunity Fire on a unit which failed his Demoralized Recovery
  and is forced to flee out of range?

Yes you can. The rule says:

A moving unit (and any leader moving with it) or leader moving without an accompanying unit may be attacked in any hex(es) within enemy range that it enters along its movement path. This includes fleeing units.

I don't, mostly because I don't like tying up units which can do something more useful. If you wish to give me special credit, I'll claim military convention and moral abhorrence.
