Attrition rules/limits on number of recoils for an element

I did once post something about ‘fatigue’ (see fanaticus.boards.net/post/10629/ ),
which basically was about fresh troops who haven’t fought or been shot at before
gaining a +1 (indicated by a ‘fresh flowers’ marker), those that have been in combat
becoming tired (no marker, which is the current default DBA state), and those that
recoil being -1 for fatigue (indicated by a ‘dropped shield’ marker - the reverse side
of the ‘fresh flowers’ marker above)...
...but I don’t think this is what Simon is referring to, as this was meant for DBA and
not DBR or DBN, although it could be adapted for them.

He seems to be referring to troops becoming broken/routed/destroyed after they
have been recoiled a certain number of times (say 3 times perhaps?).

The problem with this is it would make weak troops with a combat factor of 3 or less
even weaker than they already are...they are easily recoiled by more powerful troops,
who would get an extra way of killing them, by doubling their score and by multiple recoils.

I suppose you could arrange things so that certain weak troops merely recoil (or flee?) when
doubled, and are only routed/destroyed once they have recoiled a certain number of times...
...but it still means having on-table markers or fiddly paperwork to record their status.
