Re: SG2/DS2 Unit coherency.

OK, so as best we can tell, the unit coherency rules represent a
combination
of communications ability and doctrine.  Which leads to my next
question:

Do we think that those are accurate limits?  I realize that many
nations'
militaries may have different procedures, but that's what I'm getting at
-
should differently equipped/led nations have different coherency
restrictions?
How would we work out the benefits/penalties for various separations? 
Are
there coherency rules between squads - must the command elements for
each
squad/unit be w/in a certain distance?	This may be better represented
in DS2,
where you can easily have separations of kms.  Should there be different
unit
coherency rules for different terrain (SG2 ex: Normal = 2", Poor = 1",
Difficult = 0" (base-to-base))?  From a previous post (John Atkinson's,
I
think), current US doctrine was min 5m, more if possible.  How much
more?
Does anybody know what last Soviet doctrine was?  I can't find my OPFOR
handbooks - I lose everything when I move. *grumble*  I'm asking these
questions because every so often, people send units jaunting out across
the
board, all by their lonesome, and other mini wargames that I've played
(Spearhead, Command Decision 2nd ed, Striker 2) all had essentailly unit
coherency rules for all levels.  They were based on communications
abilities.
I'm wondering if such a thing does or should exist in DS2/SG2.

BTW, was the SG2/DS2 conflict over 'what's an APSW?' ever resolved?  If
so,
could somebody email me the answer?
