Re: Marksmanship

"but if we read historical accounts of skirmish battles between seasoned
troops (esp I'd say eastern front WW2, Korea, etc), we will find that
many
engagements of hostile targets occur successfully out beyond 200m."

Maybe so, but who designed and adopted the first modern assault rifles
with
under 200 meter ranges in mind?  The Germans and Russians (the MP/SG 42
and
its Russian cousin the, AK series).  Long range fire can be effective,
but
mostly when it's the SAWs firing,  not the personal weapons (a lesson
the
Germans digested during WWI, hence the MG34 & MG42 and the tactical
doctrine they built around such excellent weapons).

Of course we're also talking sci-fi here so all those HUDs,
gyrostabilizers, laser pointers, etc, should maybe count for something.
