I think civilians and other non-military paraphanalia (scuze spelling) eg cars, wagons, farm animals etc are out of CMs scope because of the extra computing power needed to do them.
Going off track a bit here, I would jut like to add my favorite civilian in war movie scene: the elderly woman calling out for a taxi in Arnhem from 'A Bridge too Far'.
Anyway, it certainly would add great tactical value and realism, but then how far do we want realism to go, do we really want to experience what the real soldier saw, exploding bodies, blood and gore (not Al) etc etc... you know what I mean.
