I think it is something missing: A behaviour mode between:
-the COMBAT mode (they crouch, they need hours for advancing a few meters, even if it is obvious that there is noone)
and
-the AWARE mode (they run all the time and almost never take cover!)
I think we really need something between, with soldiers STANDING, not always laying down, but advancing SLOWLY. For urban fight for exemple or moving in a place were things could quickly became dangerous!
