I don't see all the icons/units when I am making a flanking move, so that kind of argument is invalid.
Of course I'm not interested in iformation about every bullet, just in the fact, that one of the units from the other maneuver group get's in trouble.
The reality has nothing to do about it, because in reality the leader of company A don't need to worry about company B, but it's a game and I'm only one.
