I have never been in a scenario where gun hits counted. Granted I have not everywhere. If you put the reality situation into it, one of my former teammates put it quite well at one time. If you have a situation with limited ground i.e 30 acres, for a round figure, and %100+ casualty rate with hundreds of people on the ground at any given time and unlimited fresh troops, after an hour or so you will not be able to sneeze without stepping on a functional weapon. As far as Bunker tanking, that is a good chance for flanking or using special weapons. I know most scenarios have a rule where you hit a bunker with a bazooka it is taken out with everybody in it.
