I could really use more wrecked tanks, cars and other vehicles. Also bodies that are not covered with blanket. Bodies should be with weapons they carried, and in many different positions.
I used "setdammage" to make a ambush site where players found dead bodies (I killed those men at the same moment when the mission started) and wreck of one M113. Then I noticed that if I wanted to make destroyed tanks with same method players could hear the explosions.
I believe that there are lots of people who could use this kind of addons.
