E3 2006 Teaser Trailer goof

I think I found a goof on the Teaser Trailer. At the end of the Trailer where the video is full of game graphics for Call Of Duty 3, u r with a soldier, when the soldier is shot down and everything is in slow motion, see his left hand, his left hand goes threw the ground. Here is the video if u want to see it... http://www.youtube.com/watch?v=ku43KSZZzxg .... If this video is to small for u here is a bigger video but let it take time to load... http://www.gametrailers.com/player.php?id=10422&type=mov&pl=game
