If I remember correctly I think the h.e. rounds have a 15 meter kill zone and punch through some armor plate can't recall the thickness (help me out fellow vets) do remember the fragmentation is dangerous for a very long way off. You can literally see a group of them going through the air almost like shooting a potato gun . Very effective weapon!!! One thing the service does for you is ruin movies. Real explosive aren't much more than a puff of black smoke with hardly any fireball (C4) . Movies use gasoline. Also you don't see a rocket go through the air (at-4) just a boom on both ends. Obviously bigger on the receiving end.. I always laugh when someone tosses a genade and it makes a huge fireball in a movie.
