A few years ago in my city, a biker gang used a similar weapon (military RPG) against a rival group. There was a party at the rival group's clubhouse. A guy climbed up on an adjacent roof and fired the RPG at the building. It went through a brick wall (directly through a corner IIRC) and exploded in the main room of the clubhouse. I actually think only one or two people were killed (it was full), but the place was completely cratered inside.
