What I thought was funny was that they were shooting bullets at smokey. I mean I guess a it is a pretty natural reaction for the mercenaries to shoot at something that is attacking them, but what good would it do? Seems like they would just end up shooting each other.

So far it seems like sound waves are the only thing that can hurt (or maybe just repel) old smokey. The sonic fence blocked it and when smokey was pulling Locke down that hole they threw dynamite down the hole and I thing it was the sound waves produced by the place that scared it off more than the actual explosion.

Anyways... maybe they were a lot more of the mercenaries and the group we saw carrying that one wounded guy was just what was left.
