How to punch through all the layers in Adobe Illustrator?

So I have this image as vector : http://is.gd/35ph9R

And this grunge image as vector : http://is.gd/wWyKvl

I can easily mask the grunge part from the image in Photoshop : http://is.gd/Kctrqs

But when I try to do this on Illustrator with pathfinder always get funky results : http://is.gd/zSi8Tw

I can use the Pathfinder tool on simple one object at a time, subtract from front etc..

But how can I make this with these all layers and groups
