Help with a Military tarp?

Im looking for a I guess youd call it "tarp". Im looking for the ones that are more tattered that blend in with your surroundings to where no one can see your camp. Like the ones you hang above your site. Just thought itd be cool to own one. There used in the military to hide there set up. Like In The Army Now. Didnt know if those were actually open for purchase or not tho:P
