From what i have heard regarding urban camo, etc, it's going to be some kind of BlitzKrieg thing. They are already spying on us, so hiding the guns probably wont do much good - unless you plan it out like a super spy and bury them in a deep hole in the forest or desert. But then you still need to know the gps coordinates and then there is always a record of moving objects from their "satellites" in the sky.
By the way, can you see the weird blinking things in the sky that arent planets, or stars, or airplanes/helicopters. They dont move, and they seem to flicker.......I want to move to washington!!! aghhhhhhh STATE THAT IS, not "Washington, D(istrict) of C(onspiracy)!
