You can actually own a bazooka if you fill out the correct paperwork. It is a NFA item as regulated by the ATF and each round (aside from rounds containing no explosives) are their own NFA regulated item. Each bazooka and explosive round requires a long approval process, $200 fee, fingerprinting and passport photos. Each explosive round must be stored in a ammunition bunker built to strict ATF regulations and you must inform the ATF of each round fired.

Rifles and handguns sure are doing quite a number in the middle east and they worked in vietnam.
