Fictionalized NSNs It is not unheard of for fictionalized numbers to be referred to in works of fiction as if they were NSNs -- especially in military science fiction. This can be seen as a variation on the false document technique, something used creatively in order to lend a strong air of authenticity. For example, the M41A Pulse Rifle, from the movie Aliens, has been referred to as having NSN 3055-00-721-4790, as if it were real (though its FSG is incorrect: 30 is mechanical power transmission equipment, while 10, weapons, is probably the right FSC). The hull patch kit that the player must use in the sci-fi computer game Mission Critical, to stop the decompression emergency, has an NSN stenciled on the side of its plastic box.
