This has been possible for years in the lab. The limitation was that it took to much computer power to work in the field. Recently when both CPU power and the programming became faster the size needed to work has shrank enough so it close to be able to use in the field. It takes two to work but it really does only take factions of the second to know where any shot came from and create a response. In any case, they work much faster than human reactions and a bullet would be returned before the snipers bullet would even arrive. It's all basic math and programming that is years old. Steve
