It's a great concept for having unmanned remote control vehicles in military applications........ Nikola Tesla envisioned this over a hundred years
ago (1898)
www.yurope.com... ....... it was Tesla that invented remote
controlled vehicles with this very purpose in mind!! He tried to 'give' this idea to the military but at that time no one really understood it and
just pushed it off as 'nothing'. It's interesting that his first "automaton" was a submarine.
