Fast 0 #1 June 10, 2009 I want one of these... QuoteAs the 25-millimetre round is fired, the gunsight sends a radio signal to a chip inside the bullet, telling it the precise distance to the target. A spiral groove inside the barrel makes the bullet rotate as it travels, and as it also contains a magnetic transducer, this rotation through the Earth's magnetic field generates an alternating current. A patent granted to the bullet's maker, Alliant Techsystems, reveals that the chip uses fluctuations in this current to count each revolution and, as it knows the distance covered in one spin, it can calculate how far it has travelled. The rifle would allow a soldier faced with a sniper firing from a window to take a distance measurement to the window, add a metre, fire through the window, and have the round detonate 1 metre inside the room. The same method could be used to fire behind a wall or over a trench. http://www.newscientist.com/article/mg20227116.900-radiocontrolled-bullets-leave-no-place-to-hide.html~D Where troubles melt like lemon drops Away above the chimney tops That's where you'll find me.
