Since antiquity once a weapon was developed there were soon methods to counter it. Just as the shield and armor were meant to protect a soldier from swords and spears, today there are now countermeasures designed to stop smart munitions, which were first developed during the Second World War. While the United States has continued to develop even smarter bombs, including laser- and GPS-guided bombs, the latest efforts include those that could select targets automatically when dropped from an aircraft. Such smart munitions could maneuver in flight after being launched, but efforts have continued to counter such measures and this has included the use of jamming technology. In what is part of a seemingly never-ending "arms race," Russia is now reportedly developing software that is designed for use in precision munitions of defensive and offensive weapons.
