Smart weapons are those that utilize targeting mechanisms external to it. A good example of this is the Maverick munitions, which use a separate laser to designate the bomb's target. The source of this laser can be a plane, a soldier close to the target, or even an orbiting satellite. With the target painted by this laser, the Maverick can adjust and refine its path to the target based on the laser's reflection. Another type of smart weapon is one that uses a TV camera to feed visual information to a human technician. Using this information they could make small or great course changes throughout the flight, right up until impact. A benefit of both these types of guidance is extreme precision. Since many modern conflicts take place among non-combatants, these high tech weapons can ensure that only the actual target is affected by the attack.
