Lazer tag

A laser designator is a laser light source which is used to designate a target. Laser designators provide targeting for laser-guided bombs, missiles, or precision artillery munitions, such as the Paveway series of bombs, AGM-114 Hellfire, or the M712 Copperhead round, respectively. When a target is marked by a designator, the beam is invisible and does not shine continuously. Instead, a series of coded pulses of laser light are fired. These signals bounce off the target into the sky, where they are detected by the seeker on the laser-guided munition, which steers itself towards the center of the reflected signal.
