Smart Gun

A smart gun is a gravity pulse weapon which fires smart ammunition. The most common caliber smart gun fires smart needles. The gun itself contains a laser targeting system and microcomputer. The user paints the target with the laser and the microcomputer programs the smart ammo to hit the target which has been painted. The target acquisition can be geographical, that is hit that spot on the wall or hit that bottle, or it can be objective, hit that large IR producing mass, which happens to be a man, even if it moves to a new location.

The gun itself fires the projectile using a gravity pulse. Most smart guns are not capable of firing a direct graviton charge at a target, though it is possible to have this feature added to any gun which fires Large Caliber Smart Ammunition (LCSA) or larger caliber rounds.
Larger caliber smart guns, those firing ammunition greater than 15mm, can also fire a greater variety of ammunition types, including the tangler, shot, APEX, and smart loads.
Combat Smart Weapons are versatile, multi-barrel weapons which can fire both smart needles and 20mm rounds, some of which are smart. The top barrel can also be used as a gravity direct fire weapon

The bottom barrel fires standard smart needle ammo. The weapon includes a powerful targeting laser for long ranges and a complex sensor package for a full range of targeting acquisition possibilities. It has a data link to allow it to be used with a combat helmet or cybersuit HUD system.
Combat Smart Weapons are the standard issue for Rangers and also used by Legionnaires, when not fighting in warsuits.
