Technology like this can let an average, barely trained soldier, compete with top marksmen. It is much easier to keep a laser dot on a target then to judge wind, distance, rotation, temperature, and a host of other factors, not to mention the need to anticipate your targets motion. If they can perfect the technology it could be a real game changer.

"Engineers at Sandia National Laboratories have invented a bullet that guides itself to the target.
Sandia has wide expertise at miniature technology, and the bullet works like a tiny guided missile.
The patented design doesn't shoot straight. Instead of a spiral rotation, the bullet twists and turns to guide itself towards a laser directed point. It can make up to thirty corrections per second while in the air."
