“Our .50-caliber bullet can guide itself to a hit half a mile away”

For years, people have tried to come up with ways to steer bullets, and everyone has consistently said you can’t do it. And you couldn’t—if the bullet was spinning. A spinning bullet is too stable; you can’t apply enough force to turn it off its axis of revolution. The secret sauce is that our bullet doesn’t spin. It’s kind of like a musket ball, which doesn’t rotate, but with technology added to let us control where it goes.
When you're aiming at a target two miles away, the slightest perturbation could end up causing a catastrophic miss — not good enough for today's military. Until guns can aim themselves, snipers need the most accurate weapons possible. Engineers at Oak Ridge National Laboratory came up with a laser-guided correction system that ensures a shooter's crosshairs are always on the mark.
The new Reticle Compensating Rifle Barrel Reference Sensor measures slight disruptions in a gun barrel, automatically compensating for how they would impact a bullet's trajectory and adjusting the gun's crosshairs accordingly.

Chiara Daraio loves the pick and roll. As a former member of Italy's junior national basketball team, she knows that although the effect of the play is complex and devastating, its parts are simple. It goes like this: Daraio blocks a defender’s path, her teammate darts past, Daraio rotates away from the pursuing defender and waits, unguarded, for her teammate's quick pass and an open shot. Pick. Roll. Pass. Shoot. It's a straightforward process with a sophisticated result.
U.S. Army Special Forces soldiers will deploy with the XM-25 weapon this summer, so that they can shower enemies hidden inside buildings with lethal smart rounds. Veterans of the Afghanistan conflict who tried the weapon predicted it would be a "game changing" gun capable of taking out insurgents hidden behind cover, Military.com reports.
The XM-25 resembles a highly sophisticated grenade launcher that fires laser-guided smart rounds. The laser gauges a distance to target and allows the warfighter to set where the round will detonate, adding or subtracting increments of 3 meters from the laser-spotted point. Then the scope tells a microchip inside the round how far it should travel before exploding.
