The title, “Smart Bullets” Are Designed To Chase a Fleeing Enemy, is a bit misleading, but the article does explain what the military’s trying to do to improve soldiers’ aim:
Tests conducted in 1990 at Fort Benning, Ga., found the U.S. Army had a problem. Its soldiers’ aim was off.
Way off. On a normal shooting range, basic trainees can hit targets about 220 yards away 80% of the time. But under confusing conditions mimicking the “fog of war,” Army researchers found the accuracy of infantrymen hefting M16s plummeted to just 20%.

Mr. Shisler says the Fort Benning simulations, in which soldiers ran in place to raise their heart rates and then fired on pop-up and moving targets, helped persuade gun designers they needed a radically new approach to killing or wounding antagonists.
This reminds me of my favorite ergogenic-drug story: Olympic biathletes were using beta-blockers, heart medication, to bring their pulse down after cross-country skiing, so they could shoot more accurately. I’m not sure how they brought it back up to ski again.
Anyway, the Army’s trying to side-step soldiers’ poor aim with the XM29:
The first smart-weapon to combine those concepts is the XM29. The Army is investing more than $130 million into the blocky, black gun, which fires both regular rifle bullets and air-bursting 20mm rounds that scatter metal fragments at a predetermined distance.
The gun, whose marketing tagline is “No Place To Hide,” packs some $28,000 in electronic gear, including a laser range finder that measures the distance to an enemy in the cross hairs. A ballistic computer on the gun then programs an electronic fuse inside the round, which counts the number of rotations it makes as it hurtles through the air, exploding at a precise distance.
