It's not just unmanned aircraft that are getting smarter. So too are basic infantry weapons. Consider the XM-25 Counter Defilade Target Engagement weapon system, which for several years has been going through tests -- including real-world evaluations in Afghanistan -- to show off its ability to strike at targets hidden behind walls and inside buildings. It features a combination of laser rangefinder, target-acquisition software, and programmable, air-burst ammo, all of which have been assembled by hand during the experimental phase. But the Army seems poised to decide by about August 2014 on whether to remove the X designation and send the just plain M-25 into initial low-rate production (of around 1,100 weapons), bringing it closer to operational use.
