Any time there's a new technology that's sufficiently impressive, chances are someone's going to use it to make guns work better.
That appears to be the case with Google Glass, which tech/firearm company TrackingPoint is using to augment their laser-guided cybergun to allow soldiers to fire around corners and from behind heavy cover. You may remember TrackingPoint from the "3D video game-style teaser" video they released for their laser-guided smartrifle last year.
Watch the video up top to get a sense of how it works. Honestly, it really was only a matter of time before someone came up with this sort of thing; I feel like I've been using this sort of stuff in video games for years. One step closer to just having all our wars fought by robot proxies, I guess.
