Sighting in a target through the scope of a high-caliber rifle can be a bit more complicated then it sounds -- snipers have to account for cross-winds, range and a whole host of external factors that could put their projectile off course.

It isn't easy, and the required calculations can seriously slow down a shooter's time to trigger. The solution? High tech laser-equipped sniper scopes, of course. DARPA has actually been working on this problem for quite some time, and calls its' project One Shot.

Previous iterations of the targeting system helped shooters increase their chance of hitting their mark by a factor of four, but suffered from short battery life, range finder accuracy errors and overheating problems.

DARPA is putting its faith into Cubic Corporation to overcome these faults, awarding the firm with a $6 million contract to develop a "compact observation, measurement and ballistic calculation system" that it calls the One Shot XG. Like its predecessors, the XG is designed to give the shooter a offset aim point to counteract the environmental conditions that would impact bullet trajectory. DARPA is hoping to see ten weapon or scope-mountable field devices within 15 months. Consider this fair warning, Segway bots.
