Using the One-Shot system, under development by the Defense Advanced Research Projects Agency (DARPA), a new electro-optical system will calculate the ballistics for him, telling him where to aim and ensuring a perfect shot — no matter the weather conditions…

It will measure atmospheric conditions, account for the weapon’s maximum effective range and include GPS coordinates. It’s also supposed to communicate with the rifle scope, informing the gun itself of the aim point offset and expected crosswind.
