Even through traumatic brain injury has the word "traumatic" in it, it's often the case that soldiers in combat are exposed to things blowing up that leave mild to moderate brain injuries that go undetected. DARPA's new field blast gauge is designed to help medics tell exactly how much blast exposure someone has, and whether they need treatment.

DARPA's looking for a way to give soldiers on the ground more direct access to air support, and the solution that they've come up with involves a nifty-looking set of holographic sunglasses.

DARPA decided to take a stab at crowdsourcing a new concept vehicle on a common chassis designed for both combat reconnaissance and combat delivery & evacuation. They allowed the public to provide feedback and vote on different proposals, and here are the winners.

Stealth drones save troops, but they get shot down easily. DARPA's given the engineers at Boston Dynamics the green light to build the world's fastest four-legged robot based on a cheetah. Sounds like Beast Wars' Cheetor to us!
