Unmanned

The US Army recently debuted the first armed unmanned ground system (UGS) in Iraq, marking a new milestone for unmanned systems.

The march of the killer droids continues, with news that a US robot helicopter gunship has passed a significant milestone - engine testing.

This success means the robot can head for production - once avionics and sensors arrive. The cyber-copter in question is the RQ/MQ-8 vertical takeoff and landing tactical unmanned air vehicle (VTUAV) commonly known as "Fire Scout".
