A small unmanned aerial vehicle powered by a fuel cell soon may be soaring over distant battlefields. Lightweight tactical robot aircraft are vital for supplying ground forces with immediate reconnaissance information, but their battery-powered engines limit their operational time.

There are tens of thousands of defenders of the Internet infrastructure who must be vigilant around the clock, everywhere. Meanwhile, small teams of attackers can strike undetected whenever they choose, from wherever they may be in the world. This is why the contests between the defenders and the aggressors meet the definition of asymmetric warfare in its extreme form.
