Time has an article about how “Super Soldiers” may no longer be science fiction:

Imagine bad guys able to fight without sleep. Or enemy soldiers with hardware implanted in their brains that makes them better able to target U.S. troops than U.S. troops are able to target them. How about future foes able to outfox GIs thanks to the “pharmaceutical intervention” that has improved their “brain plasticity”? Or American soldiers rendered flat-footed and lethargic because a crafty nemesis has been slipping lead into their food.
