The supersoldier (or super soldier) is a concept soldier, often fictional, capable of operating beyond normal human limits or abilities. Super soldiers are common in military science fiction literature, films and video games. In 2012, DARPA was reported to be developing an externally powered XOS exoskeleton design for greatly increased strength and endurance. Fictional supersoldiers are usually heavily augmented, either through eugenics, genetic engineering, cybernetic implants, drugs, brainwashing, traumatic events, an extreme training regimen or other scientific and pseudoscientific means. Occasionally, some instances also use paranormal methods, such as black magic or technology and science of extraterrestrial origin. In entertainment, the creators of such programs are viewed often as mad scientists or stern military personnel depending on the emphasis, as their programs would typically go past ethical boundaries in the pursuit of science or military might.
