A super soldier (or supersoldier) is a concept soldier capable of operating beyond normal human abilities through technological augmentation or (in fictional depictions) genetic modification or cybernetic augmentation. Soldiers that obtain greater-than-normal physical abilities by wearing powered armor or a technological exoskeleton (such as the Mobile Infantry in Robert A. Heinlein's Starship Troopers novella) are a distinct, but related concept and the two often overlap, as is the case for Halo and Warhammer 40,000 universes, for example.
