From “Aliens,” to video games, to TV shows, the future of infantry warfare has always been clear: Tomorrow’s soldiers will have some kind of cool eyepiece that tells them their locations and those of their compatriots; includes some kind of overall tactical picture; maps; the latest orders or messages; and enhanced vision or a FLIR-type picture. They’ll have some kind of awesome gun that shoots around corners, or fires laser beams — or both. They’ll have incredible, lightweight armor and, depending on their units, jet packs.
The Army has poured billions into this endeavor. But the program has always run up against the fundamental problem of providing power to the systems. Until there is an entirely new way of providing enough power with a minimal weight increase, this Starship Troopers goal will just be a drain on resources.
