Good old DARPA comes up with some comparatively solid practical ideas in between the really bat-shit crazy stuff.

The Land Warrior hardware can be used to locate its wearer too, but that might understandably get ditched by troops in a rout due to its bulk. By contrast, the IFPS is a little plastic cylinder that could be strung next to a soldiers dogtags, and allegedly allows him or her to be detected from up to 150km away without the use of GPS technology.
