I read about something like this a while ago in a magazine... Some other company (or was it MIT?) also has a military contract to make combat suits for US soldiers...
It's basically an exo-skeleton, with the joints powered by hydralics (sp?)... This will give soldiers superhuman strength... And there a computer on the back of the suit which has GPS, etc... They said if the soldier is wounded, they can give a command to the suit and it will literally walk the soldier home by itself...
When I read that article, the first thing that came to mind was Terminator... hehe
PS. Also, they already have prototype arms created... they said the major problem now is packing a good power source into the suit without making it too big...
