I checked google and found this site, it has some information on real US army robotic enhancements.

" The suit will include shape-memory alloys to enhance soldiers' strength, advanced sensors to improve their awareness, and microphotonic materials to change their appearance"

microphotonic materials? Any one know what they are?

and another artical on that site

"A US Army program to develop high tech applications for soldiers to increase their strength and fighting ability as well as improve survivability"
