The fact is that it's real. The Pentagon is totally building Iron Man, and the US Army has confirmed this a few times already. In fact, along with robots, it's one of its biggest bets, just like the US Air Force and the US Navy are betting on drones. I wrote about this last year:
While the Army's Iron Man suit—officially called Tactical Assault Light Operator Suit (TALOS)—will not have flying capability, little missiles, or repulsors, the feature list is still extremely impressive.
RDECOM wants TALOS to have ballistic and shock protection—using an armor that will get from flexible soft surface to hard metal solid, capable of repelling ammo when applying an electric current. Oh, and fire-retardant capability. The Army also wants the suit to "store and release energy to prevent injuries and increase performance."
And as if that wasn't impressive enough, the suit will have integrated communications, body and external sensors, and a head-up display that will give battle information graphics in real time along with night vision. It will be more Google Glass than Jarvis in this generation, but you get the idea.
Another feature for the suit is an optional attachable exoskeleton that will provide with hydraulic mechanisms to improve both strength and speed. Like the others, this technology exists already.
