The US Army Research, Development and Engineering Command (RDECOM) has officially set a timeframe to design, engineer and have a contract in place for full field testing of an Iron Man-like suit in 4-years (2017)...
-check out the video of the design concept below:
RDECOM wants TALOS (Tactical Assault Light Operator Suit) 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, and fire-retardant capability. The Army also wants the suit to "store and release energy to prevent injuries and increase performance." The suit will have integrated communications, body and external sensors, and a heads-up display that will give battle information graphics in real time along with night vision. Another feature for the suit is an optional attachable exoskeleton that will provide with hydraulic mechanisms to improve both strength and speed.
