I'd take a pistol over this pile of metal any day. Note the umbilical cord running off to a separate power source. Incredibly not practical.
wow guess you did not get to the part where they are having batteries and armored skeletons
Could you imagine a mini-gun or a .50 on one arm with an ammo backpack and an anti-tank/armor weapon on the other arm? Then having a network of future predator drones buzzing above protecting his airspace and feeding him targeting information.
