Robotic infantry units coming to an Iraq near you
The Special Weapons Observation Remote Reconnaissance Direct Action System" (SWORDS) robots have recently been deployed to Iraq. These remote controlled robots are armed with M249 machine guns, but can also be armed with any standard issue weapon that an American infantry soldier might utilize, such as anti-tank weapons and grenade launchers. (The video above gives an excellent 9 min. overview.)
The ability of a wealthy, technologically advanced nation like the US to field robotic infantry units is the next logical step from what has already been occurring with Air Force ordinance.
There will inevitably come a nasty transition point where one nation fields robotic infantry units while another must field human infantry units. It seems to me that the immediate response would be the quick deployment by the less technologically advancd nation of some form of constrained radius EMP device, such as a pulse bomb, focused wave generator, or even pulse mortar. I suspect knocking out the circuits of such a robot (or collection of robots) would not be difficult, if the much hang-wringing over the complexity of shielding avionics in the 1980s from nuclear blasts is any indication.
