The military is one front where disruptive technologies (such as the Internet itself) first appear and "proof of concept" is established. So, it's rather sobering to see how fast plans for deploying robotics in the military are progressing - likely starting with supply couriers.
In my opinion, it's just a matter of time before orchestrated platoons of robotic soldiers become feasible. There are already significant strides being made in environmental sensors and muscle emulation, which will help such units to integrate with human troops while becoming a real pain in the posterior for opposing forces.
Such platoons are scary. They might become sold and leveraged into essentially unassailable mercenary forces, highly efficient killing units, for better or worse. And, there is the approaching singularity where robots (and possibly AIs) will start building robots, too, making easy proliferation another challenge. Hmm, are Terminators and SkyNet on the eventual horizon? Let's hope not!
