"The wars of the future will not be fought on the battlefield or at sea. They will be fought in space, or possibly on top of a very tall mountain. In either case, most of the actual fighting will be done by small robots. And as you go forth today remember always your duty is clear: To build and maintain those robots."
-The Simpsons
I think of it this way instead of facing groups of trigger happy, pimple faced kids they will be facing cold unfeeling robots bend on conquest. I think this should scare the $h!t out of our enemies! Remember
deterrence anyone? When you and your Mujaheddin friends blow up that tank your not killing any Americans you are just blowing up a piece of hardware. No matter what you do short of sending a ballistic missile at the US will you kill an American serviceman. All the 'bots you destroy are just rebuilt at some factory (perhaps by other robots). Think of what the CNN worm will say every day:
27 Mk 8 battle chassis were destroyed in separate attacks in occupied Siberia today...
Would you care?
A robot under fire can just sit there if it wants! It has no sense of self preservation. Just sit there and locate who is doing the shooting, it can just see
oh this is a situation where there are non-combatants near by, don't shoot and just take the hit.
Just think about it... no more flag draped coffins just boxes of metal and silicon marked
battle scrap.
