Even on earth modern warfare is becoming automated, and precise disabling weapons using sound, heat, etc. are being used, not to mention our extensive stockpiles of chemical/biological stuff. If we can develop such precise ways of killing eachother I'm sure ET's would be capable of the same. I imagine they'd use drones or create a very specific pathogen to wipe us all out. Or maybe they'd engineer super mosquitoes that can breed outside of water and survive in freezing temperatures. eek Now that would be a nightmare.
