Having played a little with micro-drones as a hobbyist, the ability to have an "eye in the sky" is amazing. Just today, we got a little turned around on a hike -- in less than a minute I was able to see our location from above and which direction to bushwhack a shortcut back to the main trail. I can see how this would be invaluable in a "strategic" situation. Even the tiny ones are noisy and give away their position immediately. The effective range is relatively short, so you know if there's a drone, the operator is nearby. Weather is a limiting factor -- winds will tax the battery, and rain or wet snow will effectively disable them. I wonder what counter-methods will be used against drones in the field. Really accurate markspeople? Portable EMPs? From what I've read, around airports etc they've been experimenting with enforcing no-fly zones with birds of prey!
