X-45 and the Future of Air Warfare

A Boeing Joint Unmanned Combat Air System X-45 aircraft released an inert Global Positioning System-guided bomb at the Naval Air Warfare Center Weapons Division Range at China Lake, Calif. on April 18, 2004.

When this stuff gets going the world is going to change. They work in concert and never risk a operator's life. They drop precision munitions too. These things will be deadly in combat.

The question is if air power will still be relevant on tomorrow's battlefield? I mean in traditional conflicts it will of course, but Iraq seems to be the future to me. After you have beaten the enemies army/ari/naval power to a pulp, you still need to occupy and that is where things get messy. Air power can't help you here.

I don't understand why we have not developed armor for our troops. It is technecally feasible to create an armor suit that empowers the wearer to lift heavy objects etc., while protecting the wearer from battle damage. I suppose cost is the primary factor, but if you could have practically industructible infantry (the main issue would be kenetic energy disapation) what would the "insurgents" do then?
