An interesting article on the technology that sent Zarqawi to the hereafter.
I recall reading an article by a former Soviet general a few months ago, in which he said that the revolution in information affects war-waging more than entry into the nuclear age. Company-level officers now act on more information than brigade commanders formerly had, and it goes directly to them in realtime, when in past you had to fly a photo recon mission, develop the film, analyse it, report on that, etc. As this article points out, it affects air-ground war, too. Instead of missions being planned days in advance, fighters can be kept aloft and sent to strike, or recon, whatever pops up. Essentially, a war in 2006 is in many ways enormously different from one fought in 1990 or so.
Col. North remarked to me that it affects even supply matters. If you need a part, you punch it into a laptop. A database tells you the nearest location stocking that part. It's then delivered the next day, usually by FedEx (hey, the civilian sector built up the best and fastest delivery mechanism). I assume they don't do tank turbines, but then they might just.
