“War always changes. Our enemies learn and adapt, and we must do the same or lose. But today, war is changing faster and on a larger scale than at any time in the last 350 years. Not only are we facing rapid change in how war is fought, we are facing radical changes in who fights and what they are fighting for. All over the world, state militaries find themselves fighting non-state opponents. This kind of war, which we call Fourth Generation war, or 4GW, is a very difficult challenge.”
