Since the emergence of the modern warfare, four “generations of warfare” have been identified. The first generation, or 1GW, emphasizes concentration-of-soldiers. The most famous 1GW was the Napoleonic Wars, where the commander who could throw the most soldiers at the decisive point would in the war. The second generation, or 2GW, emphasizes concentration-of-force. The most famous 2GW was the western front of World War I, where the force that could concentrate the most artillery and explosive power at one point could win the day. Both 1GW and 2GW are made possible by reducing your fog of war, so that you know where your soldiers (1GW) or artillery (2GW) should go.

The third generation, or 3GW, emphasizes maneuver. The most famous 3GW was the German Blitz against France in 1940, where the force that could break through and carry the commander’s intent would win the day. The fourth generation, or 4GW, emphasis networks. The most famous 4GW were the Communist insurgencies in Asia, where the force that could alienate the population from the other side through unconventional means would prevail in the end. Both 3GW and 4GW are made possible by maximizing your enemy’s fog of war, so he is unable to properly command his troops (3GW) or rely on his population (4GW).

The fifth generation of modern warfare, or 5GW, is more speculative. It is assumed that as each generation of modern warfare “goes deeper” into the enemy’s social thinking (from where he concentrates soldiers, to where he prepares for an artillery barrage, to how he springs back from a blitz that seems to come from everywhere, to what he does when faced with insurgents who kill the tax collector), 5GW will go deeper yet. As each higher generation of war looks less like “traditional” war than the generation before it, it has been argued that 5GW will not even appear to be a “war” at all…
