William S. Lind names two models for fighting Fourth Generation war: the de-escalation model and the Hama model, based on what Hafez al-Assad did to the Moslem Brotherhood in the Syrian city of Hama — he flattened the place:
We draw one critically important point from Martin van Creveld: you can use either model with some hope of success, but if you fall between the two, you will certainly fail. If you are going to be brutal, it has to be over fast. If you can’t get it over fast, you must de-escalate.
We stress that in fighting 4GW, “less is more.” Try to keep your physical presence small, if possible so small you are invisible. If you can’t do that, then keep your footprint small in time – get in and get out, fast. Finally, if you have to take the least desirable route, invading and occupying another state, you must do everything you can to preserve that state at the same time you are defeating it. As we see in Iraq, if you destroy the state itself, there is a good chance nobody will be able to recreate it.
Getting down more to specifics, we stress that 4GW is above all light infantry war — real light infantry, jaegers, not what the U.S. calls light infantry, which is just line infantry with less equipment. We talk about “Out G-ing the G,” in Hackworth’s phrase. We discuss your most important supporting weapon: cash. We go into how to integrate your men with the local population (American-style “force protection” makes this impossible). We look at how intelligence changes in 4GW (humint is everything, and IPB goes out the window) and how to win the fight at the mental and moral levels.
