Strategy Page has a very interesting discussion of how Israel’s military has learned and adapted from its failures in the 2006 Lebanon war:
After the 2006 war Israel realized two things; its military was still superior to Arab forces and its military was not as superior as Israel believed it was. The major Israeli deficiency was communications. What the Arabs, or at least Iran-backed Hezbollah, had done was learned to move faster and more resourcefully than the Israelis expected. What really shocked the Israelis was that although they could spot and track these Hezbollah moves they could not get artillery, aircraft or ground troops moved quickly enough to take out a lot of identified targets before the enemy managed to change position. All the different levels of Israeli headquarters and combat units could actually communicate with each other, but not fast enough to hit a target that had been identified and located but was not staying put long enough for the completion of all the procedures and paperwork required to get the strike order sent to the unit best able to carry it out.
The solution was new technology and procedures. Since 2006 Israel has built a new communications system that is faster and able, according to Israeli claims, to hit a lot more targets than the 2006 era forces could manage. Much of the solution had nothing to do with radical new hardware but to simply standardizing the procedures everyone had long used to call for fire, or to deliver it. Now commanders at all levels can see the same data and call for and receive fire support quickly. Thus when a target is identified the bombs, shells or ground attack follows quickly. Everyone was shown how easy, and damaging it was to underestimate the enemy. In training exercises the “enemy” is controlled by Israeli troops with ordered to be imaginative and try real hard to not get spotted and hit. It’s been amazing what these “enemy” troops come up, and necessary to keep this secret so that the real enemy does not find out.
While we withdraw from the world in the face of external threats, downsizing our military, slow-walking R&D and firing thousands of experienced NCOs and mid-level officers, other countries are learning and adapting. Not all of those countries are our allies.
