"Israeli soldiers have been shaken by the fighters’ skill and commitment, describing them as an army, not a rabble. “Even I have been surprised at the tenacity of these groups fighting in the villages,” Timur Goksel, who served with UN peacekeepers in southern Lebanon from 1979 to 2003, said. “They have fought far beyond my expectations and they haven’t even committed all their fully experienced troops yet.” " London Times
I hear that the Israelis have been engaged so far with "village reserves," and that they have not yet met the standing forces of HA. This echeloning of categories of forces sounds a lot like the Viet Minh/NVA/VC politico-military set up. Other revolutionary armies?
This is not guerrilla war. Forget that. This is positional warfare waged using field fortifications as the base and pivot so that a heavier force advancing into the "grid" of the defense can be engaged and defeated by attrition. So far, they are doing quite a job. A force in the process of evolution is what I would call HA.
Don’t get too worked up about how old the equipment is or who built what. If it kills, it kills, and the quality of the fortification project speaks for itself.
