Israeli tanks have been struck by huge roadside bombs planted in expectation that Israeli armor would roll across the border, said one tank lieutenant, who in keeping with military policy would only give his first name, Ohad.

At least two soldiers from his unit have been wounded by snipers who are accurate at 600 yards. The Hezbollah fighters “are not just farmers who have been given weapons to fire,” he said. “They are persistent and well trained.”

Another tank company commander, a captain who gave his name as Edan, said that about 20 percent of the missiles that have hit Israeli tanks penetrated the Merkava armor or otherwise caused causalities.

Col. Mordechai Kahane, the commander of the Golani brigade’s Egoz unit, first set up to fight Hezbollah, told the Israeli newspaper Yediot Aharonot of one of the worst early days, when his unit went into Marun al Ras in daylight, and lost a senior officer and a number of men.

“Hezbollah put us to sleep” building up its fortifications, he said. “There’s no certainty that we knew that we were going to encounter what it is that we ultimately encountered. We said, ‘There is going to be a bunker here, a cave there,’ but the thoroughness surprised us all. A Hezbollah weapons storeroom is not just a natural cave. It’s a pit with concrete, ladders, emergency openings, escape routes. We didn’t know it was that well organized.”

General Kuperwasser, too, respects Hezbollah’s ability “to well prepare the battlefield,” but says, “We’re making progress and killing a lot of them, and more of them are giving up in battle now and becoming prisoners, which is a very important sign.”
