Newsweek has an interesting article about a platoon of IDF reservists patrolling the underground routes used by suicide bombers on their way into Israel: A Shark Hunt In The Night.

Lebanon was a more traditional war for the infantrymen of the Palnat Company. There they shouldered TOW missiles into action against Hizbullah guerrillas. Here they patrol in their sandbagged Nagmashes across a patch of rugged hills, canyons and picturesque Arab villages tucked between the cities of Tulkarm and Nablus in the northern West Bank; in effect, they’re well-armed cops in olive drab. Until last week the area was under Palestinian Authority control; during the intifada, Israeli intelligence says, it became infested by suicide bombers who hopscotched from one village to the next as they wended their way from Nablus’s explosives labs to Tulkarm, a militant hotbed just a short drive from the Israeli cities of Netanya and Hadera. Along dusty tracks given code names such as “Salvador” and “Hawaii,” in villages like Anabta and Beit Lid, Cohen-Topel and his men lay ambushes, set up checkpoints and make predawn raids on suspected militants. Their main mission, says one, is to “put the Palestinians on notice that we are here.”
