Israeli ground troops appear to be operating in southern Lebanon, in force since at least yesterday. According to Stratfor.com, there are "several Israeli brigades. . .between the Lebanese border and the Litani River."
Hezbollah militia forces are reported to be in bunker complexes, "launching rockets." Hopefully this means that the bulk of them are standing and fighting right there near the border, where the Israeli ground troops and big guns can get at them, and this is not just a rear guard covering the flight of the bulk of the terrorists. Standing near the border would be really stupid of them, but we can hope can't we ?
Presumably airmobile/airborne forces are operating somewhere north of the Litani, and also along the paths to the Bekaa Valley, barring escape, or attacking terrorists headed for the Bekaa.
ADDENDUM: For a good discussion of what's going on, and to see a spiffy relief map of the area, check out Wretchard's post "The Lebanese Border" at Belmont Club.
Also, we've been hearing all sorts of bunkum these past several days from the Usual Leftie/All Wet Suspects about the need for "peacekeeping forces" in Lebanon. Uh, beg pardon, but folks, there's a peacekeeping force there already -- the UNIFIL-- the "United Nations Interim Force In Lebanon." Their website is really nifty, and says that the UNIFIL boys and girls are there to "restore international peace and security." Be sure to check out the UNIFIL's really excellent map showing UNIFIL dispositions in the area. As Chester over at Adventures of Chester points out, all the fighting is happening right in the deployment area of the Ghana Battalion peacekeepers. Gotta wonder what kind of "peacekeeping" UNIFIL was up to while the Hezbollah people were crashing the border and grabbing Israeli privates. The "peacekeepers" don't seem to be doing so hot. Wet newspaper might even be better.
