In January, Vanity Fair published an article on fighting in Afghanistan's Korengal Valley. To my mind, it buttresses another remarkable article on U.S. troops in that area by NYT Magazine contributing writer Elizabeth Rubin -- Battle Company is Out There, which I blogged as The Prozac War in the Korengal Valley.

Some excerpts:

The Korengal is widely considered to be the most dangerous valley in northeastern Afghanistan, and Second Platoon is considered the tip of the spear for the American forces there. Nearly one-fifth of all combat in Afghanistan occurs in this valley, and nearly three-quarters of all the bombs dropped by nato forces in Afghanistan are dropped in the surrounding area. The fighting is on foot and it is deadly, and the zone of American control moves hilltop by hilltop, ridge by ridge, a hundred yards at a time. There is literally no safe place in the Korengal Valley. Men have been shot while asleep in their barracks tents.

Second Platoon is one of four in Battle Company, which covers the Korengal as part of the Second Battalion of the 503rd Infantry Regiment (airborne). The only soldiers to have been deployed more times since the September 11 attacks are from the 10th Mountain Division, which handed the Korengal over last June. (Tenth Mountain had been slated to go home three months earlier, but its tour was extended while some of its units were already on their way back. They landed in the United States and almost immediately got back on their planes.) When Battle Company took over the Korengal, the entire southern half of the valley was controlled by the Taliban, and American patrols that pushed even a few hundred yards into that area got attacked.

If there was one thing Battle Company knew how to do, though, it was fight. Its previous deployment had been in Afghanistan’s Zabul Province, and things were so bad there that half the company was on psychiatric meds by the time they got home. Korengal looked like it would be even worse. In Zabul, they had been arrayed against relatively inexperienced youths who were paid by Taliban commanders in Pakistan to fight—and die. In the Korengal, on the other hand, the fighting is funded by al-Qaeda cells who oversee extremely well-trained local militias. Battle Company took its first casualty within days, a 19-year-old private named Timothy Vimoto. Vimoto, the son of the brigade’s command sergeant major, was killed by the first volley from a Taliban machine gun positioned around half a mile away. He may well not have even heard the shots. ...

I spent a couple of weeks with Second Platoon and left at the end of June, just before things got bad. The Taliban ambushed a patrol in Aliabad, mortally wounding the platoon medic, Private Juan Restrepo, and then hammered a column of Humvees that tore out of the kop to try to save him. Rounds rattled off the armor plating of the vehicles, and rocket-propelled grenades plowed into the hillsides around them. One day in July, Captain Daniel Kearney, the 27-year-old commanding officer of Battle Company, counted 13 firefights in a 24-hour period.  ...

The Korengal's strategic value:

Dave is a counter-insurgency specialist who spends his time at remote outposts, advising and trying to learn. He wears his hair longer than most soldiers, a blond tangle that after two weeks at Restrepo seems impressively styled with dirt. I ask him why the Korengal is so important.

“It’s important because of accessibility to Pakistan,” he says. “Ultimately, everything is going to Kabul. The Korengal is keeping the Pech River Valley safe, the Pech is keeping Kunar Province stable, and hence what we are hoping is all that takes the pressure off Kabul.”

While we are talking, some rounds come in, snapping over our heads and continuing on up the valley. They were aimed at a soldier who had exposed himself above a hesco. He drops back down, but otherwise, the men hardly seem to notice.

“The enemy doesn’t have to be good,” Dave adds. “They just have to be lucky from time to time.”

Rules of Engagement

The Korengal is so desperately fought over because it is the first leg of a former mujahideen smuggling route that was used to bring in men and weapons from Pakistan during the 1980s. From the Korengal, the mujahideen were able to push west along the high ridges of the Hindu Kush to attack Soviet positions as far away as Kabul. It was called the Nuristan-Kunar corridor, and American military planners fear that al-Qaeda is trying to revive it. If the Americans simply seal off the valley and go around, Taliban and al-Qaeda fighters currently hiding near the Pakistani towns of Dir and Chitral could use the Korengal as a base of operations to strike deep into eastern Afghanistan. Osama bin Laden is rumored to be in the Chitral area, as are his second in command, Ayman Al-Zawahiri, and a clutch of other foreign fighters. While thousands of poorly trained Taliban recruits martyr themselves in southern Afghanistan, bin Laden’s most highly trained fighters ready themselves for the next war, which will happen in the East.

On avoiding harm to civilians

The American rules of engagement generally forbid soldiers to target a house unless someone is shooting from it, and discourage them from targeting anything if civilians are nearby. They can shoot people who are shooting at them and they can shoot people who are carrying a weapon or a handheld radio. The Taliban know this and leave weapons hidden in the hills. When they want to launch an attack they just walk out to their firing positions and pick up their weapons. Following a late-afternoon firefight, they can easily be home for dinner.

The reason for all this caution—other than the obvious moral issues—is that killing civilians simply makes the war harder. With their superior weapons, the U.S. military can kill insurgents all day long, but the only possibility of a long-term victory lies in the civilian population’s denying aid and refuge to the insurgents. The Russian military, which invaded this country in 1979, most emphatically did not understand this. They came in with a massive, heavily armored force, moved about in huge convoys, and bombed everything that moved. It was a textbook demonstration of exactly how not to fight an insurgency. More than one million people died—7 percent of the pre-war civilian population—and a truly popular uprising eventually drove the Russians out.

American forces are far more sensitive to humanitarian concerns than the Russians were—and far more welcomed—but they still make awful mistakes. In June, jumpy American soldiers in Korengal shot into a truck full of young men who had refused to stop at a local checkpoint, killing several. The soldiers said they thought they were about to be attacked; the survivors said they had been confused about what to do. Both sides were probably telling the truth. ...

Whatever the truth of that particular incident, the Taliban have certainly learned the value of American mistakes. Around the same time as the checkpoint shooting, coalition air strikes killed seven Afghan children at a mosque compound in the southeastern part of the country. Reaction was predictably outraged, but almost lost in the outcry was the testimony of survivors. They allegedly told coalition forces that before the air strike al-Qaeda fighters in the area—who undoubtedly knew they were going to be bombed—had beaten the children to prevent them from leaving.

“We had surveillance on the compound all day,” a nato spokesman explained. “We saw no indication there were children inside.”
