KABUL, Afghanistan (AP) - The commander of NATO and U.S. forces in Afghanistan issued an updated directive Wednesday, repeating his predecessor's curbs on use of air power and heavy weapons when civilians are at risk but stressing the right of troops to defend themselves.
The new guidance comes after complaints from troops that rules of battle laid down by former commander Gen. Stanley McChrystal were putting them in danger and handing the advantage to the Taliban.
There had been speculation that Gen. David Petraeus - who took over from McChrystal a month ago - might ease the rules. But Petraeus, like McChrystal, emphasized that protecting the Afghan people was the top priority in the war.
"We must continue - indeed, redouble - our efforts to reduce the loss of innocent civilian life to an absolute minimum," Petraeus wrote in the document released by the NATO command Wednesday. Some sections were not released for security reasons, the command said.
McChrystal stressed the need to reduce civilian casualties as a tool for winning the war - noting that every civilian killed the crossfire created a legion of family members with a grudge against NATO forces and motivation to join the Taliban.
Under this guidance, NATO forces drastically restricted the use of air strikes, which had previously been called in without knowledge of who was inside a building. Troops were also instructed to only fire on people who were actively firing on them.
Though McChrystal's directive did frustrate many soldiers in the field, it also led to a drop in civilian deaths attributed to NATO forces.
Petraeus said nothing in the guidance was meant to hinder the right to self-defense.
"We must employ all assets to ensure our troopers' safety, keeping in mind the importance of protecting the Afghan people as we do," Petraeus wrote.
A spokesman for NATO forces said the directive will help troops understand how to balance the two.
"We also have now an absolutely clear wording and language on the necessary balance between the right of self-defense, the protection of the people, and the assurance of moms and dads back home that their boys and girls absolutely do have the necessary means and measures to achieve mission and success," said NATO spokesman Brig. Gen. Josef Blotz.
The new directive implied that some lower-level commanders had misinterpreted McChrystal's guidance and made rules in their areas more restrictive than needed.
"Subordinate commanders are not authorized to further restrict this guidance without my approval," Petraeus wrote in the document.
Petraeus said that the rules were not aimed at slowing the war, but were essential to victory.
"We must continue to demonstrate our resolve to the enemy," Petraeus writes. "We will do so through our relentless pursuit of the Taliban and others who mean Afghanistan harm, through our compassion for the Afghan people, and through the example we provide to our Afghan partners."
The battle to win over the civilian population is being waged on both sides. The Taliban issued a directive a little over a week ago that calls on its fighters to avoid killing civilians and forbids them from seizing weapons and money.
However, the 69-page booklet also declares that people working for international forces or the Afghan government are "supporters of the infidels" and can be killed.
At least 2,412 Afghan civilians were killed in fighting last year - up 14 percent from 2008, according to the United Nations. The U.N. found that about two-thirds of the civilian deaths were a result of actions initiated by the insurgents, while the percentage of civilian deaths attributed to NATO and Afghan government forces had dropped.
In the days since the release of the code of conduct, insurgents have killed 43 Afghan civilians - most in bomb explosions, NATO said.
The directive comes as the nearly 9-year-old war is becoming increasingly deadly. July was the deadliest month for U.S. forces with 66 troops killed, and June was the deadliest month for the overall NATO force with 103 killed.
New Zealand suffered its first combat death of the war Tuesday during an ambush in one of Afghanistan's most peaceful provinces.
The Taliban claimed responsibility for the attack against a New Zealand military patrol in Bamiyan province, a central area where most of the ethnic Hazara population opposes the insurgents. Two New Zealand soldiers and an Afghan translator were wounded, New Zealand Defense Force Chief Lt. Gen. Jerry Mateparae told reporters in Wellington.
He said the three-vehicle patrol was attacked with a roadside bomb, rocket-propelled grenades and small-arms fire.
Provincial spokesman Abdul Rahman Ahmadi said the attack occurred about 5 p.m. in the Kohmard district of northern Bamiyan. Ahmadi said the insurgents were believed to have infiltrated from nearby Baghlan province, which has seen an increase in Taliban activity in recent weeks.
Insurgent activity has been spreading into areas beyond the militants' longtime bases in the south and east of the country, even as the U.S. and its allies are rushing thousands of reinforcements to try to turn back the Taliban. The focus of U.S. and NATO operations has been in the ethnic Pashtun south.
