Associated Press Writer= NAWA, Afghanistan (AP) â U.S. Marines hiked through searing heat and took fire from small pockets of militants Thursday after landing in this Taliban-controlled southern region of tree-lined fields, mud homes and crisscrossing waterways in the first major operation under President Barack Obama's strategy to stabilize Afghanistan.
Elsewhere, the U.S. military announced that insurgents were believed to have captured an American soldier missing in eastern Afghanistan on Tuesday. The missing soldier was not involved in Operation Khanjar, or "Strike of the Sword," under way in southern Afghanistan.
The southern offensive was launched shortly after 1 a.m. Thursday (4:30 p.m. EDT Wednesday, 2030 GMT), as thousands of Marines poured from helicopters and armored vehicles into Taliban-controlled villages along roughly 20 miles of the Helmand River in Helmand province, the world's largest opium poppy-producing area. The goal is to clear insurgents from the hotly contested region before the nation's Aug. 20 presidential election.
The Marines have not suffered any serious casualties and have seen only a sporadic resistance, said Lt. Abe Sipe, a spokesman for the unit.
"The enemy has chosen to withdraw rather than engage for the most part," Sipe said. "We had a couple of heat casualties, but not deemed serious in nature at this time."
Officials described the offensive as the largest and fastest-moving of the war's new phase and the biggest Marine assault since the one in Fallujah, Iraq, in 2004. It involves nearly 4,000 newly arrived Marines plus 650 Afghan forces. British forces last week led similar, but smaller, missions to clear out insurgents in Helmand and neighboring Kandahar province.
"Where we go we will stay, and where we stay, we will hold, build and work toward transition of all security responsibilities to Afghan forces," Marine Corps Brig. Gen. Larry Nicholson said in a statement.
Pakistan's army said it had moved troops from elsewhere on its side of the Afghan border to the stretch opposite Helmand to try to stop any militants from fleeing the offensive. It gave no more details, but U.S. and Pakistani officials have expressed concern that stepped-up operations in southern Afghanistan could push the insurgents across the border.
Transport helicopters carried hundreds of Marines into the village of Nawa, some 20 miles south of the provincial capital of Lashkar Gah, in a region where no U.S. or other NATO troops have operated in large numbers.
The troops took many insurgents by surprise, dropping behind Taliban lines, said Capt. Drew Schoenmaker, from Greene, N.Y.
"We are kind of forging new ground here. We are going to a place nobody has been before," said Schoenmaker, 31, who commands Bravo Company of the 1st Battalion, 5th Marine Regiment.
Several hundred Marines took positions in a freshly plowed dirt field at 3 a.m. The soft, deep dirt proved challenging for troops weighed down with days' worth of water, food and gear, and many frequently stumbled.
At daybreak the Marines walked along tree lines, and at 6:15 a.m. the company took its first incoming fire, likely from an AK-47 along a tree-line. The next three hours brought repeated bursts of gunfire and volleys of rocket-propelled grenades, sending deep booms across the countryside.
A small force of Afghan soldiers accompanying the Camp Pendleton-based Marines got into several scraps with an insurgent force of about 20 fighters. The fire came from a mud-brick compound, and the Marines, the Afghan soldiers and their British advisers surrounded the compound on the east and the south.
Before the mission, Schoenmaker, the company commander, said he would practice "tactical patience" as a way to avoid civilian casualties â an issue newly arrived Gen. Stanley McChrystal has underscored in recent weeks. Though troops in many similar circumstances have called in airstrikes on such a militant-controlled compound, Schoenmaker did not.
"We made the decision to isolate the compound and not destroy it because we couldn't confirm if civilians were inside," he said. The militants were believed to have escaped out the back.
A Cobra helicopter circling overhead for most of the day fired rockets at a tree line nearby. Other troops walked through fields of corn and past mud-wall homes. Only a handful of villagers dared to venture outside.
Helmand's deadly heat, well over 100 degrees Fahrenheit, proved to be another enemy the Marines had to fight. Because soldiers were on foot, they had to carry all their own water and food. Forward observers and snipers spent the entire day under the cloudless sky.
"It's like when you open up the oven when you're cooking a pizza and you want to see if it's done. You get that blast of hot air. That's how it feels the whole time," said Lance Corp. Charlie Duggan Jr., 21, of Baldwinsville, N.Y.
The Marines trained for months in the heat of the Mojave desert for the deployment, and many appeared happy to be here.
At one point Thursday, some 50 Marines were relaxing in an abandoned and dilapidated mud brick compound, their dusty-brown uniforms stained with perspiration. Suddenly someone spotted an Afghan male who appeared to be watching them from a nearby road.
The Marines quickly threw on their flak jackets and Kevlar helmets.
"It sucks but it's what you've been training for your whole life," Lt. Chris Wilson, 25, of Ramsey, N.J., said with a smile as he held a radio with an eight-foot antenna. Thursday was Wilson's first mission into a combat zone.
Last summer, the 24th Marine Expeditionary Unit took the town of Garmser â about 15 miles south of Schoenmaker's company â and helped provide security for an area U.S. commanders say is now relatively secure.
The U.S. would like to replicate the success in Garmser to the north and south. The strategic setting can help the military slow the opium poppy and heroin trade and interdict fighters coming from Pakistan.
Of immediate need is security for the country's Aug. 20 election.
Southern Afghanistan is a Taliban stronghold but also a region where Afghan President Hamid Karzai is seeking votes from fellow Pashtun tribesmen. Without such a massive Marine assault in this southern section of Helmand, the Afghan government would likely not have been able to set up voting booths to which citizens could safely travel.
The Pentagon is deploying 21,000 additional troops to Afghanistan in time for the elections and expects the total number of U.S. forces there to reach 68,000 by year's end. That is double the number of troops in Afghanistan in 2008 but still half as many as are now in Iraq.
The Taliban, who took control of Afghanistan in 1996 and were ousted from power following a U.S.-led invasion in 2001, have made a violent comeback, wreaking havoc in much of the country's south and east.
Thousands of British forces, fighting under NATO command, have been in Helmand since 2006 with broadly the same strategy, but security has deteriorated. They have encountered stronger resistance than had been expected from Taliban fighters bankrolled by the vast opium and heroin trade.
Reversing the insurgency's momentum has been a key component of the new U.S. strategy, and thousands of additional troops allow commanders to push into and stay in areas where international and Afghan troops had no permanent presence.
In March, Obama unveiled his strategy for Afghanistan, seeking to defeat al-Qaida terrorists there and in Pakistan with a bigger force and a new commander. Taliban and other extremists, including those allied with al-Qaida, routinely cross the two nations' border.
Obama told The Associated Press on Thursday that he will reassess the possible need for additional U.S. troops in Afghanistan after the August elections.
The president said the main U.S. goal is to keep al-Qaida from acquiring a haven from which it can train fighters and launch attacks on the United States or its allies. He said the U.S. and its allies also must build up the Afghan national army and police and enable Pakistan to secure its borders against terrorist movements.
Last year, NATO and Pakistani forces cooperated in a series of complementary operations on the border, but the overall commitment of Islamabad to Washington's aims in Afghanistan has long been questioned. Pakistan has frequently been accused in the past of failing to stop â and sometimes aiding â the movement of insurgents into Afghanistan from its side of the border.
