As it draws down troops in Afghanistan, the United States plans to rely heavily on its special forces, gambling the elite troops can serve as a firewall to prevent the Taliban seizing back power, experts and officials say.
Having backed a major troop buildup when he entered office, President Barack Obama is shifting course, opting for a scaled back military presence built around 9,000 special operations forces focused on training Afghan troops and striking insurgent leaders, officials said.
"It's a natural progression," said one defense official, who spoke on condition of anonymity. "As the mission becomes more focused on training, it makes sense that special forces take on more importance. Training is one of their primary missions. That's what they do."
The approach reflects lowered expectations about what can be accomplished after ten years of war and carries an array of risks, analysts and former officials said.
"It's a policy calculation that these (conventional) troops won't be needed. I would bet there would be some challenges," said Jeffrey Dressler, an analyst at the Institute for the Study of War.
Obama's initial strategy was to knock back the insurgency in strategic areas in the south and east, gaining the upper hand on the battlefield to pave the way for handing over security to the Afghans and possible peace talks.
But while the Taliban lost ground in the south, Nato-led forces have yet to roll back the insurgents in the east and the war is still widely seen as a stalemate.
