The special operations force would conduct raids, could free hostages held by ISIS, gather intelligence and capture ISIS leaders in both Iraq and Syria.
Some U.S. Special Operations forces currently operate inside Iraq in an advise-and-assist role with Iraqi and Kurdish forces, but have not engaged in unilateral raids, U.S. officials said. The American forces that participated in the October rescue raid in Hawija, Iraq, were accompanying Kurdish forces when they became involved in the fight.
ISIS is also known as ISIL or the Islamic State.
Carter said their operations in Iraq would create "a virtuous cycle of better intelligence, which generates more targets, more raids, and more momentum."
A U.S. official told ABC News that initial planning for the new special operations task called for roughly 200 personnel in Iraq. The official also said it was unclear if that number of personnel would fall under the current authorized cap of 3,550 U.S. troops in Iraq or might lead the White House to authorize a larger number of troops to serve in a training and advise and assist role in Iraq.
General Joseph Dunford, the chairman of the Joint Chiefs of Staff, told the committee today any military recommendations in the war on ISIS are not limited by that troop cap.
"I can assure you that I don't feel at all inhibited about making recommendations that would cause us to grow greater than 3,500, or would I were to believe that would help us to defeat ISIL,” Dunford said.
Much as special operations forces operated against al Qaeda in Iraq during the previous U.S. military in Iraq, “our operations will be intel driven,” said Dunford. "Our assessment is that this force and the operations this force will conduct will provide us additional intelligence that'll make our operations much more effective. And I think that's what the secretary refers to when he talks about the virtuous cycle.”
“The enemy doesn't respect boundaries; neither do we. We are fighting a campaign across Iraq and Syria. So we're going to go where the enemy is and we're going to conduct operations where they most effectually degrade the capabilities of the enemy," Dunford said.
Carter said the force would "also be in a position to conduct unilateral operations into Syria." Over the past year, U.S. special operations forces have already conducted two targeted raids into Syria.
Editor’s Note: ABC News initially reported that the raid that resulted in the death of Master Sergeant Joshua L. Wheeler occurred in September 2015. It occurred in October 2015.
