The US forces are expected to land at the Qayyarah air field, about 40km south of Mosul, one of the bases from which the Iraqis plan to attack Daesh forces in their last remaining urban stronghold.
Iraqi military expert Ahmad Akm-Sharifi told Sputnik that the US forces will provide aerial assistance to Iraq government forces in their assault on Mosul.
"As far as we are aware, the US forces in Iraq are carrying out an air operation, to support the Iraqi army from the air. That has been agreed. There won't be any (US) ground operation in Mosul," Akm-Sharifi said.
In recent weeks, Iraqi forces have continued their advance on Mosul, which was overrun by the terrorist group in the summer of 2014 and is the largest city still under terrorist control.
"In reality, regarding ground operations, the forces of the Iraqi army will be enough to combat Daesh. The Iraqi government and army have agreed on an action plan to combat Daesh with their own forces, and the US is aware of that."
"But we need support from the air, including air power that our armed forces don't have," Akm-Sharifi explained.
After retaking Tikrik in March 2015 and Ramadi in December 2015, Iraqi security forces and allied militia have made sustained advances against the terrorist group in recent months.
