ISIS fighters already on the run from more than a thousand Russian air strikes will now also have to contend with American special forces on the ground in Syria.
Moscow revealed it had hit an astonishing 1,623 terrorist targets, including military camps, command points and communication hubs since raids began a month ago.
With ISIS heavily depleted by the relentless bombing, Washington today revealed a number of special operations commandos are about to be sent into Syria.
Around 50 are to be deployed in the country.
But the US maintaining there will be no boots on the ground in Syria White House spokesman Josh Earnest insists the elite fighters will be there to "train, advise and assist".
He said it would be an expansion of the US strategy in Syria.
