The Defense Department is expected to propose that the United States send ground combat forces into northern Syria for the first time, expand the assault on ISIS, CNN's Barbara Starr reports.
"It's possible that you may see conventional forces hit the ground in Syria for some period of time," an unnamed defense official told CNN.
But the official emphasized that any decision is ultimately up to President Donald Trump, who has ordered his defense secretary to come up with a proposal to combat ISIS before the end of the month.
The move would significantly alter US military operations in Syria if approved and could put troops on the ground within weeks.
Until now, only small teams made up largely of Special Operations forces have operated in Syria, providing training and assistance to anti-ISIS opposition groups on the ground.
Conventional units operate in larger numbers and would require a more significant footprint of security protection both on the ground and in the air.
US officials are characterizing the concept of deploying ground troops as a point of discussion, stopping short of saying it's a formal proposal.
