The United States is expected to send 100 Special Forces to Iraq, including green berets, navy seals and army rangers deployed to Iraqi brigade across the country, reports CNN.
A formal announcement from President Obama is expected later today.
The Special Forces are expected to be train Iraqi forces to resist ISIS forces which are attempting to take over the country, as well as gathering intelligence information on the whereabouts and bases of ISIS.
The expected announcement comes as the US had previously said there would not be any US troops involved in combat on the ground.
Yesterday the Iraqi government formally requested the US to launch air strikes against ISIS fighters, who have seized several key cities across Iraq.
On Monday, the UK ruled out military intervention in Iraq at present. The British Foreign Secretary, William Hague, instead said the UK would provide assistance "where appropriate and possible [including] counter-terrorism expertise".
