US Defence Secretary Ash Carter has committed to deploying additional troops to support Iraqi forces as they continue the fight against ISIS.
The US will send nearly 600 military personnel to Iraq to provide logistics and maintenance support.
American troops will train, advise and assist the Iraqi Security Forces and Kurdish Peshmerga for the upcoming Mosul operation.
Carter said: “The coalition to defeat ISIS continues to achieve results on the battlefield, and I congratulate Iraqi security forces on their recent progress, including the operation to free Sharqat.
"The coalition will continue to increase the pressure on ISIS in Mosul and wherever it seeks refuge in Iraq.”
US troops will collaborate with the Government of Iraq to provide expanded intelligence resources, in order to help disrupt the ISIS terrorist network in Iraq and beyond.
“The US will continue to stay in close contact with our Iraqi partners as efforts to retake Mosul progress, including the role that the international coalition can continue to play in helping the Iraqi Government defeat ISIS.”
The deployment follows President Barack Obama's approval of a request from the Department of Defense to increase the number of US military personnel that will be deployed to Iraq.
White House Press Secretary Josh Earnest said at a press briefing that 'these are military forces that will be deployed to intensify the strategy that is in place to support Iraqi Security Forces as they prepare for an offensive against ISIS'.
