From FUNKER350: The 1st Infantry Division Headquarters, based out of Fort Riley, Kansas will be the first division headquarters to deploy to Iraq since the withdrawal in 2011, and will consist of about 500 soldiers. They will deploy in late October and will hold positions in Baghdad, Kurdistan, and possibly other areas not currently being declared by the CENTCOM.
Some soldiers will be advisers to Peshmerga and Iraqi Security Forces, while others will provide support and security for future American operations across Iraq. The Big Red One’s 1st Brigade Combat Team is already standing by in Kuwait as part of a regular rotation of forces to the region. However, at this point they have not been tasked with a fighting role in the developing situation.
