The headquarters unit at Fort Riley will deploy as part of the upcoming transition of authority in Iraq.

According to the Army, about 500 Soldiers from the 1st Inf. Div.’s Headquarters and Headquarters Battalion will deploy to the Central Command area of responsibility in late October.

Of those 500, about 200 will deploy to Baghdad and Irbil, Iraq, as part of the 475 troops President Barack Obama authorized Sept. 10 to deploy to Iraq as part of the nation’s strategy to degrade and destroy ISIL. The troops will advise and assist the Iraqi Security Forces to help them go on the offense against ISIL and conduct intelligence, surveillance and reconnaissance flights. This will also increase the United States’ capacity to target ISIL and coordinate the activities of the U.S. military across Iraq.

The Big Red One Soldiers will replace service members who have been in Iraq since June. These forces provide a similarly sized headquarters staff to oversee the expanded range of activities that these U.S. personnel in Iraq were assigned and expand the headquarters of the Joint Forces Land Component Command, which has operational control over activities in Iraq reporting to U.S. Central Command.

The 1st Inf. Div. Soldiers will begin to deploy in October and are preparing for a one-year mission.
