The Marines of 1st MLG were deployed to Iraq in support of Operation Iraqi Freedom on four occasions.

First deployment

The 1st FSSG deployed to Iraq in early 2003 in response to the continual rejection of UN inspectors. In March 2003, 1st FSSG elements joined the 1st Marine Expeditionary Force (I MEF) in the crossing into Iraq. After approximately one month and the fall of Bagdad, the war was declared over. The Marines of 1st FSSG along with the 1st MEF redeployed back into the States over the rest of the summer 2003.

Second deployment

In January 2004, the 1st FSSG deployed to Iraq for a second time – for 14 months to various camps in Iraq to include Camp Taqaddum (Headquarters), Camp Fallujah, Al Asad Air Base, Camp Habbiniyah, and, after the Abu Ghraib scandal, they took over guarding the prison as well. The group was involved with Operation Al Fajr (The Second Battle of Fallujah), the operation to retake the city of Fallujah. The artillery that helped bombard the city were stationed in the 1st FSSG HQ area. They returned to Camp Pendleton in early 2006.

In October 2005, the group was redesignated as 1st Marine Logistics Group in an effort to make the name reflect the mission. The lower subordinate units were reorganized and some renamed.

Third deployment

In February 2007, the Group returned from their third deployment, having served in several locations, including Camp Fallujah, Camp Taqaddum and Al Asad Air Base. The deployment was part of two seven-month assignments, but many Marines stayed for the greater duration of 14 months.^[4]
