The camp was captured by the Division Artillery (DIVARTY) of the 4th Infantry Division. The base was then referred to as Forward Operating Base (FOB) Gunner. However, most still simply referred to it as Al Taji or simply Taji . The Base Defense Operations Center and Mayor Cell during this time was operated by the 44th Rear Area Operations Center, Illinois Army National Guard. In early May 2003, Elements of DIVARTY'S 2nd Battalion, 20th Field Artillery and the 1st Battalion, 44th Air Defense Artillery conducted stability and security operations in and around FOB Gunner until March 2004. The 5th Battalion, 3rd Field Artillery Regiment from Fort Sill, Oklahoma, also arrived in early May 2003 to provide security support for the Airfield until they were reassigned to Camp Cedar II (Tallil Air Base) in the late fall of 2003.
