III Armored Corps conflict Iraq War
21st century
In 2001, the corps was composed of the 1st Cavalry Division and the 4th Infantry Division as well as the 3rd Armored Cavalry Regiment and the 13th Corps Support Command. However, with realignment of the US Army and the return of several formations from Europe, the corps took command of the 1st Infantry Division and the 1st Armored Division as well, both of these units having been transferred from V Corps in Germany.
The corps headquarters saw its first combat deployment since the Second World War in 2004, when it deployed to Iraq for Operation Iraqi Freedom. There, III Corps headquarters assumed duties as Headquarters Multi-National Corps – Iraq, relieving V Corps. III Corps served as the administrative command for 2,500 soldiers of the Multi-National Force – Iraq command element, providing operational direction into 2005, when it was returned to Fort Hood, relieved by XVIII Airborne Corps. III Corps has for many years participated in an exchange program which sees a Canadian Army officer appointed as a deputy commanding general.  Notably, Peter Devlin deployed with the corps to Iraq in 2005.
III Corps Artillery was inactivated on 8 September 2006. Henceforth the field artillery brigades, soon to become Fires Brigades, would be assigned to the corps and division headquarters directly.
