In the months building up to the March 2003 invasion of Iraq, two battalions of the 1st Armored Division's 3rd Brigade were deployed to support Operation Iraqi Freedom. The 2–70 Armor and 1–41 Infantry battalion task forces augmented the 82nd Airborne Division, the 3rd Infantry Division, and the 101st Airborne Division throughout the campaign to oust Iraqi dictator Saddam Hussein. These units spearheaded the U.S. assaults in As Samawah and Karbala and later occupied the southern area of Baghdad. The 1st Battalion, 13th Armor followed shortly behind towards the end of March 2003.
