On 5 April 2003, 2nd Squadron was deployed again to the Gulf for Operation Iraqi Freedom. The rest of the regiment arrived in May and operated in eastern Baghdad. The troopers worked to improve the peoples' lives, and provided security to infrastructure sites such as power stations, telephone stations, fuel stations, schools, and hospitals. The 2nd Armored Cavalry also took direct action in hundreds of raids to disrupt the activities of the Fedayeen Saddam militia. The regiment also trained several companies of the Iraqi Civil Defense Corps (ICDC) to assist their operations. On 19 August 2003, a VBIED detonated near a UN compound and a spinal cord clinic causing consternation and much damage. Elements of the 2nd Cavalry rushed to secure the area, and saved the lives of 125 UN workers.
