The 4th Infantry Division has participated in five combat tours including World War I, World War II, Vietnam, Operation Iraqi Freedom (OIF), and most recently Operation New Dawn. In November 2002, the 4th Infantry Division assumed the Division Ready Brigade mission and by January of 2003, received orders to form a task force in support of Operation Iraqi Freedom. The Division began deploying in March of 2003. In March of 2004, the Division returned from Iraq. Following a successful 12-month deployment, the 4th Infantry Division received orders for deployment to Operation Iraqi Freedom 05-07 to serve as the Multi National Division Baghdad Headquarters, departing Fort Hood, Texas in November 2005 and returning once again in November 2006.
In January 2007, the 4th Infantry Division was called again by our nation to serve as the Multi National Division Baghdad Headquarters for OIF 07-09. In the succeeding months, the Soldiers of Ironhorse Division trained and prepared for 15 months of combat. By December of 2007, the Division assumed the battle-space of Multi-National Division Baghdad for a second time. The Ironhorse Division met Army strategic objectives as MND-B by setting the stage for strategic decisions to be made by the president of the United States and the prime minister of Iraq. The Steadfast and Loyal Soldiers of the Division achieved the lowest levels of attacks in the history of OIF, and the highest level of reconstruction and capacity building ever in Baghdad Province.
In August 2009, the 4th Infantry Division moved from Fort Hood, Texas to Fort Carson. In the months following, the division trained in preparation for a 12-month deployment in October 2010 in support of Operation New Dawn. As the headquarters for the entire northern portion of Iraq, the Soldiers of the United States Division-North made history as they trained the Iraqi security elements and transitioned the remaining responsibility of the region back to the people of Iraq and further established a foundation for an enduring partnership for the future. The 4th Infantry Division has accomplished much throughout its rich history; however, this division will always remember and honor all those Soldiers who paid the ultimate sacrifice during combat operations. The Ivy Division stands ready to bring the full spectrum of combat power to meet our Nation's call once again.
