4th Infantry Division

4th Infantry Division Insignia

The 4th Infantry Division’s nickname, “Ivy” Division, comes from the design of its shoulder patch, four green ivy leaves joined at the stem and opening at the four corners. Ivy leaves are symbolic of tenacity and fidelity, and are the basis of the division motto, “Steadfast and Loyal.” The word ivy is a play on the Roman numeral four, IV.

The 4th Infantry Division has participated in World War I, World War II, Vietnam, Operation Iraqi Freedom/New Dawn and Operation Enduring Freedom.

In November 2002, the 4th Infantry Division assumed the division ready brigade mission and by January 2003, received orders to form a task force in support of Operation Iraqi Freedom, or OIF. The division began deploying in March 2003. Following a successful 12-month deployment, the division returned home to Fort Hood, Texas.

Shortly after its redeployment, the 4th Infantry Division again received orders to deploy in support of Operation Iraqi Freedom 2005-2007, to serve as the Multi-National Division Baghdad Headquarters, departing in November 2005 and returning in November 2006.

In January 2007, the 4th Infantry Division was called on again to serve as the Multi-National Division Baghdad (MND-B) Headquarters for OIF 07-09. In the succeeding months, the Soldiers of Ironhorse Division trained and prepared for 15 months of combat.

By December 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 July 2009, upon returning from deployment in support of Operation Iraqi Freedom, the 4th Infantry Division was re-stationed to Fort Carson, Colo., from Fort Hood, Texas.

In October 2010, the Ivy Division deployed to Iraq again in support of Operation New Dawn and served as the command for MND-North. Throughout operations in Iraq, 4th Infantry Division Soldiers served with pride and distinction, earning five campaign streamers.

With each of the brigades from the division serving in Afghanistan in support of Operation Enduring Freedom since May 2009, Ivy Soldiers continue to add to the proud history of the 4th Infantry Division.

Today the 4th Infantry Division stands ready to bring the full spectrum of combat power to meet the nation’s call once again.
