Official U.S. Army records place CH-47 Chinook helicopters in the 2003 Iraq War from the invasion phase onward. The Department of the Army Historical Summary for fiscal year 2003 includes 101st Airborne Division crew members preparing to board a CH-47 before flying into Iraq in March 2003, while the same section describes the 101st Airborne Division following the 3rd Infantry Division into Iraq to clear resistance and secure corps lines of communication.
Later Iraq records show the type in continued heavy-lift use and under combat threat. A U.S. Army aircraft-survivability article says a CH-47 was lost to an enemy missile in November 2003, prompting acceleration of missile-warning and countermeasure equipment for helicopters in Iraq and Afghanistan; an American Forces Press Service story archived by DVIDS identifies the aircraft as a CH-47 Chinook shot down in Fallujah, Iraq, on November 2. The National Museum of the U.S. Air Force records an April 16, 2004 Operation Iraqi Freedom rescue mission for a five-person U.S. Army CH-47 crew after a crash near Kharbut, Iraq. DVIDS reporting from Taji in August 2008 documents Company B, 2nd Battalion, 4th Aviation Regiment, Combat Aviation Brigade, 4th Infantry Division using CH-47F Chinooks for logistics missions across Iraq.

Timeline
The first dated source-backed Iraq appearance in this record is March 2003, when 101st Airborne Division CH-47 crews prepared to fly into Iraq during the opening campaign. In November 2003, an enemy missile loss of a CH-47 became a cited driver for a broader Army survivability-equipment effort.
On April 16, 2004, a U.S. Army CH-47 crashed in a sandstorm near Kharbut, Iraq; Air Force HH-60G Pave Hawk crews launched under Operation Iraqi Freedom and recovered the five-person crew. By August 2008, CH-47F Improved Cargo Helicopter crews from the 4th Infantry Division's Combat Aviation Brigade were flying logistics missions from Taji, with DVIDS describing cargo drops across the Iraq theater and resupply missions southeast of Baghdad.

Operational role
The sourced Iraq record supports the Chinook as a U.S. and coalition mobility-and-logistics aircraft rather than a strike platform. The March 2003 Army historical record connects CH-47 crews with the 101st Airborne Division's movement into Iraq. The 2008 DVIDS account describes the CH-47F mission as moving people and cargo, resupplying forward and contingency operating bases, and supporting ground forces throughout Iraq.
The loss and rescue records show the same aircraft family operating in hazardous theater conditions. The November 2003 missile-loss references tie CH-47 operations to the enemy air-defense threat around Fallujah and to the survivability upgrades that followed, and the April 2004 Kharbut crash record documents a CH-47 crew recovered during Operation Iraqi Freedom after a sandstorm crash and subsequent surface-to-air missile attacks against the rescue formation.
