Direct proof of use
The M230 is directly documented in the 2003 Iraq War through official DVIDS reporting from northern Iraq. A July 2008 DVIDS story identifies the 30 mm M230 chain gun as the AH-64D Apache Longbow's main fixed armament and describes Company D, 1st Attack Reconnaissance Battalion, 1st Aviation Regiment armament crews loading 30 mm ammunition, checking the weapon system, lowering rounds to the gun, and chambering the first round before Apache missions.
A linked DVIDS image record places the same weapon at Tikrit on May 26, 2008, where an AH-64D armament systems repairer adjusted a 30 mm M230 chain gun while 1-1 ARB air and ground crews sustained air operations in support of Task Force Iron in northern Iraq.

Timeline
On May 26, 2008, DVIDS documented an AH-64D Apache Longbow armament systems repairer adjusting a 30 mm M230 chain gun at Tikrit, Iraq. The caption tied the aircraft and its ground crews to Combat Aviation Brigade, 1st Infantry Division air operations supporting Task Force Iron in northern Iraq.
On July 4, 2008, DVIDS published a detailed story from Iraq describing the 1-1 ARB armament section's work on AH-64D Apache Longbows. The story explained how crews loaded 30 mm rounds for the M230, checked for gaps, chambered the first round, and kept the aircraft mission-capable for Apache operations in northern Iraq.
By May 2011, another DVIDS report placed 8-229th Attack Reconnaissance Battalion Apaches at Camp Taji during Operation New Dawn. That report described the AH-64 Apache as armed with a 30 mm M230 chain gun and assigned to reconnaissance, convoy protection, and air support for ground units in Iraq.

Operational role
The sourced Iraq record places the M230 on the United States and coalition side of the war as the fixed gun armament of AH-64D Apache Longbow attack helicopters. The clearest unit-level evidence comes from Company D, 1-1 ARB, supporting Combat Aviation Brigade, 1st Infantry Division operations in northern Iraq in 2008.
The gun's documented role was attack-helicopter fire support rather than transfer to Iraqi forces. DVIDS reporting connects the Apache force to sustained air operations, convoy escort demand from ground troops, reconnaissance, convoy protection, and air support for ground units. Within that mission set, the M230 was loaded, inspected, adjusted, and readied by armament crews as the Apache's 30 mm gun system.
The available official sources document presence, preparation, and operational employment context rather than a complete record of every M230 firing event or every Apache unit in Iraq. The catalog claim is therefore limited to U.S. Apache-mounted M230 fielding and fire-support use in the Iraq theater.
