Direct proof of use
Lockheed Martin directly tied the M299 launcher to Iraq combat use in a 2005 AH-64D Apache Longbow release. The company said it supplied the M299 launcher to the U.S. Army for Apache aircraft and that Apache had carried and fired HELLFIRE II and Longbow HELLFIRE missiles in Iraq.
The same release described the M299 as a combat-proven all-digital launcher integrated with the AH-64D. A Defense Security Cooperation Agency notice later described the M299 Longbow Hellfire Launcher as the quad-rail launcher designed for the AH-64D Apache Longbow and able to carry and launch AGM-114 missiles.

Timeline
The available public record does not isolate a first M299 launcher firing date in Iraq. It does show the supporting chain: AH-64D Longbow Apaches were in the combat theater during the first year of Operation Iraqi Freedom, the M299 was the Army Apache launcher for Hellfire-class missiles, and later official Iraq media records show Apache Hellfire carriage and firing during the same conflict.
DOT&E reported in its FY2004 annual report that the Army deployed 50 AH-64A Apaches and 128 AH-64D Longbow Apaches to Afghanistan and Iraq during the previous year, where both types conducted combat missions in harsh desert conditions. In July 2007, a DVIDS image from Baghdad showed an Apache prepared to head into battle armed with AGM-114K2A and AGM-114N Hellfire missiles, and in March 2008 a DVIDS video entry from Iraq described Apaches engaging an IED with a Hellfire missile.

Operational role
In Iraq, the M299's documented role was not as a standalone weapon but as the reusable launcher and aircraft interface for Apache-fired Hellfire missiles. The launcher carried multiple AGM-114 missiles, provided the electrical and data interface between the helicopter and missile, and allowed the Apache crew to employ HELLFIRE II and Longbow HELLFIRE weapons against ground targets.
The sourced record places the M299 on the United States and coalition side through U.S. Army Apache operations. It supports fire-support and anti-armor categorization because the launcher enabled Apache Hellfire employment, while the public sources reviewed here do not document Iraqi government or insurgent use of the M299.
