The 9K52 Luna-M appears in the 2003 Iraq War through captured Iraqi FROG-7 rockets and launch trucks documented during Operation Iraqi Freedom. A U.S. Marine Corps History Division account published a Defense Imagery photograph of captured Iraqi FROG-7 surface-to-surface artillery rockets resting on Republican Guard launch trucks along Highway 8 near ad-Diwaniyah.
The underlying public-domain Marine Corps image record identifies the same 24 April 2003 scene as two captured Iraqi FROG-7 rockets on Republican Guard launch trucks near Ad Diwaniya. A separate Marine Corps photograph dated 11 April 2003 identifies an Iraqi ZIL-135 FROG-7 transporter-erector-launcher captured by U.S. Marines during Operation Iraqi Freedom.

Timeline
Postwar missile reporting helps explain why FROG-7 systems were still present when coalition forces entered Iraq in 2003. The Iraq missile chronology published by the Nuclear Threat Initiative, citing the Iraq Survey Group's comprehensive report, says Iraq sought after 2000 or 2001 to extend the shelf life of solid-propellant FROG-7 and Ababil-50 rockets.
The dated photographic record then places captured Iraqi FROG-7 equipment in the invasion campaign itself: an Iraqi ZIL-135 FROG-7 TEL photographed on 11 April 2003, followed by the 24 April 2003 Republican Guard launch-truck image near Ad Diwaniya.

Narrative
The supported 2003 Iraq War role is captured or abandoned Iraqi theater rocket artillery rather than a documented firing record. The cited sources identify the systems as Iraqi FROG-7 / Luna-M equipment, tie at least two launch trucks to Republican Guard forces on Highway 8, and place the captures inside Operation Iraqi Freedom.
This evidence separates fielding from confirmed launch use. It supports Iraqi government and security forces as the side associated with the weapon in the conflict, while the available sources for this detail page do not establish a specific 2003 FROG-7 launch, target, casualty event, or impact location.
