Direct proof of use
ATACMS use in the 2003 Iraq War is directly documented by Lockheed Martin and Human Rights Watch. Lockheed Martin's 2009 reliability release said ATACMS scored successes in Operation Iraqi Freedom and Operation Enduring Freedom, with about 550 missiles fired across the Global War on Terror. Human Rights Watch's December 2003 report, drawing on U.S. ground-force and Field Artillery reporting, stated that the 3rd Infantry Division, 101st Airborne Division, and 214th Field Artillery Brigade reported using 330 Army Tactical Missile System missiles in Iraq.
Those sources establish U.S. use rather than mere possession or deployment. The available public figures are not identical in scope: Human Rights Watch reported a 2003 Iraq figure for listed Army formations, while Lockheed Martin gave a later combined Operation Iraqi Freedom and Operation Enduring Freedom total.

Timeline
The U.S. Army Center of Military History dates the initial major combat phase of Operation Iraqi Freedom to March-May 2003. During that campaign, U.S. Army formations used MLRS-family fires and ATACMS as part of ground operations. Human Rights Watch reported 330 ATACMS missiles used by the 3rd Infantry Division, 101st Airborne Division, and 214th Field Artillery Brigade, alongside MLRS rockets and SADARM artillery rounds.
Postwar reliability and modernization reporting continued to cite Operation Iraqi Freedom as a major combat-use period for the missile family. Lockheed Martin's 2009 release described ATACMS as combat proven in Operation Iraqi Freedom and Operation Enduring Freedom and tied the system to long-range strike capability in all weather and environments.

Narrative
In the Iraq theater, ATACMS was a U.S. long-range surface-to-surface missile fired from MLRS-family launchers. CSIS describes the missile as a road-mobile, solid-fuel short-range ballistic missile with Block I and Block IA ranges of about 165 km and 300 km, and with warhead options that included high explosive, blast-fragmentation, and submunition payloads.
The documented Iraq role was long-range tactical fires. Human Rights Watch described U.S. ground-launched cluster munitions in the invasion as being used for counter-battery missions and suppression of enemy air-defense missions, and specifically included ATACMS among the reported missile-delivered submunition systems used by U.S. Army formations. Lockheed Martin later framed ATACMS in Operation Iraqi Freedom as part of the system's record of combat-proven long-range strike performance.
The public sources support U.S. use and broad mission categories, but they do not provide a complete public shot-by-shot record in this entry. The record therefore separates the confirmed firing of ATACMS in Operation Iraqi Freedom from more precise claims about individual targets, which are not consistently supported by the sources used here.
