Direct proof of use
Molotov cocktails appear in the 2003 Iraq War record through a 2005 National Defense summary of a 3rd Battalion, 5th Marines scout-sniper platoon lessons-learned report from Operation Phantom Fury in Fallujah. The article says the report listed old-fashioned Molotov cocktails among improvised devices used by Marines in the battle and described their purpose as burning insurgents out of houses.
The documented user in this record is therefore U.S. Marines, specifically the 3rd Battalion, 5th Marines context described by the lessons-learned report. The source supports use during the November 2004 Fallujah fighting; it does not establish a standardized issue munition, a formal supply chain, or wider use across the Iraq theater.

Timeline
Operation Phantom Fury, also known as the Second Battle of Fallujah, began on November 7, 2004, as a U.S.-led operation with Iraqi and British participation to drive insurgent forces out of Fallujah. U.S. Army retrospective coverage places the operation from November 7 to December 23, 2004, and identifies it as the bloodiest battle of the Iraq War.
The Molotov-cocktail evidence is tied to that battle rather than to a precise day inside it. National Defense published its summary on July 1, 2005, after the battle, drawing on a 3rd Battalion, 5th Marines lessons-learned report about urban tactics in Fallujah.

Narrative
The reported Molotov-cocktail use belonged to close urban combat, not long-range fires or conventional incendiary delivery. National Defense framed the item within Marine adaptation to Fallujah house-clearing, where the same article says prewar urban tactics had to be revised under combat conditions.
Official and institutional accounts of the Second Battle of Fallujah describe the setting that made such expedients relevant. Marine Corps University history says 3rd Battalion, 5th Marines advanced through the Jolan District and conducted detailed house-to-house and room-to-room clearing to stop insurgents from rearming or refitting behind them. The same history describes intense squad-level fighting against fortified positions in homes, courtyards, rooms, and hallways.
A Modern War Institute case study identifies 3rd Battalion, 5th Marines as part of Regimental Combat Team 1 and notes that insurgent defenders fortified positions and prepared numerous improvised explosive devices before the coalition assault. Within that environment, the documented Molotov-cocktail role was a short-range incendiary expedient used by Marines during assault and clearing operations in Fallujah.
