Direct proof of use
The M88 family is directly documented in the 2003 Iraq War through Operation Iraqi Freedom records and later official retrospectives. BAE Systems describes the M88A2 HERCULES as the primary 70-ton recovery system during Operation Iraqi Freedom, and a Marine Corps Systems Command article says Marines used the M88A2 for hoisting, winching, towing, and recovering tanks and other heavy equipment.
Conflict-specific imagery also places a U.S. Marine Corps M88A2 HERCULES with Regimental Combat Team 1 near An Nasiriyah, Iraq, during Operation Iraqi Freedom. The original finding-aid description identifies the vehicle as moving to the front of a convoy north of An Nasiriyah.

Timeline
On March 25, 2003, archival imagery recorded a Marine Corps M88A2 HERCULES with Regimental Combat Team 1 north of An Nasiriyah during Operation Iraqi Freedom, supporting armored movement in the southern campaign.
On April 9, 2003, an M88A2 HERCULES crew from the Marine advance into Baghdad helped bring down Saddam Hussein's statue in Firdos Square. BAE Systems, Marine Corps Systems Command, DVIDS, the Tucson Military Vehicle Museum, and later reporting all identify an M88 or M88A2 as the vehicle used in the event.

Operational role
The M88's Iraq War role was armored recovery and battlefield support rather than direct attack. The M88A2 HERCULES provided a protected tracked recovery vehicle for U.S. armored forces, with the Marine Corps describing its use for tank and heavy-equipment recovery and BAE identifying it as the main 70-ton recovery system used in Operation Iraqi Freedom.
The Firdos Square episode was a symbolic use of the vehicle's pulling and recovery capability. Marine Corps and DVIDS material identify retired Master Gunnery Sgt. Leon C. Lambert as a Marine associated with the M88A2 crew that toppled the statue during the push to Baghdad, while The New Yorker places the M-88 at Firdos Square and describes the event as a globally broadcast image of U.S. control in central Baghdad rather than the end of the war.
