Direct proof of use
The Cougar 4x4 MRAP is directly documented in the 2003 Iraq War through manufacturer service-history material and U.S. military imagery and reporting. General Dynamics Land Systems describes the Cougar 4x4 as a U.S. Marine Corps combat-engineer workhorse in Iraq since 2004 and as a troop transport in Iraq and Afghanistan that survived repeated IED and landmine attacks.
DVIDS reporting from Al Asad Air Base in June 2009 identifies a Cougar mine-resistant ambush-protected vehicle from Marine Wing Support Squadron 271 during route-clearance training. The same story says the MWSS-271 route-clearance team was preparing to operate heavy armored vehicles while searching for roadside bombs along streets and highways in Iraq's Al Anbar Province.

Timeline
The manufacturer-backed service record places the Cougar 4x4 in Marine combat-engineer use in Iraq from 2004, during the occupation and insurgency phase of the war. The public sources used here do not identify the first individual Cougar mission in Iraq, but they do support sustained Marine Corps use after the vehicle entered service.
By June 2009, DVIDS placed a Cougar MRAP with MWSS-271 at Al Asad Air Base. The Marines were training for route-clearance work in Al Anbar Province, including detection of simulated roadside bombs and preparation to take over supply-route security from the U.S. Army's 937th Engineer Company.

Operational role
The sourced Iraq role is protected engineer mobility rather than a weapons engagement. General Dynamics lists the 4x4 configuration for command and control, explosive ordnance disposal, patrol, convoy support, forward observation, reconnaissance, and medevac tasks. In Iraq, DVIDS documents a Marine route-clearance team using Cougar, Husky, and Buffalo vehicles as mission-specific equipment for finding and identifying roadside bombs.
The operator documented in the Iraq sources is the U.S. Marine Corps. DVIDS names Marine Wing Support Squadron 271 and describes a route-clearance mission tied to supply-route safety for American and Iraqi security forces in Al Anbar Province. The available sources do not show Cougar 4x4 transfer to Iraqi forces in this entry or identify a specific combat engagement involving the vehicle.
Within the catalog role model, the Cougar 4x4's Iraq use fits protected mobility and force protection. Its documented value in the sources is moving combat engineers and route-clearance teams through IED-threat roads while supporting logistics, patrol, and convoy movement.
