Direct proof of use
Navistar Defense reported on July 8, 2008 that U.S. Army TACOM Life Cycle Management Command had awarded seven contracts worth about $125 million to support International MaxxPro MRAP vehicles in Iraq. The release described replacement parts and field support for vehicles operating in theater during hazardous missions.
A DVIDS report from Victory Base Complex in March 2009 separately recorded Mine Resistant Armor Protected MaxxPro driver training for the 180th Horizontal Construction Company after the unit arrived at Camp Stryker under the 54th Engineer Battalion. Together, the sources place the MaxxPro family in U.S. service in Iraq and show both operational sustainment and driver training inside the conflict theater.

Timeline
The direct public record begins during the 2007-2008 MRAP fielding surge. Defense Industry Daily, summarizing Pentagon contract notices, reported September 2007 field-service support for MRAP Category I MaxxPro vehicles in Iraq at Camp Liberty, followed by later MaxxPro orders and sustainment actions.
By mid-2008, Navistar described a larger parts-and-support package for MaxxPro vehicles in Iraq, including replacement parts, field-service representatives, and theater distribution. In March 2009, DVIDS documented MaxxPro driver training at Victory Base Complex as a new engineer company took over work under the 54th Engineer Battalion.

Protected mobility role
The MaxxPro appeared in Iraq as part of the wider U.S. MRAP response to improvised explosive devices and ambush threats. U.S. Army reporting on MRAP ambulances described MRAPs as being used in Iraq and Afghanistan and noted their V-shaped profiles and heavy armor as protection against mines, IEDs, and ambushes.
U.S. Army Operational Test Command later summarized the MRAP mission in Iraq as security for expeditionary units from 2008 onward, increasing survivability and mobility for forces operating in hazardous fire areas and combat zones. The same Army article listed MaxxPro Dash, MaxxPro recovery vehicle, and MaxxPro long-wheelbase ambulance variants in the MRAP test context, while the Iraq-specific MaxxPro sources show the family was sustained and trained in theater.
