Direct proof of use
The BMR-600 Pegaso is directly documented in the 2003 Iraq War through reporting on Spain's Plus Ultra Brigade. Small Arms Review reported that the brigade's main armored support was entrusted to 15 Spanish-designed and Spanish-built BMR and VEC armored vehicles, and placed the Spanish contingent at Base Espana in Diwaniyah and Base Al Andalus in Najaf.
A Spanish Ministry of Defense cavalry memorial provides more specific operational context. In its account of Operation IF in Iraq, it describes Spanish cavalry and supporting units using VEC and BMR vehicles for convoy escort, reconnaissance, patrol, reserve support, and reinforcement during operations around Najaf and Diwaniyah.

Timeline
Small Arms Review dates the first Plus Ultra Brigade elements to 13 July 2003, reports that the brigade was in theater by 13 August, and says it was fully operational by 1 September 2003. The same account states that brigade elements began patrolling Ghammas, Afkar, and Al Budayr after the handover from U.S. Marines to the multinational division.
The later Spanish cavalry account records BMR and VEC activity during the 2004 fighting and withdrawal period. It describes escort, reconnaissance, patrol, reserve, and reinforcement tasks in the Spanish area, including a 26 April 2004 Diwaniyah-area engagement in which VECs and BMRs were used or called forward while Spanish forces responded to Mahdi Army fire.

Operational role
In this conflict, the documented user was Spain's contingent in the Plus Ultra Brigade, part of the United States and coalition side of the 2003 Iraq War. The sourced record supports Spanish BMR use as armored support for stabilization-force movement and protection rather than as Iraqi government, insurgent, or militia equipment.
The BMR's role was protected mobility and force protection for Spanish and coalition activity in south-central Iraq. Small Arms Review identifies the BMR/VEC vehicle group as the brigade's main armored support, while the Spanish cavalry account shows BMRs supporting convoy escorts, reserve movement, and reinforcement alongside VEC reconnaissance vehicles and other Spanish assets.
The available sources do not separate every BMR from every VEC in each incident, so the strongest claim is that BMR-family armored vehicles were fielded by Spanish forces in the Plus Ultra Brigade and used for protected movement and security tasks around Diwaniyah and Najaf.
