The battalion once again deployed to Southwest Asia from January 2003 to July 2003 to support the 1st Marine Expeditionary Force (I MEF) in Operation Iraqi Freedom.

Immediately following the fall of Baghdad, the battalion assumed the mission of a Provisional Infantry Battalion and begun assisting in civil/military duties as well as conducting Security and Stability Operation (SASO) patrols in the capital city, securing hospitals and other vital infrastructure.

In November 2003 the battalion again received orders to deploy to Iraq, but this time as a Provisional Military Police Battalion.

In May 2005, the battalion became the first unit in the world to field the new M777 lightweight howitzer. Feedback from the artillerymen of 3/11 led to modifications prior to being issued to other Marine and Army units.
