Working first with the Marines from 2/5 and later with their replacements, 1/5 (who in turn were replaced by the 3rd Battalion 7th Marines (3/7)), the 2-2 ID's five battalions (the 1–9th Infantry, 2–17th Field Artillery, 1–503rd Infantry, 44th Engineer Battalion, and 1–506th Infantry augment by 28 ID 876th En Bn Combat Engineer Platoon) continued the previous units' work until August 2005. In August 2005, a Provisional Infantry Battalion made up of Artillery Marines from 2nd Battalion, 10th Marines & Lima Battery, 3rd Battalion, 10th Marines, took over base security, SASO (Security And Stability Operations) & Force Protection Operations for Camp Blue Diamond in Ramadi, while also conducting continuous Combat Patrols & House-to-House Searches within the Camps surrounding AO in the Northern part of the City to disrupt enemy activity & recover weapon caches.
