In the aftermath of the offensive, relative calm was restored to Fallujah although almost-daily attacks against coalition forces resumed in 2005 as the population slowly trickled back into the city. From 2005–06, elements of the New Iraqi Army's 2nd and 4th brigades, 1st Division, occupied the city while the Marines maintained a small complex consisting of a security element from RCT8 and a CMOC at the city hall. The Iraqi units were aided by Military Transition Teams. Most Marine elements stayed outside of the city limits.
