Marine and Army units in Ramadi rotate on overlapping schedules; thus, just as 1 BCT 1ID arrived well before the 1st Marine Division officially began OIF 2, so the 2nd Brigade,
2nd Infantry Division (2-2 ID) arrived in August 2004, while the 1st Marine Division was still in charge of Anbar. 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, HQ 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. Squads from 2/10 would also rotate on a regular basis to help support Marine Units tasked with defending al Anbar's Provincial Government Center located within the heart of Downtown Ramadi, a high priority target for the enemy. Convoy Security during transportation of currency & VIP'S to & from the site was also provided by 2/10 Marines. 2/10 was relieved in February 2006 & turned over control to the Army's 1st Battalion, 35th Armor (Task force Conqueror). Eventually, the Iraqi Army's 7th Infantry Division would officially take control of Camp Blue Diamond on May 9, 2006. In April 2005, HHC and B Company 983 Engineer BN (Combat Heavy) were removed from FOB Speicher in order to support 2ID in construction operations. Quality of life improvements of both American forces as well as ISF. CoB 983 supported many construction operations in East Ramadi as well as Blue Diamond and Hurricane Point. During this period the brigade and the Marine battalions that worked with it continued to suffer steady casualties. Unlike the mechanized 1BCT 1ID, 2-2 ID was mostly a
light-infantry brigade (1–9 Infantry is a
mechanized infantry battalion), whose only
tanks came from one company (Death Dealer Company) of the
2–72nd Armor. The 2–28th BCT was reinforced further in July, with the
2–69th Armor HHC Co., Able Co. and Delta Co, a combat-experienced
3rd Infantry Division unit, being sent to it from
Baqubah. The 2–69th Armor remained in Ramadi until January. During September 2005, the 2–28th BCT suffered casualties as insurgent groups were pushed downriver by Marine offensives near
Al Qaim and in the area around
Haditha. Marine and 3rd Infantry division units that replaced the 503rd and 1/5 were doing the majority of rigorous counter-insurgency in the City center The 3rd Bn 172nd Cav from the VT National Guard was at FOB Ramadi during the Iraqi Election period however their exact rotation dates and mission is unclear to this poster. Among the Army Combat Support units in Ramadi during this period were 2nd Platoon, 51st Transportation Company (convoy escort M1114 HMMWVs and M1070 PLS systems) from Mannheim Germany, 2nd Platoon, 2nd Military Police Company as well as HHC and B Company, 983rd Engineer Combat Battalion (Heavy), and US Naval Mobile Construction Battalion 5, who greatly improved quality of life and force protection at American and Iraqi camps, as well as providing security and support for the first democratic elections and the subsequently elected government in Ramadi. The 224th Combat Engineer Battalion (Iowa Army National Guard) served as the Divisional Engineer Battalion, conducting route clearance operations in support of first the 1st Marine Division from January – March 2005, and then to the 2nd Marine Division from March – December 2005, when it was replaced by the 54th Engineer Battalion, a component of the
130th Engineer Brigade,
V Corps based in
Germany. The 54th remained in Ramadi until October 2006 and suffered six fatalities. ==April–May 2006==
