OPERATION IRAQI FREEDOM- I 2002-2003:

In July 2002, the battalion began to prepare by conducting mechanized operations as part of a likely invasion of Iraq. During this pre-OIF period the battalion conducted the 1st Tactical Small Unit Leaders Course (TSULC), participated in a Battalion Mechanized/Fire Support Field Exercise, and supported a STEEL KNIGHT Exercise. In January 2003, the battalion deployed to Kuwait and rehearsed mechanized operations as Task Force 3/4. On 21 March, the battalion invaded Iraq as one of the Battalion Task Forces that made up Regimental Combat Team - 7 (RCT-7). During the invasion, the battalion fought and captured key objectives to include the Basrah International Airport and the Basrah Oil Refinery. Throughout the next several weeks the Battalion Mechanized Task Force fought its way north and conducted battles along Route 1, Ad Diwaniyah, Afak, Al Budyhar, and Al Kut. Eventually the Battalion fought its way through a military complex on the east side of the Nahr Diayla Canal. It was here that the battalion executed its famous infantry assault crossing a blown up bridge at Azza Fayraniah and became officially the first Marine Corps elements to cross into the city of Baghdad. Soon after crossing into Baghdad, the Battalion fought its way through light resistance to the area near the Palestine Hotel and pulled down the Saddam Hussein Statue.

During this period, the famous call sign "Darkside" was born.

OPERATION IRAQI FREEDOM-II 2004:

While in Okinawa on UDP, the Battalion received the deployment order for OIF II. During the period from December 2003 - January 2004 the battalion maximized its time by preparing plans and conducting Stability and Support Operations (SASO). Since the Battalion was one of two infantry Battalions in Okinawa deploying to OIF II, they had priority on ranges and were able to use Camp Schwab to execute patrolling, cordon and search, and convoy operations as part of their training. The unit then redeployed to the Al Anbar Province of Iraq in February 2004. During this deployment, the battalion operated in the cities of Haditha, Anah, and Rawah and participated in Operation VIGILANT RESOLVE (Battle of Fallujah I). The battalion returned home to the Twentynine Palms in July 2004.

OPERATION IRAQI FREEDOM-III 2005:

In January 2005, the battalion redeployed to Fallujah, Iraq to conduct security operations in support of the first Iraqi elections in 40 years.

On Father's Day, 19 June, the Marines of Weapons Company foiled a well coordinated enemy combined arms ambush. The Battalion redeployed to Twentynine Palms in July 2005.

OPERATION IRAQI FREEDOM (05-07) 2006-2007:

In September 2006, the battalion redeployed to Iraq operating in the areas of Al Qa’im, Hit, and Anah. This combat deployment was defined by small units operating independently and partnering/embedding with their Iraqi counterparts. During this deployment the battalion conducted the full spectrum of Counter-Insurgency Operations (COIN). The end result was that the Darkside played a big role in what become known as the military "surge" in Iraq. This "surge" help set the conditions for victory in Iraq. After being extended for two extra months, the battalion redeployed back to Twentynine Palms in May 2007.

OPERATION IRAQI FREEDOM (08.1) 2008:

In February 2008, the battalion returned to Iraq inheriting a 2,600 square mile area of operations. The dynamics of this Iraq deployment had dramatically changed from previous deployments. Although Iraq was still a dangerous place, attacks on U.S. forces, especially attacks on Marines in the Al Anbar Province had dramatically decreased. The U.S. military "surge" of 2007 worked. This next phase of counter-insurgency operations was defined by transitioning to Iraqi control. During this combat tour the battalion conducted relief in place with 1/7 in the Hit district and with 3/23 in the Haditha district. The battalion began the deployment spread out in over 28 separate combat outposts and expeditionary patrol bases. Distributed operations was the modus operandi. Over time the battalion transitioned from being embedded and partnered with the Iraqi Security Forces (ISF) to what became known as OPERATIONAL OVERWATCH. By September 2008, the battalion had consolidated down to 4 total outposts and had set the conditions for Iraqi Provincial Elections and independent Iraqi security operations. The battalion returned home to Twentynine Palms in September 2008.
