The unit fought in the Second Battle of Fallujah as part of Regimental Combat Team 7 to clear the city of insurgents and reclaim the city. In one deployment, BLT 1/3 unfortunately lost more men compared to any Marine Corps Battalion during OIF/OEF. BLT 1/3 has produced one of very few nominations for the Medal of Honor thus far in the Global War on Terror, Sergeant Rafael Peralta.
On January 26, 2005, a CH-53E Super Stallion helicopter crashed in the Al-Anbar province taking with it the lives of 26 Kaneohe Bay Marines, along with one Navy Corpsman and four Marine aircrew from a mainland unit.

The battalion deployed to Karma, Iraq from August 2008 - March 2009. One Marine was killed and five were injured on December 21, 2008.
The battalion again deployed to Afghanistan in November 2009 through June 2010, taking up positions in and around FOB Geronimo, within the district of Nawa-I-Barakzayi, Helmand Province. In February 2010, the battalion participated in Operation Moshtarak, the seizure of the Talibanstronghold of Marjah.[7] The activities of Bravo and Charlie Companies were covered extensively in a series of articles by C. J. Chivers in The New York Times, and in the "At War Blog" posted on The New York Times website. A total of five Marines were KIA, along with one British reporter this deployment.
The battalion deployed once more to Afghanistan in April 2011, taking up positions south of FOB Delhi, in Garmsir District, Helmand Province.
Redesignation and littoral operations
1st Battalion, 3d Marines was redesignated as the 3d Littoral Combat Team on June 23, 2022, at a ceremony on Marine Corps Base Hawaii. This redesignation was driven by the Commandant of the Marine Corps' Force Design 2030 initiative to man, train, and equip forces in the Indo-Pacific capable of supporting sea control and sea denial operations in actively contested maritime spaces.[8]
