The battalion was reactivated March 1, 1941, at Guantanamo Bay, Cuba, as the 2nd Battalion, 1st Marines and was assigned to the 1st Marine Division of the Fleet Marine Force. The force was active for only a brief period of time, during which it was deployed to Marine Corps Recruit Depot Parris Island, South Carolina. The unit was again deactivated on June 14, 1941.
Shortly after the United States entered into World War II, the unit was reactivated February 11, 1942, at New River, North Carolina. It was again assigned to the 1st Marine Division, which deployed in July 1942 to Wellington, New Zealand. The battalion participated in numerous campaigns in the Pacific Theater of WWII, and was a part of the American advance into Japanese territory in the Pacific. The first of these was the Guadalcanal Campaign, during which the battalion defended Henderson Field, an airfield on Guadalcanal, and withstood Japanese bombings of the strategic location. They later participated in Operation Cartwheel, specifically the Battle of Cape Gloucester, during which they withstood several Japanese Banzai charges. Later, during the Battle of Peleliu, the unit suffered heavy casualties during their defense of the Umurbrogal Pocket. In their last engagement in the Pacific, the unit participated in the decisive Battle of Okinawa, taking part in the capture of Shuri during poor weather conditions.
At the close of World War II, in September 1945, the unit was redeployed to Tiensin, China, where they were a part of the occupation of northern China until October 1947, when the unit was deactivated.
2nd Battalion was reactivated August 4, 1950, at Camp Lejeune, North Carolina, and again assigned to the 1st Marine Division, Fleet Marine Force. It was almost immediately deployed to Kobe, Japan in preparation for its participation in the Korean War from September 1950 – July 1953, during which it fought at Inchon-Seoul, Chosin Reservoir, the East Central Front, and the Western Front. After the war, the unit aided in the defense of the Korean Demilitarized Zone.
On September 20, 1950. The 2nd Battalion, 1st Marines set up a L-shaped ambush near Yongdungpo. A North Korean column of hundreds of NKPA troops and five T-34 tanks headed blindly into the ambush set by the Marines. Short-range fire from Marine 3.5-inch bazookas knocked out the first two enemy tanks; a storm of direct and indirect fire cut down the supporting infantry, killing 300 North Korean men. The surviving North Koreans withdrew to their prepared defenses within Yongdungpo.[1]
After the war, in April 1955, the unit was relocated to Camp Pendleton, California, where it participated in the transplacement system between the 1st and 3rd Marine Divisions.
As part of the 15th Marine Expeditionary Unit, the battalion deployed to Kuwait in February 2003, and participated in the invasion of Iraq in March 2003. The battalion deployed in March 2004, to Fallujah, Iraq and took part in Operation Vigilant Resolve. They returned to Iraq in 2005 with the 13th Marine Expeditionary Unit and engaged in combat operations during Operation Steel Curtain in Husaybah, Karabilah, and New Ubaydi, and Operation Iron Hammer in Hit. The battalion deployed to Okinawa to serve as the Ground Combat Unit for the 31st Marine Expeditionary Unit from January 1, 2007, until January 1, 2008. The battalion deployed to Iraq in January 2009 and returned in August of the same year.
The battalion deployed to Afghanistan in October 2010 through May 15, 2011, in support of Operation Enduring Freedom. They operated in the Garmsir District, Helmand Province.

The battalion lost nine Marines and one Navy Corpsman on August 26, 2021, in a deadly suicide bomber attack during the withdrawal from Kabul's Hamid Karzai International Airport.

The attack in total took the lives of 13 American Servicemen and women.[11]
