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.

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.
