Shortly before the outbreak of World War II, the battalion was reactivated deployed to the Pacific theater in June 1942. While there, the unit participated in the bloody "island hopping" campaign, fighting at Guadalcanal, Tarawa, Saipan, Tinian, and Okinawa. After the war, 1/2 spent a brief period on occupation duty in Japan, including Nagasaki, before returning to Camp Lejeune where it stood down in November 1947.
Reactivated again in October 1949, the battalion has since regularly deployed to the Caribbean and Mediterranean regions. 1/2 has seen operational service during the Cuban Missile Crisis (1962), Dominican intervention (1965), operations in the Persian Gulf (1988), Eastern Exit (Somalia evacuation, 1991), Desert Shield and Desert Storm (1990–91), Haitian refugee (1992), Somalia (1993), and Cuba (1994), Operation Noble Obelisk-Freetown, Sierra Leone (1997). The unit has also deployed with the Unit Deployment Program and Camp Lejeune-based MEUs.

In December 2001, the Marines of Bravo Company were recalled off of Christmas leave after completing their six month Unit Deployment Program (UDP) to Okinawa. The Marines were sent to Guantanamo Bay Naval Base, Cuba to provide security for the Guantanamo Bay detention camp, including Camp X-Ray.
Operation Iraqi Freedom
The battalion saw combat during Operation Iraqi Freedom as part of Task Force Tarawa in 2003 and with the 24th Marine Expeditionary Unit in 2004, having combat operations in Iskandariyah, Musayyib, Haswa, and Jurf Al Sakhar, located in the Babil province. In the summer of 2006, the battalion completed their third tour in Iraq as part of the 22nd Marine Expeditionary Unit in Hīt located within the Al Anbar province. In March 2007 the battalion on its 4th combat deployment operated in Kahn ar Bagdadi, Ar Rutbah, Albu Hyatt and Anah, located in Al Anbar province. From July 2008 through February 2009 the battalion deployed to Al Habbaniyah in the Al Anbar province. The battalion also spent a portion of its 5th deployment to Iraq in Sinjar, located in the Ninawa province.
Operation Enduring Freedom
The battalion deployed to Afghanistan in support of Operation Enduring Freedom in March 2010. Their area of operations (AO) included Now Zad, Salaam Bazaar, Karimanda, Kunjak, Musa Qal'eh, Allahu Akbar, and the Musa Qal'eh Wadi down to Sangin. The battalion took heavy casualties but was able to push out a large portion of the Taliban in the AO and double the size of the AO that they were responsible for. For their exceptional actions, First Battalion Second Marines, along with several attachments were awarded the Navy and Marine Corps Presidential Unit Citation. 1/2 came home in late September 2010 when they were relieved by 1st Battalion 8th Marines.
1/2 deployed again in support of OEF in May 2014. The Marines and Sailors will continue to patrol the surrounding area of the Bastion-Leatherneck complex to ensure the safety of coalition forces operating on the bases until full security responsibility of the area is transferred to the Afghan National Security Forces by the end of the year.
