For these actions, the battalion was twice awarded the French Croix de Guerre with Palm and once with Gold Star.

The battalion participated in the landing at Inchon, the liberation of Seoul, the Chosin Reservoir Campaign, and the defense of the East Central and Western Fronts. From July 1953 to February 1955, 2nd Battalion, 5th Marines assisted in the defense of the Korean de-militarized zone after which it returned to Camp Pendleton.

In 1959, the battalion deployed to Camp Schwab, Okinawa, and then in 1960, relocated to Camp Pendleton. In April 1966, the battalion deployed to the Republic of Vietnam. During the next five years the battalion participated in combat operations in Hue city, Que Son, Phu Bai, Dong Ha and Phu Loc. The battalion returned to Camp Pendleton in 1971, and in 1975 participated in Operation New Arrival, the relocation of Southeast Asian Refugees.

During the next fifteen years, the battalion deployed regularly as part of the Marine Corps Unit Deployment Program. In December 1990, 2nd Battalion, 5th Marines sailed for the Persian Gulf and participated in Operations Desert Shield and Desert Storm. 2nd Battalion, 5th Marines landed in Saudi Arabia and participated in the liberation of Kuwait.

In March, the Battalion attacked into Iraq, freed the Iraqi people and conducted peacekeeping operations in Muthanna Province until its redeployment in August. The Battalion earned its 14th Presidential Unit Citation for the Operation Iraqi Freedom campaign.

In August of 2004, the Battalion once again deployed to Iraq to participate in Operation Iraqi Freedom II in Ar Ramadi, Iraq.

2nd Battalion, 5th Marines is the most highly decorated battalion in the United States Marine Corps. Its motto comes from its actions at Belleau Wood during WW I. The fleeing French advised the newly arrived Marines to retreat in the face of overwhelming odds. The Battalion’s response: “Retreat, Hell!”
