In January 1944, the battalion deployed to the Pacific, where it participated in several major campaigns, including Kwajalein, Saipan, Tinian, and Iwo Jima. Following the conclusion of hostilities, the unit returned to Camp Pendleton in October 1945 and was deactivated on 20 November 1945.
The battalion was reactivated on 1 February 1967 at Tacoma, Washington, as part of the 4th Marine Division, Fleet Marine Force, U.S. Marine Corps Reserve. In July 1976, it relocated to San Diego, California, and was reassigned to the 4th Force Service Support Group, which was later redesignated as the 4th Marine Logistics Group.
During Operations Desert Shield and Desert Storm from August 1990 to June 1991, 4th Medical Battalion provided critical medical and combat service support to Marine forces in Southwest Asia.
In March 2003, 4th Medical Battalion deployed as a full unit in support of Operation Iraqi Freedom. Upon arrival in Kuwait, it delivered essential medical and logistical support to combat operations across the theater and continued to play an active role throughout the campaign in Iraq.
In 2006, reservists from the San Diego–based Headquarters and Service Detachment were mobilized for combat operations in Al Anbar Province, Iraq, serving alongside 1st Battalion, 24th Marines, Weapons Company, in the city of Fallujah. The following year, in September 2007, additional reservists from the battalion deployed in support of Operation Iraqi Freedom as part of Combat Logistics Battalion 4, Combat Logistics Battalion 8, and Surgical Company Bravo. These elements provided medical support at Camp Fallujah and Camp Taqaddum (Al Taqqadum). The returning members completed their deployment in late March 2008, while follow-on rotations continued to sustain operations at Camp Taqaddum and Korean Village.
From 2008 to 2009, additional elements of the battalion participated in ongoing operations in Iraq. By May 2010, numerous reservists from Headquarters and Service Company had volunteered for deployment to Afghanistan, serving with Provisional Military Police Company and Personal Security Detachment elements in support of Operation Enduring Freedom.
From 2009 to 2012, battalion elements continued to provide medical support to coalition operations in Afghanistan, further demonstrating the unit’s versatility and commitment to global readiness.
Today, 4th Medical Battalion remains an integral component of the Marine Corps Reserve, sustaining a legacy of medical excellence and operational readiness in support of both domestic missions and overseas contingencies.
