The 25th Marines is one of three infantry regiments in the Fourth Marine Division, Fleet Marine Force, United States Marine Corps. From its headquarters at Fort Devens, in Massachusetts, the regiment commands fifteen training centers in nine states throughout the Northeast. These units consist of approximately 3,500 reserve and active duty Marines.
The 25th Regiment of Marines has a proud history. It was activated 1 May 1943, at Camp Lejeune, North Carolina and was initially manned by Marines from throughout the Northeast. The Regiment was subsequently assigned to the 4th Marine Division for service in World War II. Initially located at Camp Pendleton, California, the Regiment was ordered to the Pacific in January of 1944 and participated in the Kwajalein, Saipan, Tinian, and Iwo Jima Campaigns. the Regiment won two Presidential Unit Citations for its participation in these battles. The 25th Marines returned to Camp Pendleton at the end of the war and on 10 November 1945, its job finished, the Regiment was deactivated.
On July 1962, 16 ½ years after its colors had been folded following its service in World War II, the 4th Marine Division was reactivated as a Reserve Division. This reactivation included all three Battalions of the 25th Marines. Since then, the reactivated units have served proudly. They inherited an unfaltering tradition from their World War II predecessors, and from throughout the Northeastern United States, they are continuing the tradition. Reserve Marines of the Regiment have served alongside their regular counterparts in training exercises throughout the world.
In February 1991 the entire Regiment was fully activated for DESERT SHIELD AND DESERT STORM. Although, only 1st Battalion deployed into southwest Asia and participated in the 1st Marine Division's initial breach of Iraqi defenses, the Regimental Headquarters, 2nd and 3rd Battalions mobilized in support of other operational requirements.
In January 2002 the Regimental Headquarters Company and 2nd Battalion, 25th Marines deployed to Camp Lejeune, North Carolina in support of Operations Enduring Freedom and Noble Eagle. After supporting numerous operations in support of the War on Terrorism, Headquarters Company and 2nd Battalion, 25th Marines were deactivated in January 2003.
