The United States Marine Corps Reserve was established when Congress passed the Naval Appropriations Act of Aug. 29, 1916 and is responsible for providing trained units and qualified individuals to be mobilized for active duty in time of war, national emergency or contingency operations. Marine Forces Reserve also provides personnel and operational tempo relief for active component forces in peacetime.

The Marine Reserve team possesses capabilities across the full spectrum of military operations; from humanitarian assistance and disaster relief support to the most potent combat forces in the world.

Marine Forces Reserve, the largest command in the Corps, has four major subordinate commands: the 4th Marine Division, 4th Marine Aircraft Wing, 4th Marine Logistics Group, and Force Headquarters Group.

Serving with great distinction, in every clime and place, Reserve Marines have regularly operated alongside the active component in both World Wars, Korean Conflict, Vietnam War, Persian Gulf War and numerous other conflicts including Operations Enduring Freedom and Iraqi Freedom.

In order to keep its fighting edge, Marine Forces Reserve’s units participate annually in numerous large exercises in places such as Norway, South Korea, the Balkans, Central America, Thailand and Africa.
