USMC Reserve

The United States Marine Corps Reserve (USMCR) was established on August 29, 1916, as part of the Naval Appropriations Act, to provide a ready force of trained Marines available for active duty in times of war or national emergency. The USMCR played a significant role in both World Wars, Korea, Vietnam, and the Global War on Terror, augmenting and reinforcing active-duty Marine units. Reservists have participated in every major conflict since World War I, often deploying alongside their active-duty counterparts. Today, the USMC Reserve continues to provide operational flexibility, strategic depth, and community engagement, upholding the Marine Corps’ motto of “Semper Fidelis.”
