The United States Marine Corps Reserve (USMCR) is a reserve component of the United States Marine Corps, consisting of both former active-duty Marines and civilians who have completed Marine Corps boot camp and officer candidate school. The USMCR is a vital part of the Marine Corps’ overall force structure, providing a pool of trained personnel who can be mobilized to support active-duty operations in times of war, national emergency, or other contingencies.
History of the U.S. Marine Corps Reserve

The USMCR has a rich and storied history, dating back to 1916, when the Marine Corps first established a reserve component. Over the years, the USMCR has played a significant role in supporting active-duty operations, from World War I to the present day. During World War II, the USMCR mobilized over 100,000 reservists to support the war effort, and in the Korean War, USMCR units were among the first to be deployed to the theater. In more recent conflicts, such as the Gulf War and the wars in Iraq and Afghanistan, the USMCR has continued to provide critical support to active-duty operations.
Structure and Organization
The USMCR is organized into several major components, including the Selected Marine Corps Reserve (SMCR), the Individual Ready Reserve (IRR), and theInactive Reserve. The SMCR is the largest component, consisting of units and personnel who drill regularly and are available for mobilization. The IRR, on the other hand, consists of Marines who have completed their active-duty service obligation and are no longer drilling regularly, but are still subject to recall to active duty. The Inactive Reserve consists of Marines who have been placed on inactive status due to medical or other reasons.Component | Description |
