The U.S. Marine Corps Reserve was created on August 29, 1916. Also known as Marine Forces Reserve, it is composed of 40,000 reservists drawn from diverse civilian backgrounds.

Its mission is to augment, reinforce and replenish active duty Marine forces during wartime and national emergencies, as well as provide additional personnel relief to Marine Corps operations during peacetime. As one Marine officer best said during World War II, “When fighting side by side, the labels ‘reserve’ and ‘regular’ melt away.”

To celebrate its birthday on August 29, here are 11 facts you’ll want to know about the citizen-warriors of the Marine Corps Reserve:

1. Of the over 589,000 men and women who served in the Marines during World War II, about 70% were reservists.

2. The 4th Marine Division “The Fighting Fourth” (today, the 4th Division is the reserve division of the Marine Corps; elements of the 4th are stationed throughout the United States) was originally created in 1943 for service during World War II.

Activated on January 13, 1944, it would be the first division to sail from the U.S. directly into combat. The 4th Marine Division spent the next two years in continuous combat in the Pacific Theater, including the battles of Saipan, Tinian and Iwo Jima.

3. The first official “Toys for Tots” campaign was initiated by reservist Maj. William Hendricks in 1948.

It transformed into a nationwide Marine Corps Reserve public affairs project by 1953.

4. In 1918 over 300 women enlisted in the Marine Corps Reserve for service during WWI.

They were nicknamed “Marinettes.” After the war, the women who remained in the inactive reserves received pay of $1.00 per month and medals for victory in WWI and good conduct.

5. During Desert Shield/Desert Storm, the 4th Marine Division was the largest military reserve component activated for duty during the conflict.

From 1990-1991, 63% of the Marine Corps Reserves activated in support of the operation.
