United States Marine Corps Women's Reserve

The United States Marine Corps Women's Reserve served in two World Wars before becoming a part of the regular United States Marine Corps.

World War I service
Faced with manpower shortages in 1918, Major General Commandant George Barnett asked the Secretary of the Navy's permission to enlist women for clerical duties. On 13 August 1918, Opha Mae Johnson became the first woman to enlist in the Marines. Some 300 women entered the Marine Corps in 1918, taking over stateside clerical duties from battle-ready Marines needed overseas. The women were nicknamed Marinettes

World War II service
The Marine Corps Women's Reserve was officially established on 13 February 1943. The first director of the Marine Corps Women's Reserve was Major Ruth Cheney Streeter from Morristown, New Jersey. By the end of World War II, 85% of all enlisted U.S. Marine Corps personnel assigned to Headquarters were women. The MCWR was often referred to as the "Lady Marines," but with other women's organizations in the U. S. Military being given catchy names such as WACs, WAVES, and WASPs, one female reporter thought of the name "BAM"s for "Beautiful American Marines"; however many regular Marines called them "Broad Ass Marines"

Training
Initially, the Marine Corps relied upon the Navy's training facilities for both its officers and its enlisted women. Classes began in March 1943 for both officer candidates and recruits. The first group of women officers received direct commissions, based on their ability, education, and civilian expertise. On 13 March 1943, just one month after the Marine Corps began accepting women, the first class of officer candidates began training at Mount Holyoke College in South Hadley, Massachusetts. The first class of recruits (722) completed their recruit training at Hunter College in The Bronx, New York. In July 1943, the Marine Corps transferred the officer and recruit training to more permanent facilities in New River, North Carolina. Nearly 19,000 women would complete their training at New River during the course of the war.

Assignments
The women were assigned to over 200 different jobs, among them: radio operator, photographer, parachute rigger, driver, aerial gunnery instructor, cook, baker, quartermaster, control tower operator, motion picture operator, auto mechanic, telegraph operator, cryptographer, laundry operator, post exchange manager, stenographer, and agriculturist. They would serve as the trained nucleus for possible mobilization emergencies. The demobilization of the Marine Corps Women's Reserve of 820 officers and 17,640 enlisted was to be completed by 1 September 1946. Of the 20,000 women who had joined the Marine Corps during World War II, only 1,000 remained in the Marine Corps Women's Reserve on 1 July 1946.

On 12 June 1948, the United States Congress passed the Women's Armed Services Integration Act, and made women a permanent part of the regular Marine Corps.

In 1950, the Women Marine Corps Reserves mobilized for the Korean War and 2,787 women were called to active duty. By the height of the Vietnam War, about 2,700 women had served both stateside and overseas. By 1975, the Marine Corps had approved the assignment of women to all occupational fields, except the infantry, artillery, armor, and pilot-air crew. Over 1,000 women were deployed in Operations Desert Shield and Desert Storm in 1990–1991.
