There have been women in the United States Army since the Revolutionary War, and women continue to serve in it today. As of 2020, there were 74,592 total women on active duty in the US Army, with 16,987 serving as officers and 57,605 enlisted. While the Army has the highest number of total active duty members, the ratio of women-men is lower than the US Air Force and the US Navy, with women making up 15.5% of total active duty Army in 2020.

History Note that some minor wars women served in have been omitted from this history.

Pre-World War I A few women fought in the Army in the American Revolutionary War while disguised as men. Deborah Sampson fought until her sex was discovered and she was discharged, and Sally St. Clair died in the war. Anna Maria Lane joined her husband in the Army; her pension notes that she was given $100 a year for life in recognition of the fact that she, "in the Revolutionary War, performed extraordinary military services at the Battle of Germantown, in the garb, and with the courage of a soldier."

The number of women soldiers in the American Civil War is estimated at between 400 and 750, although an accurate count is impossible because the women again had to disguise themselves as men.

Dr. Mary Edwards Walker became the first female surgeon in the US Army when she was appointed as Assistant Surgeon of the 52nd Ohio Infantry serving in the Battles of First Bull Run, Fredericksburg, Chattanooga, and Chickamauga. Walker was also the first and to this day the only woman to ever receive the Medal of Honor.

The United States established the Army Nurse Corps as a permanent part of the Army in 1901; the Corps was all-female until 1955.

World War I Approximately 21,000 women served in the Army Nurse Corps during World War I. In 1917 World War I Army nurses Clara Ayres and Helen Wood became the first female members of the U.S. military killed in the line of duty. They were killed on May 20, 1917, while with Base Hospital #12 aboard en route to France. The ship's crew fired the deck guns during a practice drill, and one of the guns exploded, spewing shell fragments across the deck and killing Nurses Ayres and Wood.

Hello Girls was the colloquial name for American female switchboard operators in World War I, formally known as the Signal Corps Female Telephone Operators Unit; during World War I, these switchboard operators were sworn into the U.S. Army Signal Corps. However, not until 1978 did Congress approve veteran status/honorable discharges for the remaining Hello Girls. The Hello Girls were created in 1917 due to a call by General John J. Pershing to improve the worsening state of communications on the Western front. Applicants had to be bilingual in English and French to ensure that orders would be heard by anyone. Over 7,000 women applied, but only 450 women were accepted. Many of these women were former switchboard operators or employees at telecommunications companies.

World War II and after until the Korean War

The Army established the Women's Army Auxiliary Corps in 1942, which was changed to the Women's Army Corps in 1943. Over 150,000 women served as WACs during World War II.

The Angels of Bataan (also known as the "Angels of Bataan and Corregidor" and "The Battling Belles of Bataan"According to research by Dr. Elizabeth Norman, the nurses first referred to themselves as the "Battling Belles of Bataan" in 1942; the phrase "Angels of Bataan" appeared later, in 1945. E. Norman, We Band of Angels, pg. 53, pg 296 note 8.) were the members of the Army Nurse Corps (and the Navy Nurse Corps) who were stationed in the Philippines at the outset of the Pacific War (a theatre of World War II) and served during World War II's Battle of the Philippines (1941–42). When Bataan and Corregidor fell to the Japanese in 1942, they, 66 army nurses (and 11 Navy nurses and 1 nurse-anesthetist) were captured and imprisoned in and around Manila.E. Norman, We Band of Angels, Appx. II; E. Monahan and R. Neidel-Greenlee, All This Hell, pg 193-195 (Appx. G). They continued to serve as a nursing unit throughout their status as prisoners of war.E. Monahan and R. Neidel-Greenlee, And If I Perish: Frontline U.S. Army Nurses in World War II, pg. 19 (First Anchor Books Ed, November 2004)(); E. Monahan and R. Neidel-Greenlee, All This Hell, pg 103. They were freed in February 1945.

In January 1943, Captain Frances Keegan Marquis became the first to command a women's expeditionary force, the 149th WAAC Post Headquarters Company. Serving in General Eisenhower's North African headquarters in Algiers, this group of about 200 women performed secretarial, driving, postal, and other non-combat duties.

In May 1943, Dr. Margaret Craighill became the first female doctor to become a commissioned officer in the Army Medical Corps; she was assigned as the Women’s Consultant to the Surgeon General of United States Army commanding the Women’s Health and Welfare Unit and liaison duty with the WAC. During her military service, she was responsible for inspection of the field conditions for all women in the United States Army. This included providing medical care after enlistment, and recommending hygiene courses and other preventative measures, as well as establishing the standards for screening applicants into the WACs and for WAC medical care. She also met with a board of army doctors to create set standards of acceptability, and these were shortly published. Craighill was also responsible for advising the assignment of women medical officers. She recommended that women be assigned positions that were based on their professional qualifications rather than on their gender.

The United States Army Surgeon General's office issued a circular in 1941 that for the first time classified "homosexual proclivities" as disqualifying inductees from military service; the WAC adopted a similar policy in 1944.Allan Bérubé (1990). Coming Out Under Fire: The History of Gay Men and Women in World War Two. New York, The Penguin Group. , page 32 The WAC instituted strict screening policies for candidates, based on physical appearance and gender and femininity conformity, in order to exclude lesbians from service. WAC policies also condoned heterosexual relationships with servicemen in order to discourage homosexual conduct.

Slightly after the war, in 1947, Florence Blanchfield became the first woman to receive a military commission in the regular army.

In 1948, the Women's Armed Services Integration Act gave women permanent status in the Regular and Reserve forces of the Army.

Korean War and after until the Vietnam War Army women who had joined the Reserves following World War II were involuntarily recalled to active duty during the Korean War. Although no Women's Army Corps unit was sent to Korea, approximately a dozen WACs, including one officer, served in Seoul and Pusan in secretarial, translator, and administrative positions in 1952 and 1953. As well, many WACs served in support positions in Japan and other overseas locations. Over 500 Army nurses served in the combat zone and many more were assigned to large hospitals in Japan. One Army nurse died in a plane crash on her way to Korea on July 27, 1950, shortly after hostilities began.

Vietnam War In 1967, during the Vietnam War, Public Law 90-130 was signed into law; it removed legal ceilings on women's promotions that had kept them out of the general and flag ranks, and dropped the two percent ceiling on officer and enlisted strengths for women in the armed forces. Women's Army Corps soldiers served in the Vietnam War; at their peak in 1970, WAC presence in Vietnam consisted of some 20 officers and 130 enlisted women.

During the war, Anna Mae Hays, Chief of the Army Nurse Corps, became the first U.S. female brigadier general on June 11, 1970. Minutes later, Elizabeth Hoisington, Director of the Women's Army Corps, became the second. An Army nurse (1st LT Sharon Ann Lane) was the only US military woman to die from enemy fire in Vietnam. Two other Army nurses were awarded the Soldier's Medal for heroism in Vietnam; one was African-American 1LT Diane Lindsay, who was the first black woman to receive the award.

Women in the Army from 1972 to 2025

Frontiero v. Richardson, , was a landmark Supreme Court caseTechnically, the case was decided under the Fifth Amendment's Due Process Clause, not under the Equal Protection Clause of the Fourteenth Amendment, since the latter applies not to the federal government but to the states. However, because Bolling v. Sharpe, through the doctrine of reverse incorporation, made the standards of the Equal Protection Clause applicable to the federal government, it was for practical purposes an addition not to due process, but rather to equal protection jurisprudence. which decided that benefits given by the military to the family of service members cannot be given out differently because of sex.

West Point admitted its first 119 female cadets in 1976, after Congress authorized the admission of women to the federal service academies in 1975.
