Aileen Cole Stewart, served stateside caring for German prisoners of war (POWs) and African-American soldiers. They were assigned to Camp Grant, IL, and Camp Sherman, OH, and lived in segregated quarters. 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 Army Signal Corps. This corps was formed in 1917 from a call by General John J. Pershing to improve the worsening state of communications on the Western front. Applicants for the Signal Corps Female Telephone Operators Unit 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. Despite the fact that they wore Army Uniforms and were subject to Army Regulations (and Chief Operator Grace Banker received the Distinguished Service Medal), they were not given honorable discharges but were considered "civilians" employed by the military, because Army Regulations specified the male gender. Not until 1978, the 60th anniversary of the end of World War I, did Congress approve veteran status and honorable discharges for the remaining women who had served in the Signal Corps Female Telephone Operators Unit. The first American women enlisted into the regular armed forces were 13,000 women admitted into active duty in the U.S. Navy during the war. They served stateside in jobs and received the same benefits and responsibilities as men, including identical pay (US$28.75 per month), and were treated as veterans after the war. The U.S. Marine Corps enlisted 305 female Marine Reservists (F) to "free men to fight" by filling positions such as clerks and telephone operators on the home front. In 1918 during the war, twin sisters Genevieve and Lucille Baker transferred from the Naval Coastal Defense Reserve and became the first uniformed women to serve in the U.S. Coast Guard. Before the war ended, several more women joined them, all of them serving in the Coast Guard at Coast Guard Headquarters. These women were demobilized when hostilities ceased, and aside from the Nurse Corps the uniformed military became once again exclusively male. In 1942, women were brought into the military again, largely following the British model. Impact of US forces on the war On
