The Women's Army Corps (WAC) was the women's branch of the United States Army. It was created as an auxiliary unit, the Women's Army Auxiliary Corps (WAAC) on 15 May 1942 by Public Law 554, and converted to full status as the WAC on 1 July 1943. Its first director was Oveta Culp Hobby, a prominent society woman in Texas. The WAC was disbanded in 1978, and all units were integrated with male units.
The WAAC's organization was designed by numerous Army bureaus coordinated by Lt. Col. Gilman C. Mudgett, the first WAAC Pre-Planner; however, nearly all of his plans were discarded or greatly modified before going into operation because he expected a corps of only 11,000 women. Without the support of the War Department, Representative Edith Nourse Rogers of Massachusetts introduced a bill on 28 May 1941, providing for a women’s army auxiliary corps. The bill was held up for months by the Bureau of the Budget but was resurrected after the United States entered the war and became law on 15 May 1942. A section authorizing the enlistment of 150,000 volunteers was temporarily limited by executive order to 25,000.
The WAAC was modeled after comparable British units, especially the ATS, which caught the attention of Chief of Staff George C. Marshall. In 1942, the first contingent of 800 members of the Women's Army Auxiliary Corps began basic training at Fort Des Moines Provisional Army Officer Training School, Iowa. The women were fitted for uniforms, interviewed, assigned to companies and barracks and inoculated against disease during the first day.
The WAAC were first trained in three major specialties. The brightest and nimblest were trained as switchboard operators. Next came the mechanics, who had to have a high degree of mechanical aptitude and problem solving ability. WAC armorers maintained and repaired small arms and heavy weapons. The bakers were usually the lowest scoring recruits and were stereotyped as being the least intelligent and able by their fellow WAACs. This was later expanded to dozens of specialties like Postal Clerk, Driver, Stenographer, and Clerk-Typist. The WAC provided enlisted seamstresses to tailor WAC uniforms to their wearer - a service they also provided to male officers.
