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. 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. WAC armorers maintained and repaired small arms and heavy weapons that they were not allowed to use.
