Final answer:
During WW2, the volunteer army had successes, especially the women who joined the industrial workforce as part of the war effort and African Americans who advanced civil rights initiatives through the Double V campaign. Both groups significantly contributed to the success of the war effort and societal change.
Step-by-step explanation:
The volunteer army during World War II had notable successes, both on the home front and in the broader context of societal change. Two significant successes include the contribution to the industrial workforce, particularly by women and African Americans, and the advancement of civil rights through the Double V campaign.
Women, symbolized by the iconic Rosie the Riveter, took on roles traditionally held by men, boosting war production through work in munitions factories and other industrial jobs. This was essential to maintaining the war effort while men served overseas. The American Red Cross also saw millions of women volunteer, taking on roles such as community organizers and packers of medical supplies and care packages for prisoners of war.
African Americans, through the Double V campaign, not only fought fascism abroad but also combated racial discrimination at home. They volunteered in various capacities, from civil defense workers to industrial laborers, like those completing the pilot's compartments of aircraft. Their service and activism during the war led to a tenfold increase in NAACP membership and set the stage for future civil rights advancements. Additionally, their role in shifting public perception and advocating for equal rights was an intangible yet crucial success of their wartime contributions.
