whats the deference between the women role in world war one and two?

Answer 1

Women were homemakers in WWI and in WWII they became factory workers due to the lack of manpower because the men were gone to war.

Answer 2

In WWI, a relatively few women served as ambulance drivers and nurses. The war (for the US) lasted a relatively short time and the home front was not heavily mobilized.
In WWII, a large percentage of the home workforce was women and they did heavy assembly jobs. They also served as pilots for transfering planes and training of pilots and as nurses and drivers in all theaters. Certain female military units were created that had names like WAVES and WAAF, but the women in these units were almost entirely used for support including offices, radar and air control centers, and finanace offices.
