1- WW2 allowed conscientious objectors which meant not all the men had to fight. They needed more soldiers so women were allowed to join the military. During WW1 the women left behind did the jobs traditionally made for men, which proved that they had the ability to do jobs men did, so they were allowed to fight in WW2.
3- Women in the military showed that women were capable of 'men's jobs', so their traditional gender roles were not upheld so strictly after WW2. It showed that they too were capable of all the things men were, meaning they were treated with more respect.
