How did women participate as workers during war with the US?

Women were represented not only as warriors but also as workers; they were shown with a rifle in one hand and a hammer in the other. Whether young or old, women began to be depicted as selflessly working and fighting to save the country. As casualties in the war increased in the 1960s, women were urged to join the struggle in large numbers. They helped in nursing the wounded constructing unground rooms and tunnels.
