Were women allowed in the military during WWII?

In some places, women were allowed to serve in combat roles in the military during World War II.  One example of this are the women who served in the Russian Red Army.  In most countries, however, women did not serve in combat roles.  They did serve in the military in non-combat roles. 

In the United States, the WASPs were the Women's Airforce Service Pilots.  They were trained to fly military aircraft, though their missions did not involve combat.  They flew planes in the United States when there were not enough men available to do so.  The WAACs were the Women's Army Auxiliary Corps.  The WAAC later became the WAC, Women's Army Corps.  Under these two titles, women served in uniform overseas.  Primarily, these women did clerical work or mechanical jobs.  They did not see combat, but they were prepared to do their part in whatever ways were necessary.  Other countries, such as Britain, had similar organizations for women.
