How many men did the US draft in World War 2?

Women work in the professional environment today because so many men were drafted for WWII. There were no men left to run the factories, and women had to do the job. I can only guess to the hundreds of thousands that were drafted... Over 1,000,000 allied forces were involved in D-Day. If my grandma had to pay for sugar with Uncle Sam food stamps, you can bet your keister men were drafted. Hitler was going to conquer the world.
