The Selective Training and Service Act of 1940 established America's first peacetime military draft, requiring men aged 21-35 to register for service, eventually mobilizing over 10 million men for World War II.
World War II transformed America's military landscape through one of the most significant mobilizations in U.S. history. The implementation of the military draft, also known as conscription, played a crucial role in building the nation's armed forces to combat the Axis powers.
The Selective Training and Service Act, signed by President Franklin D. Roosevelt on September 16, 1940, marked the first peacetime draft in American history. This historic legislation required all men between 21 and 35 to register for military service, representing a dramatic shift in U.S. military policy as the world descended into war. Within just a few years, the draft would help expand America's military from under 500,000 troops to over 12 million service members.

Military Draft Operations During WW2
#The military draft operations during World War II functioned through a decentralized network of local draft boards implementing standardized selection procedures. These operations established systematic processes for registering managing millions of potential service members.
Local Draft Board System
#The Selective Service System operated through 6,443 local draft boards across the United States during World War II. Each board consisted of 3-5 civilian volunteers appointed by the President who evaluated registrants based on established criteria. The boards maintained detailed records of registered men assigned classifications from 1-A (available for service) to 4-F (unfit for service). Local boards processed an average of 200 registrants per month managing quotas assigned by state draft directors.
| Draft Board Statistics (1940-1945) | Numbers |
