#The Selective Service System required all men between 21-45 to register for military service. The age range expanded in 1942 to include men 18-37 for combat duty while those 38-45 received assignments to non-combat positions. Specific exemptions applied to:
- Married men with dependents
- Essential industrial workers
- Agricultural workers
- College students completing degree programs
- Religious ministers ordained clergy
Classification System
#The draft boards assigned registrants into four primary categories based on their eligibility for service:
- Class I-A: Available for military service
- Class I-B: Available for limited military service
- Class II: Occupational deferment for essential civilian work
- Class III: Deferred due to dependents
- Class IV: Unfit for military service
- Physical examination by military doctors
- Mental aptitude testing
- Personal interview with draft board officials
- Review of occupation essential civilian status
- Verification of dependent claims documentation
| Classification Statistics (1940-1941) | Number of Registrants |
|---|---|
| Total Registered | 16,000,000 |
| Class I-A | 2,000,000 |
| Occupational Deferments | 1,500,000 |
| Physical/Mental Disqualifications | 3,500,000 |
Evolution of Draft Requirements During WW2
#The attack on Pearl Harbor triggered significant changes in U.S. military draft requirements as the nation mobilized for total war. Draft policies underwent rapid modifications to meet increasing personnel demands across all military branches.
Changes After Pearl Harbor
#The Selective Service System implemented immediate changes following the December 7, 1941 attack. Local draft boards accelerated processing times from 90 days to 10 days between classification and induction. The quota system shifted from monthly to weekly assignments to meet urgent deployment needs. Physical examination standards relaxed, allowing recruitment of men with minor medical conditions previously deemed unfit for service. By January 1942, draft boards increased their monthly induction rates from 50,000 to 200,000 men.
Expanded Age Ranges
#Congress amended the Selective Training and Service Act in 1942 to broaden the registration requirements:
- Age range expanded to 18-45 for military service
- Combat duty restricted to men aged 18-37
- Non-combat roles assigned to men aged 38-45
- Registration mandated within 5 days of 18th birthday
- College deferments limited to specific technical programs
| Year | Age Range | Monthly Draft Quota | Total Registrants |
|---|---|---|---|
| 1940 | 21-35 | 50,000 | 16 million |
| 1942 | 18-45 | 200,000 | 31 million |
| 1943 | 18-45 | 300,000 | 36 million |
These modifications enabled the armed forces to maintain adequate personnel levels throughout the war while ensuring critical civilian industries retained essential workers.
Impact on American Society
