As global tensions rise and the United States takes a more assertive stance internationally, an old question has resurfaced: who would be drafted if a major conflict required reinstating the military draft? Although the U.S. has relied on an all-volunteer force for decades, the Selective Service System (SSS) remains fully operational, ready to be activated by Congress and the president.
Historically, the draft has had a profound impact. During the Vietnam War, 1.8 million men were conscripted, with 17,671 losing their lives in combat. While the last inductions occurred in 1973, registration requirements have persisted: nearly all U.S. male citizens and male immigrants must register within 30 days of turning 18, with late registration allowed until age 26. Failure to comply carries severe consequences, including fines, imprisonment, loss of federal aid or job opportunities, and delays in immigration processes. This registry serves as the pool from which a future draft would be drawn.
If a global crisis escalated to World War III, the draft process would begin in Congress, which would need to amend the Military Selective Service Act to authorize conscription. Once activated, the SSS would conduct a national lottery to determine induction order. Priority would go to those turning 20 in the year of the lottery, followed by those aged 21 to 26. Men aged 18 and 19 would not be called until older cohorts were exhausted.
Once selected, individuals would report to a Military Entrance Processing Station (MEPS) for physical, mental, and moral evaluations. While standards for health, education, and criminal history exist during peacetime, experts note these can be relaxed in large-scale emergencies. Those who are overweight, lack high school diplomas, or have certain criminal records might still be inducted under “moral waivers” if the military needs personnel urgently. Selected individuals could be required to report to the Department of Defense within just 193 days of authorization.
Currently, only men are required to register for the draft, though discussions have occurred about including women, reflecting their expanded role in combat. No such change has been enacted, meaning young men would form the first wave of a conscripted force.
While the draft remains a contingency plan, it is not purely theoretical. Rising geopolitical tensions around the world have revived conversations about national service. The Selective Service System exists as a ready framework to scale the U.S. military from hundreds of thousands to millions in a matter of months. For Americans aged 18 to 25, the lottery of birth dates could determine their fate in a major global conflict, transforming a generation into the nation’s next line of defense.
