As global tensions rise, many Americans are concerned about a potential military draft. While the United States currently uses an all-volunteer force, the Selective Service System remains the framework for conscription during a national emergency.
All male U.S. citizens and immigrants aged 18 to 25 must register. By late 2026, this enrollment will become automatic. If a draft were called, a lottery would select 20-year-olds first, followed by those aged 21 through 25.
Several groups are currently exempt from service. Women are not required to register or serve under existing laws. Additionally, anyone with a serious medical or mental health condition that makes them “unfit for duty” would be excused after an evaluation.
Conscientious objectors who oppose war on moral or religious grounds may be assigned to non-combat roles. Deferments are also available for ministers, certain elected officials, and primary caregivers who provide essential support for children or elderly dependents.
In a modern conflict, the military values specialized skills. Professionals in healthcare, engineering, and cybersecurity are often redirected into support roles rather than the front lines. Students finishing their degrees may also receive temporary delays. Experts stress that a draft is a last resort, as modern warfare depends more on technology than high troop numbers.
