With international tensions continuing to raise concerns about the possibility of a wider global conflict, some Americans are questioning whether they could be required to join the military if the United States went to war.
Although the US has not used compulsory military conscription since 1973, the government maintains a system designed to identify potential recruits if a future national emergency requires additional military personnel.
However, the rules are more complicated than simply calling up every adult who is physically capable of serving.
Age, medical fitness, family circumstances and certain other factors could all influence whether someone would ultimately be required to serve.
Who would be drafted first if the US went to war?
Under the existing Selective Service framework, men aged 18 to 25 form the main pool of potential military recruits, with those turning 20 during the year of a draft expected to be considered first.
The Selective Service System explains that, if Congress and the president authorised a draft, a national lottery would determine the order in which eligible men were called for evaluation.
The initial selection group would consist of men turning 20 that calendar year.
If more recruits were needed, the process would extend to older groups, followed by younger eligible men.
The planned sequence is:
Being selected in the lottery would not automatically mean being sent into combat. Individuals would still undergo an evaluation to determine their suitability for military service and whether any exemptions or deferments applied.
Which Americans would be least likely to be drafted?
Several groups would be outside the ordinary draft pool or could qualify for exemptions under existing rules.
Women are not currently required to register for Selective Service, while men aged 26 and older are generally outside the standard registration age range.
Men younger than the minimum induction age would also not ordinarily be called under the existing framework.
However, Congress could amend the rules if it authorised a future draft, meaning current exclusions should not be treated as permanent guarantees.
Could medical conditions prevent someone from being drafted?
Medical fitness would play an important role in determining whether a person could serve.
People with certain serious physical or mental health conditions may be found medically unqualified following an assessment.
Depending on severity and individual circumstances, conditions affecting the heart, lungs, mobility or other aspects of health could influence eligibility.
However, having a medical diagnosis does not automatically mean someone is exempt.
The military would assess individuals against the medical standards applicable at the time.
Importantly, men with disabilities may still be required to register for Selective Service even if they believe they would be unable to serve.
Would parents and caregivers be exempt?
Family responsibilities could also affect whether someone was required to serve.
Under previous draft systems, individuals facing certain severe family hardship or dependency circumstances could request deferments.
For example, someone who provides essential support to a dependent family member might have grounds to request special consideration.
However, being a parent or caregiver does not automatically guarantee exemption.
Any claim would need to be assessed under the rules established for a future draft.
Would women be drafted in World War Three?
Under the current Military Selective Service Act, women are not required to register for the draft.
Although women can serve in combat positions within the US military, compulsory registration remains limited to men under existing federal law.
Changing that requirement would require congressional action.
Lawmakers have previously debated expanding registration requirements, but the current framework has not been extended to women.
Could essential workers avoid military service?
Some civilian occupations could potentially receive special consideration during a major national emergency.
Keeping hospitals, energy networks, communications systems and other critical services operating would remain important during wartime.
As a result, policymakers could establish deferments for certain essential roles.
However, there is no universal guarantee that working in healthcare, cybersecurity or another critical industry would automatically prevent someone from being drafted.
Any occupational exemptions would depend on the legislation and regulations governing the draft.
What happens if someone refuses to fight?
People with sincerely held moral, ethical or religious objections to participating in war may be able to apply for conscientious objector status.
Depending on the classification granted, an individual might be assigned noncombatant military duties or alternative civilian service.
However, conscientious objectors are still generally required to register with Selective Service if they otherwise meet the registration requirements.
They cannot obtain advance classification as conscientious objectors while no draft is operating.
Is the US currently drafting civilians?
No. As of October 2026, the United States does not have an active military draft.
The country has relied on an all-volunteer military since 1973.
Selective Service registration is a contingency measure intended to help the government respond if compulsory recruitment is authorised in the future.
Congress and the president would need to authorise a draft before civilians could be called up through that system.
Legislation introducing automatic Selective Service registration is scheduled to take effect in December 2026, but automatic registration does not mean automatic military enlistment.
While international tensions have renewed public interest in conscription rules, there has been no announcement that the United States is reinstating compulsory military service.
For now, the existing framework explains who might be considered if a future draft were authorised, rather than identifying people who are currently being ordered to serve.
