When can a citizen be required to take part in the U.S. military service?

A citizen can be required to take part in U.S. military service if drafted. This means that in times of national emergency or war, the government has the authority to compel citizens to serve in the military if they meet certain eligibility criteria.

The draft, officially known as selective service, allows the government to maintain an adequate number of military personnel without relying solely on voluntary enlistment. It is important to note that this requirement is established by law and is part of the responsibilities that citizens have towards their country during critical times.

Volunteering for military service occurs when an individual chooses to enlist, which is distinct from being drafted. Additionally, the obligation to serve is not limited solely to wartime; it can occur in peacetime if the draft is in effect. Retirement age does not impose any military obligations, as citizens are not required to serve once they reach that age.
