I though it was weird that the United States had a requirement for people to physically sign a paper to do it. It looks like only this year they made it automated.
> Beginning on December 18, 2026, the Selective Service System will be required to identify, locate, and register all male (as assigned at birth) U.S. residents 18 to 26 years old on the basis of other existing federal databases. Men will no longer be required to register themselves or be subject to penalties for failing to do so. This was noted to be the most significant change to Selective Service since the self-registration system began in 1980.
To clarify: every young person regardless of gender is legally obliged to go through fitness testing for conscription and if deemed suitable must go through it if selected. I imagine it’s roughly similar in Denmark?
Up until the fall of the USSR ~all men did go through conscription/basic military training. After the fall only the ones that wanted to and were selected did. Now it’s ramping up massively.
