Some countries have compulsory military service for all of its citizens.
North America…
While the US hasn’t had a need for peacetime conscription — its war planning has assumed that its peacetime military, especially its navy and air force, could hold off an invader for six months, long enough to train up untrained infantry from scratch – that’s not all countries in North America. I’d guess that Cuba likely has it.

Looks like they have two years of mandatory service.
Conscription is inscribed in the 1976 Constitution of the Republic of Cuba in article 65, stating that “Defense of the socialist homeland is the greatest honor and the supreme duty of every Cuban citizen.”
Cuban nationals were required to serve under the Obligatory Military Service (SMO) system. Under this structure, it was compulsory to complete three years in military service, the militias of territorial troops, or the brigades of production and defence.[2] The SMO was reinforced by the first Law of Military service which was established in November 1963.
As of August 1991, the SMO changed to the General Military Service Law and the requirements of active military service were reduced to two years, with enlistment being obligatory between the ages of 16 and 28, however most nationals were not called to service until they were 17.
Military Service in Mexico (Spanish: Servicio Militar Nacional, or SMN) currently involves all males reaching the age of eighteen years. Selection is made by a lottery system using the following color scheme: those who draw a black ball must serve as “availability reservists”, that is, they are not required to perform any activities whatsoever and will receive their discharge card at the end of the year. Those who draw a white ball must serve “framed” which means, they must start service immediately from 8am-1pm for one year in total, until they receive the discharge card.

Mexico apparently also has it, though there it’s only a randomly-selected subset that are required to serve.
