"Men must enlist for conscription in the year they turn 18. If a citizen is exempted, or if he has finished his military service, he is given one of the following documents: Certificado de Alistamento (commonly known as CAM); Certificado de Reservista; Certificado de Isenção; or Certificado de Dispensa de Incorporação. Without these documents, he won't be able to obtain a Brazilian passport, enroll in any educational institution nor be admitted as an employee in any company whose operations depend on the authorization of federal, state or municipal governments"

Feminists always try to dissmiss this as not a big deal, but I honestly wonder how they would react if there were a requirement to get a job or passport that only women had to comply.
